Identify Type of Assessment: Standardized norm referenced 

Cost:

Starter kit: $687.00

Test forms and reports: $1.40

Replacement manual: $3.50

Training: $193.20

Population: Children and youth aged 4 to 21 years who have developmental disabilities who are able to follow directions. 

Appropriate Settings:  Test area that is 60 feet x 20 feet, with no noise or distractions and a table and 2 chairs that are appropriate for the age of the client. 

Purpose of Assessment & Function(s)/Area(s) Assessed:

This is assessment is used by therapists (OT. SLP, PT), educators, and researchers. This assessment provides a comprehensive index of motor proficiency as well as separate measure of gross and fine motor skills. The long form is appropriate for educational placement decisions and the short form is a screening tool that can be part of a comprehensive battery.

Administration: Long form: 50-70 minutes, short form, 20-25 minutes. The test has 8 subtests with 5 to 9 items in each.  (1) Fine Motor Precision, (2) Fine Motor Integration, (3) Manual Dexterity, (4) Bilateral Coordination, (5) Balance, (6) Running Speed and Agility, (7) Upper-Limb Coordination, and (8) Strength. There are standard instructions and it is important that the client understands the task.

User Qualifications: College degree (undergraduate or graduate) for Level B

Materials Required: administration easel, record forms, stopwatch and tape measure, manual, booklet, and other small items such as pencils, pennies, penny box, string, balance beam, knee pad, peg board, pencils, scissors, cards, and tennis balls. 

Scoring Procedure:

Test yields total point scores, scale scores, composite standard scores, and percentile ranks. Four motor area composites (1) fine manual control, (2) manual coordination, (3) body coordination, and (4) strength and agility) establish total motor composite. Age equivalents above average and below average are determined, and performance is compared with age and gender norms. 

Psychometrics/Standardization: Reliability: Internal consistency reliabilities were high, and mean subtest reliabilities ranged from high 0.70s to low 0.80s. Composite reliabilities ranged from high 0.80s to low 0.90s. total motor composite reliabilities were in mid-0.90s, with short-form reliabilities in mid-0.80s. Test-retest reliability coefficients ranged from 0.69 to mid- to upper 0.80s, and interrater reliability coefficients ranged from 0.92 to 0.99.

Validity: Test manual provides factual evidence of validity in test content, internal structure, clinical group differences, and relationships with other motor skills.

Strengths: This assessment helps develop motor skills and can figure out if the client needs extra support in overall fine motor skills and overall gross motor skills. 

Weaknesses: This is expensive and it could be hard to pin point what the client needs support in because they could over compensate with their fine or gross motor skill which could lead their score to being average or above average.
