This study was conducted to examine the Fundamental Movement Skills (FMS) levels of male students with intellectual disabilities between the ages of 10 and 18 years old. A total of 126 students with intellectual disabilities (IQ < 50), who were attending special education schools in South Korea, participated in the study. FMS were assessed using the Test of Gross Motor Development 2nd edition (TGMD-2), which evaluates locomotor skills (running, hopping, leaping, sliding and jumping) and object control skills (overhand throwing, catching, kicking, hitting, striking and dribbling). Data were analyzed using descriptive statistics and ANOVA with 95% confidence intervals, and the level of significance set at p < 0.05. The results showed that the older students had significantly better scores on all locomotor and object control skills except kicking. Higher proportions of students demonstrated mastery of performance criteria for the subset of locomotor and object control skills that involved only leg or arm movement, than for the subset that required coordinated body and arm movement.
