This document provides an overview of the Test of Gross Motor Development - 2nd Edition (TGMD-2), which measures gross motor skills in children ages 3 to 10 years. The TGMD-2 assesses 12 skills across two subtests of locomotor skills like running and galloping, and object control skills like throwing and catching. It takes 15-20 minutes to administer and uses common equipment like balls and bean bags. The TGMD-2 has good reliability and validity for assessing gross motor skills in typically developing children as well as those with conditions like cerebral palsy or autism spectrum disorder.

3. Introduction
 Measures HOW children coordinate their trunk and
limbs, rather than assessing the end result
 Quality of movement
 Ages 3 through 10
 12 gross motor skills
 PT, OT, or Adaptive PE
 15 to 20 minutes

4. Materials
 8 to 10-inch playground
ball
 4-inch lightweight ball
 Basketball
 Tennis Ball
 Soccer Ball
 Softball

 Object Control
 Two-hand strike of a
stationary ball

**TGMD-3 tasks

6. Structure: Scoring
 Each gross motor skill (12) includes a list of specific
performance criteria
 Represent a mature pattern of the skill
 If done correctly – score of 1
 If done incorrectly – score of 0
 2 Trials
 Subtest Raw Score (60) Subtest Standard Score
Gross Motor Quotient Percentile Ranks and Age
Equivalents

7. Who?
 Ages 3 to 10
 Kindergarten through 4th grade
 Cerebral Palsy
 Developmental Coordination Disorder
 Visual Impairment
 Autism Spectrum Disorder
 GMFCS level I-IV

8. Statistics
 Good Internal Consistency (alpha = 0.71-0.72) Houwen, 2007
 If alpha is too high, the items are almost redundant
 If alpha is too low, the items are very broad and
essentially unrelated
 High Inter-rater, Intra-rater, and Test-Retest
Reliability (ICC = 0.82-0.95) Houwen, 2007
 High Correlation between object control subtest
and the ball skills subtest of the Movement ABC

9. Pros Cons
 Focus on quality of
movement
 Developmental Skills
 School Participation
 Time to administer
 Group testing
 Easy to score
 Amount of equipment
 Novel tasks
 Cultural Differences
