Test Development
 1979 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 Standardization
 Standardization
 Uniform procedures for administration & scoring
 Rules, number of trails, and time limits
 Scores are compared to age-based norms
 n= 1,520 examinees
 Ages 4 years of age to 21 years and 11 months of age
 Based on the Current Population Survey (Bureau of the Census, 2001)
 Standardized Populations: African American, Hispanic, White, & Other
 Item Bias Review
 Gender
 Ethnicity

Psychometric Properties cont’d
 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.

Pad.
 Cost of Complete BOT-2 Kit $837
Scoring
 Recording Item
Raw Score
 Convert Raw Score
to Point Score
 Make Notes and

Administration
 Computing Subtest

Interpretation and Results
 Gives 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 Occupation
 Education 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
