Description
Summary:The Test of Gross Motor Development is among the most commonly used measures of gross motor competency in children. An important attribute of any developmental assessment is its sensitivity to detect change. The purpose of this study was to examine the instructional sensitivity of the Test of Gross Motor Development-third edition (TGMD-3) performance criteria to changes in performance for 48 children (age 4-7 years) with and without Down syndrome following 10 weeks of physical education. Paired t tests identified significant improvements for all children on locomotor (p < .01) and ball skills (p < .01). These significant differences were associated with moderate to large effect sizes. SEM was low relative to the maximum raw score for each subtest, indicating high confidence in the scores. These findings provide evidence that the TGMD-3 is sensitive to change in performance for children with and without Down syndrome.
