Purpose: Combines fun activities with a reliable and valid procedure that gives meaningful results in identifying children with gross motor problems
Ages: 3-0 years through 10-11 years
Administration Time: 15 to 20 minutes
The TGMD-2, a major revision of The Test of Gross Motor Development, is a norm-referenced measure of common gross motor skills that can be used by kinesiologists, general and special educators, psychologists, and physical therapists. The TGMD-2 assists in identifying children 3-0 through 10-11 who are significantly behind their peers in gross motor skill development and who should be eligible for special education services in physical education.
The TGMD-2 is made up of 12 skills (six for each subtest):
- Locomotor: run, gallop, hop, leap, horizontal jump, slide
- Object Control: striking a stationary ball, stationary dribble, kick, catch, overhand throw, and underhand roll.
Detailed descriptions and illustrations of the gross motor skills and a simplified scoring system allow you to administer the TGMD-2 quickly and easily in 15 to 20 minutes. The TGMD-2 combines fun activities with a reliable and valid procedure that gives meaningful results in identifying children with gross motor problems. You can use the results of this assessment to develop instructional programs, monitor progress, evaluate treatment, and conduct further research in gross motor development.
Evidence related to content sampling and test-retest time sampling reliability is provided. Reliability coefficients for the Locomotor subtest average .85, the Object Control subtest average .88, and the Gross Motor composite average .91. Standard Error of Measurement (SEM) is 1 at every age interval for both subtests and 4 or 5 for the composite score at each age interval. Coefficient alpha for selected subgroups are all above .90 for the subtest and the composite. Time sampling reliability coefficients range from .84 to .96. Content-description, criterion-prediction, and construct-identification validity that further support the use of the TGMD-2 in identifying children who are significantly behind their peers in gross motor development are also provided.
Using the TGMD-2. you will obtain standard scores, percentile scores and age equivalents. The test also provides a Gross Motor Quotient if both subtests are completed.
Complete TGMD-2 Kit includes: Examiner's Manual and 50 Profile/Examiner Record Booklets in a sturdy storage box.
