The purpose of this study was to examine the effects of visual supports on the performance of the Test of Gross Motor Development (TGMD-2) for children with autism spectrum disorder (ASD). Participants (N = 22) performed the TGMD-2 under three different protocols (traditional protocol, picture task card protocol, and picture activity schedule protocol). Gross motor quotient scores on the TGMD-2 were measured and statistically analyzed using a within-subjects repeated-measures ANOVA. Results indicated statistically significant differences between protocols, while post hoc tests indicated that the picture task card condition produced significantly higher gross motor quotient scores than the traditional protocol and the picture activity schedule. The results suggest that more accurate gross motor quotient scores on the TGMD-2 by children with ASD can be elicited using the picture task card protocol.
