This study compared performances and motor delay classifications for the Test of Gross Motor
Development-2nd edition (TGMD-2) and the Körperkoordinationstest Für Kinder (KTK) in a sample
of 424 healthy children (47% girls) between 5 and 10 years of age. Low-to- moderate correlations (r
range = 0.34–0.52) were found between assessments across age. In general, both boys and girls
demonstrated higher raw scores across age groups. However, percentile scores indicated younger
children outperformed older children, denoting a normative percentile-based decrease in motor
competence (MC) in the older age groups. In total, the TGMD-2 and KTK classified 39.4% and 18.4%
children, respectively, as demonstrating very low MC (percentile ≤5). In conclusion, the TGMD-2
classified significantly more children with motor delays than the KTK and the differences between
children’s motor skill classification levels by these assessments became greater as the age groups
increased. Therefore, the TGMD-2 may demonstrate more susceptibility to sociocultural influences
and be more influenced by cumulative motor experiences throughout childhood. Low-to- moderate
correlations between assessments also suggest the TGMD-2 and KTK may measure different
aspects of MC. As such, it may be important to use multiple assessments to comprehensively assess
motor competence.
