Gross Motor Domains
Gross motor composite total: 26 items Body coordination: motor skills used with balance & coordination of
the upper and lower extremities Strength & agility: large muscle strength, motor speed, and motor
skills for maintaining body position for walking and running

Procedures
Testing procedures Standardized test: administered & scored according to specific
procedures Gross motor should be performed in an area 60 feet long 12 feet wide Determine hand preference: set a tennis ball on the table and ask the
examinee to pick up the ball and throw to you. Foot preference: place tennis ball on floor and instruct the examinee
to kick the ball Within each subtest the entire item set should be administered
regardless of the child’s age

Procedures
• Administration procedures• Structured• Can teach the item using pictures, physical
demonstration, or verbal instruction• Establish rapport• Administrative options:
• Complete form: most reliable measure of overall motor proficiency
• Short form: quick and easy overall measure & also used to determine the need for further assessment
• Select composites & select subtest: can administer only subtests or composites that are relevant to the client’s need but the complete form should be used for qualifying a client for special-education services or diagnosis such as DCD

Standardization
Sample: N=1520 12 groups of 4-21 year olds Sample tested in 239 sites within
38 states Based on the Current Population
Survey (Bureau of the Census, 2001) & the Twenty-sixth Annual Report to Congress (U.S. Department of Education, 2004)
Sampling goal to match US population: Sex Race/ethnicity (closely matched US
population) Socioeconomic status Geographic region
•Scores identify motor-skill deficits in individuals with mild to moderate motor control problems

Development
Started out as the BOTMP in 1978
2002 product survey identified less effective items within the test
New content focused on improving measurement among 4 & 5 year olds, and expanding coverage of fine and gross motor skills
Secondary goal Subtest more homogenous collection of activities
2005 final publication of the BOT-2
