The Test of Gross Motor Development, 3rd Edition (TGMD-3) is a process-oriented fundamental movement skill assessment to examine the movement patterns displayed by children between the ages of 3 and 10 years. Within this paper, results of a pilot study on the reliability, validity, and measurement invariance across gender of the TGMD-3 (German translation) are presented. In total, performances of 189 typically developing children (99 boys, 90 girls, 56 kindergarten children, 133 elementary school children, Mage = 7.15 ± 2.02 years) are analyzed. Results provide preliminary evidence for test-retest, interrater and intrarater reliability, internal consistency, age- and gender- specific performance trends, factorial validity, measurement invariance across gender, divergent validity, and ball skill–related concurrent and predictive validity of the TGMD-3 (German translation). Subsequent research should be focused on a verification of the present findings on a representative database to foster the application of the TGMD-3 (German translation) in different settings.
