Key CharacteristicsAge: 4 - 21 years and 11 months oldDomains: (Subtests)Fine Motor Precision
Draw, cut, or fold within a specific boundary
Fine Motor Integration Reproduce drawings of geometrical shapes that range in complexity Visual tracking with coordinated arm and hand movement
Manual Dexterity Speed and Accuracy, timed Reaching, grasping, and bimanual coordination with small objects
Upper-Limb Coordination Measures visual tracking with coordinated arm and hand movement Catching, dribbling, and throwing a tennis ball

Test Development1979 Original BOTMP created
BOTMP was separated into gross and fine motor.BOT-2 was created to analyze more specific components of
fine motor and gross motor. Evaluation of both items were compared and certain testing
items eliminated.BOT-2 expanded coverage of fine and gross motor skills. Improved measurement among 4 and 5 year olds.Extended norms through age 21. Improved item presentation. Improved quality of kit equipment.

Test Content- When updating the BOT-2, only functional items that were proven to test its subtest title with moderately high factor were kept.
Criterion- Concurrent with 1-2 studies; demonstrates adequate agreement with a criterion or gold standard measure
Construct (Internal Structure)- The BOT-2 uses a composite structure that distinguishes fine motor skills on the basis of the limbs and musculature involved in object manipulation related to functional activities.
Test Length/CostFine Motor Composite Form:
20-30 minutes to administer 10 minutes needed to prepare the testing area
Fine Motor Short Form 5-10 minutes to administer 5 minutes needed to prepare the testing area
Cost of Fine Motor BOT-2 Kit $515.00 Kit includes Manual, Supplemental Manual, Administration
Easel, Record Forms (25), Target, Shuttle Block, Balance Beam, Knee Pad.
Cost of Complete BOT-2 Kit $837

Interpretation and ResultsGives a good baseline for
strengths and weaknesses.
Can choose between subtests and use ones that apply the most.
When explaining to parents, first identify average to above average scores, then address the below average areas that can be improved with OT.
Areas of OccupationEducation participation
The fine manual control subtest of the BOT-2 is particularly useful in screening for academic readiness in young children.
Assessment Approach/Environment
Assessment Approach: Bottom up
Looks at components that are necessary for functional occupational performance during short activities (not specific occupations)
Environment: Educational Setting Rehabilitation center/Health
Care Setting Home
Frame of Reference / Measurement Concerns
Frame of References:Motor Control and Motor LearningBiomechanical and Rehabilitative
Measurement Concerns:Examinee inattention with test lengthPoor test environment Inability to establish rapport Examiner incompetency Substitute for the standardized toolsDifficult to use with children who have disabilitiesTest cost
