Scores on the Test of Gross Motor Development-2 (TGMD-2) in a Czech sample recruited from mainstream urban elementary schools were compared with the U.S. normative sample. 315 children participated (152 boys, M age = 7.1 yr., SD = 0.3; 163 girls, M age = 7.0 yr., SD = 0.3). Differences in raw score means and percentiles were evaluated, showing differences between the Czech and the U.S. normative samples. Standardized U.S. norms for the TGMD-2 should not be generalized to the Czech population without further study.
