Guide to the NEBOSH International Diploma in Occupational Health and Safety Foreword The NEBOSH National Diploma in Occupational Health and Safety has for many years been the flagship NEBOSH qualification and was the first UK vocational qualification to be developed specifically for health and safety practitioners. Since its introduction in 1988, the National Diploma has become established as the most popular professional qualification for health and safety practitioners in the UK, with over 10,000 candidates having achieved the qualification. As globalisation gathers pace and begins to set the tone for all sorts of human activity and interaction, so NEBOSH has seen the need for a common and consistent standard for achieving and maintaining the health and safety of workers in all parts of the world. In recognition of these changing circumstances in an increasingly interdependent world, we have developed this new international qualification to provide the specialist knowledge and understanding combined with the application of the expertise that underpins competent performance as a health and safety practitioner. It also delivers a mainstream route to a qualification for an aspiring practitioner, while allowing those with a basic health and safety qualification (such as the NEBOSH International General Certificate) to develop a professional career path. It also provides a sound basis for progression to an MSc or more specialist study (such as the NEBOSH National Diploma in Environmental Management). The NEBOSH International Diploma is modelled on the NEBOSH National Diploma. The key difference between the two qualifications is in the applicability of legal requirements. Rather than be guided by a specifically UK framework, the International Diploma takes a risk management approach based on best practice and international standards, such as the International Labour Organisation (ILO) codes of practice, with special reference to models such as the ILO's "Guidelines on Occupational Safety and Health Management Systems" (ILO-OSH 2001). Underpinning knowledge of legal frameworks is included and local laws and ultural factors should form part of the study programme where relevant and appropriate. On successful completion of the qualification, the Diploma holder may apply for Graduate membership (Grad IOSH) of the Institution of Occupational Safety and Health (IOSH), the major UK professional body in the field (www.iosh.co.uk). This is the first step to becoming a Chartered Safety and Health Practitioner as a Chartered Member of IOSH (CMIOSH). This qualification is also accepted by the International Institute of Risk and Safety Management (www.iirsm.org) as meeting the academic requirements for full membership (MIIRSM). United Kingdom professional health and safety bodies have a growing international reputation with a number of international branches being formed. In addition, diplomates will have the opportunity to attend the annual NEBOSH Diploma Graduation ceremony.

The syllabus is divided into four units, each of which is assessed separately; three by written examination (Units IA, IB, IC) with a separate written assignment (Unit ID) designed to test knowledge across the syllabus. This unitised structure is intended to provide opportunities for additional and more flexible course formats. On passing each individual unit, candidates will receive a unit certificate from NEBOSH denoting their achievement. On successful completion of all four units, the NEBOSH International Diploma in Occupational Health and Safety will be awarded. The International Diploma syllabus has been revised and updated following the initial pilot stage and stakeholder consultation for launch as a ‘full’ NEBOSH qualification. This Guide supports the syllabus for the International Diploma by giving additional guidance and background material for both tutors and candidates. Further information about NEBOSH qualifications can be found at: www.nebosh.org.uk. NEBOSH welcomes comments on this Guide, and on any other aspect of the International Diploma qualification.

Guide to the NEBOSH International Diploma in Occupational Health and Safety
1. Introduction 1.1 The NEBOSH National Diploma in Occupational Health and Safety has been
recognised for many years as a leading qualification in the field of health and safety, providing the specialist knowledge and understanding combined with the application of the expertise required to undertake a career as a health and safety practitioner. As the name suggests, the International Diploma in Occupational Health and Safety is an international version of the qualification that is intended to fulfil the same objectives for those practitioners operating outside the UK.
1.2 The International Labour Organisation (ILO) estimates that approximately 2 million
workers per year are killed by occupational injuries and illnesses, equivalent to over 5,000 workers dying worldwide every day. There are an estimated 500-2,000 non-fatal injuries for every fatal injury, many of which result in lost earnings, lost jobs and permanent disability and poverty.
1.3 The human and social cost of work-related accidents and illness should not be
underestimated; for every person injured or killed there are also families, friends, and communities who must cope with the physical, psychological and economic consequences.
1.4 The business impact of workplace accidents and ill-health is also compelling – in
addition to the direct costs of sick pay and absence, employers can find themselves dealing with criminal prosecution, claims for compensation, adverse publicity and harm to both business reputation and profitability. In the UK alone the estimated annual cost of occupational injury and illness is £5 billion (around US$10 billion) to employers and £16 billion (over US$30 billion) to the British economy. The annual worldwide cost of occupational injury and illness is estimated by the ILO to be US$1,000 billion.
1.5 Management of health and safety in the workplace makes sound business sense.
Qualified health and safety practitioners are an asset to their organisations, reducing costs by preventing accidents and ill-health of workers, without incurring unnecessary expense by over-reacting to trivial risks. The practical approach of the NEBOSH International Diploma promotes the application of the knowledge acquired on the course to problem solving in the candidate’s own workplace.
1.6 There is considerable flexibility in the modes of study for the NEBOSH International
Diploma to enable a programme of study to be tailored to the needs of candidates and employers. Course providers run part-time day and evening courses, full-time block release courses and open/distance learning courses in accordance with the mode/s of study that are covered by the accreditation by NEBOSH. Many can also organise in-house courses to meet the needs of individual employers. A list of course providers for the NEBOSH International Diploma is available from NEBOSH or may be accessed from the NEBOSH website (www.nebosh.org.uk).
1.7 Candidates should be conversant with the main requirements of recognised
international standards as they apply generally to the workplace. An extremely useful source of reference in this respect is the “ILO Encyclopaedia of Occupational Health and Safety” (4th edition, ISBN 92-2-109203-8), although this is too lengthy to recommend as a course text.

Guide to the NEBOSH International Diploma in Occupational Health and Safety
ILO Codes of Practice, UK Health and Safety Commission (HSC) Approved Codes of Practice and HSE guidance publications, as well as many US Occupational Safety & Health Administration (OSHA) publications (e.g. the OSHA Manual), may also provide a guide for both tutors and candidates to much of the material covered by the syllabus, although candidates will not be expected to be conversant with every detail of such publications. Candidates should be guided by their tutors on the extent to which reference could usefully be made to the materials identified, which may depend partly on the comprehensiveness of course notes.
1.8 NEBOSH is committed to the continued development of qualifications and is working
closely with the university sector in gaining acceptance of the NEBOSH qualifications as prior learning for parts of MSc programmes.

2. Structure and rationale of the qualification 2.1 Background
2.1.1 All health and safety practitioners need to have a common core of knowledge in
order to practise effectively. This common core of knowledge is essential to all and is in essence transferable between the different occupational sectors in which health and safety practitioners practise, which range across all parts of industry, commerce and the public sector. Increasing globalisation has seen the migration of manufacturing industry from established to emerging economies where health and safety standards may not be as well developed. Multinational companies, particularly those in mineral and oil and gas exploration are increasingly seeking to adopt harmonised health and safety standards wherever in the world they operate. Health and safety practitioners need to be equipped to carry with them knowledge of the principles and practices of their profession wherever they may be engaged. This may cover working environments as diverse as, for example, a residential care home, an oil platform or a construction site. There is greater emphasis on emerging areas of increased risk such as stress and violence at work to reflect the need for developing competencies in these areas.
2.1.2 The NEBOSH International Diploma aims to provide the knowledge and
understanding that underpins competent performance as a health and safety practitioner and develop the ability to apply knowledge to a practical situation. This knowledge base is set out in Section 4: Syllabus for the NEBOSH International Diploma. With relevant structured experience, competence as a health and safety practitioner can be developed by applying this knowledge to the practice of occupational health and safety. The NEBOSH International Diploma is based on the NEBOSH National Diploma.
2.1.3 The original NEBOSH National Diploma, introduced in 1988, became the single most
widely taken academic qualification for occupational health and safety practitioners in the UK, with 3,614 people achieving it. NEBOSH sought to build on this success and saw the subsequent two-part NEBOSH National Diploma, introduced in 1997, not merely as a timely update of the syllabus but also as an opportunity to improve all aspects of the qualification, including its structure, content, delivery and assessment. To date, over 5,000 people have been awarded the Part 1 Diploma and more than 1,400 the Part 2 Diploma.
2.1.4 The International Diploma was first launched in pilot form in 2006 and was delivered
successfully by three course providers with the first examination in July 2007 . The results of the pilot and feedback from stakeholder consultation has led to this revised syllabus.
2.2 Standard of the qualification 2.2.1 The NEBOSH International Diploma has been designed to be assessed at the same
level as the NEBOSH National Diploma in Occupational Health and Safety. Although the NEBOSH National Diploma is a Higher Level (HL) Vocationally-Related Qualification (VRQ), the National Qualifications Framework (NQF) developed in England, Wales and Northern Ireland permits comparison with academic qualifications. The National Diploma is assessed at Level 6, equating to a Bachelor’s degree with honours within the Framework for Higher Education Qualifications (FHEQ).

2.3 Structure of the qualification 2.3.1 The unitised syllabus of the International Diploma is designed to allow flexibility and
continuity for those studying health and safety at this level. The arrangement of the content within each syllabus element has been modified to more accurately reflect the revised learning outcomes.
2.3.2 The structure of the qualification consists of three core units assessed by
examination (Units IA, IB & IC) and an additional workplace-based assignment unit (Unit ID), designed to test knowledge across the breadth of the International Diploma syllabus. This is intended to enable the assessment methods to reflect the practical application of skills learned during the course to the candidate’s workplace in a meaningful way, further increasing the benefit of the qualification to sponsoring organisations.
2.3.3 Candidates may choose to take all of the three examinations at the same sitting or at
different sittings. On successful completion of each of the units, a unit certificate will be issued. However, in order to achieve the NEBOSH International Diploma qualification, candidates will need to pass each of the four units.
2.3.4 The syllabus consists of preparatory content and four qualification units: Preparatory content: Core skills (communication and training) Qualification units: Unit IA International management of health and safety
Unit IB International control of hazardous agents in the workplace Unit IC International workplace and work equipment safety Unit ID International application of health and safety theory and practice
The structure and content of the units and elements are set out in Section 4: Syllabus for the NEBOSH International Diploma.
2.3.5 The total study time for each unit is as follows: Preparatory content: Core Skills: 10 hours tuition and 9 hours private study Total: 19 hours Qualification units: Unit IA: 95 hours tuition and 75 hours private study Total: 170 hours Unit IB: 65 hours tuition and 50 hours private study Total: 115 hours Unit IC: 65 hours tuition and 50 hours private study Total: 115 hours Unit ID: 6 hours tuition and 50 hours private study Total: 56 hours A programme of study therefore needs to be based around a minimum of 241 taught
hours and approximately 234 hours of private study.

Guide to the NEBOSH International Diploma in Occupational Health and Safety
2.4 Core Skills 2.4.1 The preparatory content covers the core skills of communication and training that
candidates will need to complete all four qualification units. While not assessed separately, assessment of these core skills is incorporated across the syllabus as part of the written examinations (Units IA, IB & IC) and the written assignment (Unit ID). Core skills should be presented as introductory content at the beginning of the programme and internally assessed by the accredited course provider in order to determine whether the candidate is adequately prepared to progress to the qualification units.
2.4.2 Some candidates may require additional support in the development of basic skills to
help them to achieve the learning outcomes of the preparatory content. Similarly, some candidates may be exempted from all or part of the preparatory Core skills content, for example, those in possession of the NEBOSH Part 1 Diploma or those holding a degree or professional qualification. In order to gain exemption, candidates must be able to demonstrate to their accredited course provider that the relevant core skills (eg, research skills) have been addressed as part of prior learning.
2.5 Programmes of study 2.5.1 The study time will be used to benchmark the adequacy of a proposed programme.
Any variation to the normal contact time will need to be justified by an accredited course provider to the satisfaction of NEBOSH on the basis of reasonable provision to meet adequately the learning needs of a particular cohort. The same philosophy will enable distance or open learning programmes to be eligible for accreditation. The categories ‘tuition’ and ‘private study’ have in mind a face-to-face mode of programme delivery but they will provide a benchmark for candidates studying by supported open or distance learning. Such candidates should be guided by the total study time, which includes own study time and time spent in individual or group tutorials.
2.5.2 The treatment of health and safety law in the syllabus has been arranged such that
legal principles are covered within Unit IA. Health and safety law is dealt with in a comparative manner and includes quasi-legislative approaches such as self regulation. The application of specific legislative requirements for individual jurisdictions is not included but students should be directed to identify the legal systems and enforcement in relation to health and safety which operate in their own jurisdictions. This may best be achieved by the inclusion by course providers of a formative assessment exercise in the teaching programme. This reflects the development and changing nature of both the health and safety profession and health and safety law, where the law is now seen to underpin, rather than to dictate, good health and safety practice.

3. Assessment and criteria for qualification 3.1 Entry requirements 3.1.1 The NEBOSH International Diploma syllabus assumes that candidates will have the
broad basic knowledge of health and safety equivalent to that given by the NEBOSH International General Certificate (IGC). While this is not mandatory, it should be noted that the syllabus content includes both knowledge expected of students, equivalent to having undertaken such a programme of study, and content that will have been covered in the IGC. For further details see page 14, note 1.
The achievement of the IGC or direct equivalent prior to undertaking the Diploma course is highly recommended, given the demands of this level of study, the time commitment required and the complementary nature of the NEBOSH IGC and International Diploma. Further information on the NEBOSH International General Certificate can be found via our website www.nebosh.org.uk.
3.1.2 Course providers should ensure that a candidate will benefit from studying at
Diploma level and in the mode and format in which the course provider offers the International Diploma. NEBOSH accredited centres wishing to apply Accredited Prior Learning (APL) arrangements to candidate selection are encouraged to do so. Further guidance for course providers regarding Accredited Prior Learning will be made available on request.
3.1.3 The standard of English required by students studying for the NEBOSH International Diploma must be such that they can both understand and articulate the concepts contained in the syllabus. There are a range of proficiency tests available for assessing English language skills. However, the most widely used in the academic and technical/professional environments is the IELTS (International English Language Testing System). This test is one of a series offered within the University of Cambridge’s ESOL (English for Speakers of Other Languages) Examinations. It is run in conjunction with British Council. In this subject, Cambridge ESOL is a recognised provider of training by the Office of Qualifications and Examinations Regulator (Ofqual).
There is a Common European Framework (CEF) for defining language skills. A high level (C1) is appropriate to a health and safety practitioner. The IELTS tests fit within this framework.
It is important to stress that the onus is on centres to determine their candidates’ standards of proficiency in English. However, the approach used in the IELTS system is a proven one and course providers are advised to satisfy themselves that their candidates are adequately prepared for a linguistically demanding programme of study.

3.1.4 Candidates will also need to demonstrate that they have access to facilities to enable
them to carry out the workplace-based assignment (Unit ID). It will be the responsibility of the accredited course provider to secure access to workplace(s) for those they accept on to a programme of study, who are, for example, not in employment or in an unsuitable work environment (e.g., a small, low risk office).
3.1.5 It should be noted that the qualification includes a requirement to write an extended
assignment (Unit ID). Candidates with limited experience of extended assignment writing may therefore require additional training in this skill if they are to complete the assignment successfully. Many candidates may not have been involved in study for some time and will require training and practice in both study and examination techniques.

3.1.6 Finally, if a potential candidate is considered suitable by a course provider, the provider should emphasise to the individual the demands of both Diploma-level study and the International Diploma itself, in particular the knowledge and understanding already assumed by the syllabus and the significant time commitment required to complete the qualification.
3.2 Assessment system for the NEBOSH International Diploma 3.2.1 The system of assessment for the International Diploma consists of three
examinations (Units IA, IB & IC) and a workplace-based assignment (Unit ID). All components are set and marked by NEBOSH. Candidates who achieve a pass standard in each of the three examination papers and in the assignment will be awarded the NEBOSH International Diploma in Occupational Health and Safety.
3.3 Examinations (Units IA, IB & IC) 3.3.1 NEBOSH sets a written examination paper of three hours’ duration for each of these
three units. Examinations will normally be held each year in the third full week of January and in the first full week of July unless prior notice has been given. Papers for Units IA, IB and IC shall be offered on the mornings of Tuesday, Wednesday and Thursday respectively.
3.3.2 The examination pass standard is determined qualitatively about a datum point of
45%. The examinations are set and marked in accordance with regulatory requirements and best practice. Guidance can be found on the NEBOSH website.
3.4 Assignment (Unit ID) 3.4.1 A workplace-based assignment (Unit ID) is set and marked by NEBOSH.
Submission dates for Diploma assignments are in March and September of each year. The assignment brief, assignment mark scheme and more detailed guidance on completing the assignment can be found in Section 5. Unit ID assignments will not be returned to candidates and please note that no feedback will be provided. Marks for re-submitted assignments are not capped.
3.4.2 Candidates must achieve a pass standard of 50% in the assignment in order to
satisfy the assessment criteria for the award of the International Diploma. 3.5 General regulations for the NEBOSH International Diploma qualification 3.5.1 To qualify for the NEBOSH International Diploma a candidate must: (i) enrol as a course member with an accredited course provider and, through the
course provider, with NEBOSH. Enrolment with NEBOSH (with payment of the appropriate fee) should normally be made at the beginning of the programme of study;
(ii) register with NEBOSH through a course provider as a candidate for the relevant
examination paper (with payment of the appropriate fee) when eligible to do so;
(iii) register with NEBOSH through a course provider as a candidate for the assignment unit (with payment of the appropriate fee) when eligible to do so;
July 2008

Guide to the NEBOSH International Diploma in Occupational Health and Safety
(iv) fulfil all other requirements as may be made from time to time by the accredited course provider and/or NEBOSH.
3.5.2 The period of enrolment with NEBOSH shall be five years. To be eligible to enrol on
a NEBOSH-accredited programme of study, candidates must satisfy any entry requirements specified by the course provider (see Section 3.1: Entry requirements). Acceptance onto a programme of study may also be based on the admission tutor’s judgement on the candidate’s ability to benefit from the programme. All candidates will be required to complete the preparatory Core Skills content unless they possess a qualification, such as NEBOSH Diploma Part 1 or a degree level qualification that may give exemption from the whole or part of this content. In order to gain exemption, candidates must be able to demonstrate to their accredited course provider that the relevant core skills (eg, research skills) have been addressed as part of prior learning.
3.5.3 Students must satisfactorily complete all four units within their enrolment period (five
years). 3.5.4 Candidates who have reached the end of the enrolment period but still wish to
complete outstanding units may apply for a single one year enrolment extension. These are considered by NEBOSH on a case-by-case basis. Successful applications for the enrolment extension will incur a fee.
3.6 Assessment results 3.6.1 Examinations
NEBOSH will determine a percentage mark for each candidate in each of the assessed unit examinations. Candidates who have been referred in an examination and who wish to re-sit must (i) complete the appropriate registration form, and (ii) send the form, together with the re-examination fee, to reach NEBOSH by the due date.
3.6.2 Assignment
NEBOSH will determine a percentage mark for each candidate in the assignment unit.
Candidates who have been referred in the assignment and who wish to re-submit must (i) complete the appropriate registration form, and (ii) send the form, together with the re-submission fee, to reach NEBOSH by the due date.
3.6.3 Unit grading and certification
The examination pass standard is determined qualitatively about a datum point of 45% for the written papers (Units IA, IB, and IC) and 50% for the assignment (Unit ID). Candidates who are successful in an individual unit will be issued with a unit certificate, normally within 8 weeks of the issue of the unit result notification. This will show a pass grade only.
3.6.4 Qualification grading
July 2008
10
Guide to the NEBOSH International Diploma in Occupational Health and Safety
When candidates have been awarded a unit certificate for all four units (ie, have achieved a Pass in Units IA, IB, IC and ID), the marks for all four units are added together and a final grade is awarded as follows:
Pass 185 - 239 marks Credit 240 - 279 marks Distinction 280 marks or more 3.6.5 Qualification certification
Once a candidate has achieved at least a Pass grade in all four units and the overall qualification grade awarded, a qualification parchment will be issued, normally within 8 weeks of the issue of the result notification. A candidate may opt to resit a successful unit in order to improve their grade at any time during their enrolment period. Once the result of the fourth successfully completed unit has been issued the candidate has one month from the date of issue of that result to either: • inform NEBOSH in writing of their intention to re-sit a successful unit for the
purposes of improving a grade or; • submit an Enquiry About Result (EAR) request (see 3.11.2 below). Candidates who fail to do this will be issued with a qualification parchment and will be deemed as having completed the qualification.
3.6.6 Unit re-sits If a candidate’s performance in any unit component is lower than a pass, candidates may re-register and re-sit just the component/s in which they have been unsuccessful providing that they re-sit within the 5 year enrolment period. However, each re-sit will incur an additional fee. Candidates may re-take units at any time within their enrolment period, including where they have passed and wish to re-take to improve their grade. Once all four units have been successfully completed, candidates will need to inform NEBOSH of their intention to re-take within one month of the date of issue for the fourth unit result. (See 3.6.5). There is no limit to the number of re-sits within the enrolment period. If a re-sit results in a lower mark than a previous result for that unit, the highest mark will be retained. For the Unit ID assignment, there is no limit to the number of submissions within the enrolment period. If a candidate gains lower than a pass in the assignment, they may revise and submit the assignment again. However, they must re-register for the assignment in order to do so. Please note that no feedback will be given on the referred assignment (see 3.4.1) and each additional submission will incur a fee. Marks awarded for subsequent submissions will not be capped.
3.6.7 NEBOSH adopts rigorous procedures to ensure that all examination scripts are
marked to a consistent and reliable standard. Following pre-standardisation marking of sample scripts by qualified Examiners, a standardisation meeting of all Examiners is convened where the final mark scheme is agreed. This is then followed by total
July 2008

Guide to the NEBOSH International Diploma in Occupational Health and Safety
marking/re-marking of scripts to the standardised scheme. Each Examiner’s results are qualitatively and quantitatively reviewed in order to ensure that the standard is consistently maintained. Careful consideration is given to those candidates who have received borderline marks and to any special considerations (see section 3.10) before the final declaration of results.
3.7 Examinations arrangements 3.7.1 It is NEBOSH policy that, in order to maintain a consistent and equitable standard in
the conduct of its examinations, these shall be conducted only at a NEBOSH-approved examination course provider.
3.7.2 Some UK-based accredited course providers offer courses and examinations outside
the UK. In addition, there are NEBOSH accredited course providers outside the UK. Further information is available in the ‘Where to Study’ section of the NEBOSH website.
3.7.3 Examinations at British Council offices
Course providers may arrange for their candidates to take the written examinations at a British Council office. The course provider will be responsible for making the arrangements directly with the appropriate British Council office. The location of the examination should be entered on the examination request form completed by the course provider.
3.7.4 British Council offices will levy a charge to course providers for the provision of
accommodation, invigilation and handling and despatch of examination materials on their behalf. The course provider must pay such charges directly to the appropriate British Council. The fees payable to NEBOSH do not cover these charges; nor are such charges recoverable by course provider or candidates from NEBOSH.
3.7.5 Languages Examinations are normally offered in English; however they may be available in languages other than English. Candidates should contact the course provider who should liaise with NEBOSH. 3.7.6 Admission vouchers and proof of identity Before an examination, registered candidates will receive an admission voucher that
gives their candidate number and the regulations for candidates. The candidate number is the only identification that candidates may use on their examination scripts – scripts must not include the name of the candidate. The admission voucher is essential to gain entry to the examination room but the invigilator will require photographic proof of identity, for example: passport, driving licence or identity card.
3.8 Requests for reasonable adjustments 3.8.1 Reasonable adjustments are arrangements which are approved in advance of an
examination to allow attainment to be demonstrated by candidates with either a permanent or long-term disability or learning difficulty, or temporary disability, illness or indisposition.
July 2008
12
Guide to the NEBOSH International Diploma in Occupational Health and Safety
3.8.2 Requests for reasonable adjustments must be made to NEBOSH by examination course providers at least one month before the examination.
3.8.3 For further details see the NEBOSH “Policy and Procedures on Reasonable
Adjustments and Special Consideration” from the NEBOSH website or on request. 3.9 Requests for special consideration 3.9.1 Special consideration is a procedure that may result in an adjustment to the marks of
candidates who have not been able to demonstrate attainment because of temporary illness, injury, indisposition or an unforeseen incident at the time of the examination.
3.9.2 Candidates who feel disadvantaged due to illness, distraction or any other reason
during the examination must report this to the invigilator before leaving the examination room and request that their written statement, together with the invigilator’s comments on the statement, be sent by the course provider to NEBOSH.
3.9.3 Requests for special consideration must be made to NEBOSH by the examination
provider as soon as possible after the examination and no more than seven working days after the assessment.
3.9.4 For further details see the NEBOSH “Policy and Procedures on Reasonable
Adjustments and Special Consideration” available from the NEBOSH website or on request.
3.10 Enquiries about results and appeals 3.10.1 NEBOSH applies detailed and thorough procedures to review and check examination
results before they are issued. This includes a particular review of borderline results. It thereby ensures that the declared results are a fair and equitable reflection of the standard of performance by candidates.
3.10.2 There are, however, procedures for candidates or course providers to enquire about
results that do not meet their reasonable expectations. An ‘enquiry about result’ (EAR) must be made in writing within one month of the date of issue of the result to which it relates.
3.10.3 For details see the NEBOSH “Enquiries and Appeals policy and procedures”
document available from the NEBOSH website or on request. 3.11 Malpractice
July 2008

Guide to the NEBOSH International Diploma in Occupational Health and Safety
3.11.1 Malpractice is defined as any deliberate activity, neglect, default or other practice by candidates and/or course providers that compromises the integrity of the assessment process, and/or the validity of certificates. Malpractice may include a range of issues from collusion or use of unauthorised material by candidates, to the failure to maintain appropriate records or systems by course providers to the deliberate falsification of records in order to claim certificates. Failure by an accredited course provider to deal with identified issues may in itself constitute malpractice.

4. Syllabus for the NEBOSH International Diploma This section sets out the full syllabus for the NEBOSH International Diploma in Occupational Health and Safety. The Diploma requires a total of 241 hours of tuition and about 234 hours of private study (including the Unit ID assignment). For candidates studying by open or distance learning, the duration of tuition and private study (shown in the tables preceding each unit) is additive to give the minimum recommended hours for this form of study. This includes own-study time and tutorial time. Notes 1 Recommended prior learning Before enrolling on the International Diploma programme it is strongly recommended that students should have successfully completed a relevant qualification in health and safety, such as the NEBOSH International General Certificate in Occupational Health and Safety. While this is not mandatory, the areas highlighted in BLUE in the syllabus content represent knowledge expected of students, equivalent to having undertaken such a programme of study. This does not imply, however, that these parts of the syllabus should be omitted entirely from a Diploma programme. Understanding of these topic areas should be confirmed, possibly by a simple test, and appropriate direction given to ensure that students are adequately prepared for continuing study in the relevant area. This may, for example, constitute directed reading, issue of revision notes or a brief revision session supported by additional reading material as appropriate. The areas highlighted in RED indicate content that will have been covered in a level 3 pre-entry course of study but where knowledge and understanding will need to be further developed in line with the level 6 standard (see note 2 below). The minimum tuition hours for each syllabus element are those required to cover the level 6 material learning (as highlighted). The areas highlighted in GREEN indicate changes to the International Diploma syllabus following evaluation of the pilot qualification. 2 Depth of study The depth of study required is indicated by the ‘command words’ within the syllabus content and by the recommended taught hours for each element.

5. Unit ID: International application of health and safety theory and practice 5.1 Assignment Brief 5.1.2 The candidate is required to carry out a detailed review of the health and safety
performance of a workplace or organisation and produce a management report including a justified action plan to improve performance.
5.1.3 The assignment will require the candidate to apply the knowledge and understanding
gained from their studies of elements of Units A, B and C in a practical environment and to carry out critical analysis and evaluation of information gathered during the review. The level of work should be that expected of a health and safety practitioner working within an organisation.
5.1.4 The report should include:
• A description of the chosen workplace/organisation to set a context for the assignment. The candidate will need to consider any regulatory framework within which the workplace/organisation operates;
• An overview of the current health and safety management arrangements in which
the candidate should critically review the health and safety management system;
• A survey of a wide range of significant hazards within the workplace. The candidate should prioritise the identified hazards and, depending on the nature and extent of identified hazards, for each of two of the hazards, one physical and one appropriate to health and welfare, carry out a risk assessment. This should include an evaluation of the effectiveness of the organisation in controlling the risks arising from the hazards identified and proposals to further control the hazard(s) and reduce risks;
• Conclusions which summarise the main issues identified in the candidate’s work
together with justified recommendations for improvement;
• A costed and prioritised action plan for the implementation of the candidate’s recommendations in each of the two areas;
• An executive summary of the report.
5.1.5 The accompanying guidance (see Section 5.2) provides information on how the
areas of the assignment brief are linked with the content covered in the taught units together with guidance on how to write the report. The guidance should be read carefully in conjunction with the mark scheme (see Section 5.3) to provide a clear guide to the requirements for the assignment report.

5.2 Detailed candidate guidance for Unit ID 5.2.1 The focus of the Unit ID assignment should be the application of the knowledge and
understanding developed in Units IA, IB and IC. It provides opportunities for the candidate to carry out research appropriate for a qualification based on a level 6 qualification. The assignment is designed to assess the ability of the candidate to apply the knowledge and understanding gained in the International Diploma course to a real workplace situation. Candidates are required to demonstrate the ability to carry out a range of activities that would be expected of a health and safety practitioner. This guidance sets the scope and expected level of work. Additional guidance is available in the Currently Studying section of the NEBOSH website.
5.2.2 The aim of the assignment is to produce an overall review of the health and safety
management system of an organisation and indicate, using a risk assessment, the priorities for the organisation for the future.
5.2.3 This guidance is intended to provide further information on what should be included
in the assignment report. Candidates should use the guidance, plus the further information available in the mark scheme, to guide them in the development of their assignments. It includes cross referencing to the relevant Elements of the Diploma Guide (See Section 4).
5.2.4 There are many detailed general guides to writing reports available on the internet,
often as part of study guides produced by university departments. A search under “writing reports” will produce links to such sites. It is strongly recommended that candidates study such material in order to understand how to write a report to the required standard for the assignment.
5.2.5 The assignment should include the following:
1. Introduction The assignment should be introduced with an overview of the organisation selected. It should include a general view of what the organisation does. This should include a description of what processes are undertaken, the employment profile, the work pattern employed and, if a department or site has been chosen in a very large organisation, its relationship to the work of the organisation. It is important to ensure that the choice of workplace provides sufficient scope (in terms of processes and activities) in order to match the expected depth of interpretation required by the International Diploma. However, candidates are advised to restrict the scope of the chosen workplace to make sure that the work is manageable and can be completed within the expected word count. The overview should include sufficient detail to enable the Examiner to gain an understanding of the workplace environment.
2. Regulatory framework
A summary of the legal framework (criminal, civil, self-regulatory etc) requirements within which the organisation operates (IA7) should be included. The purpose is to enable candidates to demonstrate their knowledge and understanding of the relevant legal frameworks (governmental and non-governmental) and most importantly the ability to put these in the context of the development of an effective health and safety management programme. There is no expectation for candidates to name specific pieces of legislation.
July 2008

Guide to the NEBOSH International Diploma in Occupational Health and Safety
3. Health and safety management system
The candidate should provide an overview of the health and safety management arrangements within the workplace (Element IA1). This should include a description of the health and safety management system, however informal it might be. This should be based on the procedures outlined in HSG65, BS 8800, OHSAS 18001, ILO-OSH-2001 or AS/AZ 4360, carrying out an initial status review of the health and safety management system and a gap analysis (i.e., ‘where are we and where do we want to be?’).
4. Identification and discussion of hazards
The candidate should identify and discuss the full range of principal hazards within the identified organisation (Unit IB). All workplaces involve hazards, the exact nature of which will depend on the nature of the workplace and the activities carried out there. Candidates should identify at least 15 relevant hazards using knowledge and understanding gained in Units IB and IC as a starting point. In order to cover a sufficient range, the identified hazards should be from across the following range of categories: chemical, physical, biological, psychosocial, ergonomic, mechanical, electrical, fire and explosion and transport. The outcomes of this exercise will be used in comprehensive risk assessments of two of the hazards.
5. Risk assessment
The candidate must justify the hazards chosen. The risk assessment methodology chosen should be appropriate for each hazard identified and should link back to how the organisation controls risk overall – i.e., are the risks associated with the hazards already identified well or poorly controlled, which would show one type of failure, or are the hazards previously unidentified, which would show another type of failure. The methodology adopted in completing each risk assessment should be outlined, including reference to relevant publications, standards, Codes of Practice, other technical documents and standards. The risk assessment should include a review of the existing control measures and provide options for further action with reference to a hierarchy of control. The candidate should make use of any data available for any hazards which have already been quantified. If no data is available it is not essential to make measurements.
6. Conclusions
This section should provide a concise summary of the main points identified in the main body of the candidate’s report. The conclusions should not introduce new issues or additional relevant factors.
7. Recommendations
Should be based upon the points set out in the conclusions. Recommendations should be prioritised and justified by reference to the candidate’s assessment of the levels of risk posed by the hazards they have identified.
July 2008
91
Guide to the NEBOSH International Diploma in Occupational Health and Safety
8. Action Plans
The action plans should present actions to improve the health and safety management system, the health and safety culture/climate of the chosen workplace and to reduce the risks associated with the hazards the candidate has identified for the two risk assessments. The action plans should indicate the actions to be taken, the person(s) responsible, the likely cost and the timescale for the implementation of each action. A quality action plan also includes provision for review.
9. Executive Summary
This should be written after the candidate has completed the rest of the report but it should be inserted at the beginning of the report. An executive summary is written for a person who is not necessarily an expert in the field. The purpose of the executive summary is to provide a concise overview of the main points arising from the work and the main conclusions and recommendations arising from it that can be read in a short time to accommodate the schedule of a busy reader.
An executive summary should provide sufficient information to enable a busy senior manager to make a decision as to whether or not to read the full report. This should be no longer than one side of A4 using single-spaced Arial font (Size 11). 10% of the marks available for the executive summary will be deducted for text covering up to an additional one-quarter of a page and a further 10% for each additional quarter of a page submitted as part of the executive summary.
10. References
Sources of information used in the report should be fully referenced using either the Harvard or Vancouver system of referencing. Full details of how to do this are available from:
http://www.bournemouth.ac.uk/library/using/harvard_system.html http://www.libweb.anglia.ac.uk/guides/new_harvard.php http://www.blackwellpublishing.com/authors/reference_text.asp?site=1.
11. Word Count
The expected length of an assignment is around 8,000 words equivalent to 32 sides of single-spaced A4 using Arial font (Size: 11).

6. Appendices Appendix 1: Role description of occupational health and safety practitioners Clearly communicated expert advice from appropriately qualified health and safety practitioners is an essential component in defining the safety, health and welfare policies of employers, ensuring that high standards of occupational health and safety are achieved and maintained. Health and safety practitioners are known by a variety of titles, from health and safety practitioner or adviser, through to health, safety and environmental director, reflecting varying demands and levels of responsibility. They work across the full spectrum of industry and commerce, and in organisations varying in size from multinational corporations to small consultancies. Occupational health and safety practitioners may work with directors, managers and team leaders to ensure that an organisation complies with relevant legislation as a minimum standard. Understanding and interpreting new legal requirements is often part of the practitioner’s role. The challenge for health and safety practitioners is to keep on top of legal and other developments and work out what the implications may be, well in advance of having to implement changes. Practitioners may also advise on priority-setting for health and safety programmes. The work of health and safety practitioners should complement the health and safety responsibilities of other managers. Practitioners may act in an advisory capacity on occupational health and safety management policy at board level. At managerial and supervisory level, health and safety practitioners may advise on the implementation of remedial measures suggested by risk assessments. Particular responsibilities may include the development of safe working systems and procedures, carrying out or supervising risk assessments and health surveillance programmes, or the development and delivery of training. Working proactively, practitioners strive to promote a culture of safe working within an organisation, aiming to enhance workforce attitudes towards health and safety. Occupational health and safety is very much a multi-disciplined profession, with practitioners specialising in, for example, ergonomics, risk management, safety auditing or occupational hygiene. Depending on the industry, they typically need to combine technical or scientific expertise with effective management, problem-solving and communication skills. It is part of every health and safety practitioner’s role to know when to call in external assistance on specialist matters beyond his or her normal remit. Not all health and safety practitioners work full-time from within an organisation. Competent and experienced safety and health consultants may advise small and medium-sized enterprises (SMEs) on health and safety management, perhaps in support of personnel who deal with basic health and safety issues in low risk areas on a part-time basis. Health and safety enforcement officers operate from a similar skills base to practitioners within commerce and industry, but with additional competencies relating to law enforcement.

Appendix 2: The National Examination Board of Occupational Safety and Health (NEBOSH)
NEBOSH – The National Examination Board in Occupational Safety and Health – is a UK company limited by guarantee and a registered charity that was formed in 1979 as an independent examining board and awarding body. NEBOSH now offers a comprehensive range of vocationally-related qualifications designed to meet the health and safety training needs of all places of work in both the private and public sectors. NEBOSH publishes syllabuses for courses in occupational health and safety of two main types: a professional Diploma level – The NEBOSH International Diploma in Occupational Health and Safety – and a Certificate level – The NEBOSH International General Certificate in Occupational Health and Safety. NEBOSH also offers specialist qualifications - The National Diploma in Environmental Management, the Certificate in Fire Safety and Risk Management, the National Certificate in Construction Health and Safety and the International General Certificate in Occupational Health and Safety. NEBOSH sets and marks the examinations based on its syllabuses. The International Diploma is examined in December and July each year and also requires the satisfactory completion of an assignment. For the International General Certificate, ‘standard’ examinations are offered in March and September and ‘local’ examinations on any date required by accredited course providers. NEBOSH does not offer course providers but accredits centres (such as colleges and private training organisations) to offer programmes of study that prepare candidates for NEBOSH qualifications. As a recognised awarding body, NEBOSH assessment procedures are approved and monitored by the UK regulatory authorities (Ofqual, DCELLS and CCEA), to ensure that its awards meet rigorous quality standards and comply with the best practice of the assessment industry. NEBOSH maintains Investors in People (IIP) status and is also an ISO9001:2000 registered organisation. The NEBOSH Council includes nominees of the Institution of Occupational Safety and Health (IOSH), bodies of Further and Higher Education, and private sector training organisations. Organisations that nominate independent members to the NEBOSH Council include the Health and Safety Executive (HSE), ENTO (formerly the Employment National Training Organisation), the Environment Agency (EA), the Confederation of British Industry (CBI), the Trade Union Congress (TUC), the International Federation of Health and Safety Groups and the International Institute of Risk and Safety Management (IIRSM). It also includes a recent Diploma graduate representing the interests of NEBOSH candidates. Strategic management of NEBOSH is overseen by a group of nine members of the NEBOSH Council known as the Directors and Trustees, including at least two members nominated by Colleges of Further and Higher Education and at least two members nominated by private sector course providers. The Directors and Trustees always include the Chairman and Vice-Chairman of the NEBOSH Council, and by custom and practice, the Chairman of the NEBOSH Council has always been the Chairman of the Directors and Trustees, thus ensuring effective co-ordination between the two.

Appendix 3: The Institution of Occupational Safety and Health (IOSH)
Founded in 1945, the Institution of Occupational Safety and Health (IOSH) is a leading International professional body for health and safety practitioners. Membership is currently over 30,000. The Institution works to advance the health, safety and welfare of people at work, and those affected by work activities. Clearly communicated expert advice from qualified occupational health and safety practitioners is essential in defining employers’ health and safety policies, priorities and implementation strategies. But health and safety is not just the practitioner’s responsibility – it is part of everybody’s working life. IOSH is committed to promoting protection from workplace hazards at every level. The Institution works to promote excellence in the discipline and practice of occupational health and safety. It allows entry to appropriate categories of membership in recognition of technical and professional competence and experience, and provides facilities to maintain and enhance skills and knowledge. IOSH offers a range of support services and products to its members and affiliates: • A free technical enquiry service • A free monthly magazine (The Safety and Health Practitioner) • A biannual journal • Professional development courses and conferences • Health and safety training • A continuing professional development programme • Regional and specialist group networks, including one dedicated to international
members • Publications • A free legal helpline • Discussion forums on the IOSH web-site including one aimed at study support. Those studying for the NEBOSH International Diploma may find it useful to affiliate to the Institution. Affiliates may attend meetings of local IOSH branches, participate in seminars and conferences at discounted rates, use the technical helpline service and receive the monthly magazine, The Safety and Health Practitioner.

Appendix 4: Relationship of the International Diploma to the International General Certificate The NEBOSH International Diploma provides a mainstream professional qualification route for health and safety practitioners and is based on the NEBOSH National Diploma which is accredited by Ofqual, DCELLS and CCEA at Level 6 in the National Qualifications Framework (NQF). The NEBOSH International General Certificate (IGC) is a qualification for managers, supervisors and other non-specialists to enable them to discharge more effectively their organisational duties or functions with respect to occupational health and safety. It is based on the NEBOSH National General Certificate which is accredited at Level 3 in the National Qualifications Framework (NQF). It is not intended as a professional qualification for occupational health and safety practitioners. NEBOSH recognises that some holders of the NEBOSH International General Certificate may wish to progress to a professional qualification route, such as the NEBOSH International Diploma. While undertaking the IGC is not mandatory in order to enrol on the International Diploma, it is strongly recommended given the Diploma syllabus assumes knowledge equivalent to having undertaken such a programme of study. Information on the NEBOSH International General Certificate is available from the NEBOSH website (www.nebosh.org.uk) or on request. Holders of the International General Certificate who can demonstrate at least 5 years in a health and safety role are eligible to apply for entry to the grade of Technician (Tech IOSH) with the Institution of Occupational Safety and Health (IOSH). The IGC also satisfies the eligibility requirements for Associate Membership of the International Institute of Risk and Safety Management (AIIRSM). Holders of the International Diploma may apply for Graduate membership (Grad IOSH) of the Institution of Occupational Safety and Health (IOSH - www.iosh.co.uk), and on completion of a programme of Continual Professional Development (CPD) can achieve Chartered Safety and Health Practitioner status as a Chartered Member of IOSH (CMIOSH), the major UK professional body in the field. Chartered Member status reflects the competence demanded of professionals in health and safety management or leadership positions. The International Diploma is also accepted by the International Institute of Risk and Safety Management (www.iirsm.org) as meeting the academic requirements for full Membership (MIIRSM).
