Introduction

Ethiopia has embarked on a process of reforming its TVET-System. Within the policiesand strategies of the Ethiopian Government, technology transformation by using

international standards and international best practices as the basis, and, adopting,adapting and verifying them in the Ethiopian context is a pivotal element. TVET isgiven an important role with regard to technology transfer. The new paradigm in theoutcome-based TVET system is the orientation at the current and anticipated futuredemand of the economy and the labor market.

The Ethiopia Occupational Standard (EOS) is the core element of the EthiopianNational TVET-Strategy and an important factor within the context of the NationalTVET-Qualification Framework (NTQF).They are national Ethiopia standards, whichdefine the occupational requirements and expected outcome related to a specificoccupation without taking TVET delivery into account.

This document details the mandatory format, sequencing, wording and layout for theEthiopia Occupational Standard which comprised of Units of Competence.

A Unit of Competence describes a distinct work activity. It is documented in a standardformat that comprises: Occupational title and NTQF level Unit code Unit title Unit descriptor

Elements and Performance criteria Variables and Range statement Evidence guide

Together all the parts of a Unit of Competence guide the assessor in determiningwhether the candidate is competent.

The ensuing sections of this EOS document comprise a description of the respectiveoccupation with all the key components of a Unit of Competence:
