The purpose of this study was to assess validity and reliability of the TGMD-2 on Flemish children with intellectual disability. The total sample consisted of 99 children aged 7-10 years of which 67 were boys and 32 were girls. A factor analysis supported a two factor model of the TGMD-2. A low significant age effect was also found for the object control skill but not for locomotor ability. Furthermore, a significant difference was observed between the results of the children of the United States without intellectual disability and Flemish children with mild intellectual disability.
