The subjects were recruited 98 students with disabilities in Seoul, Kyoung-Ki, Chung-cheung. The data were analysed using Rasch analysis to investigate unidimensionality and rating scale model. The 4 items out of SFA Part II were found to be misfts. The 18 items out of physical tasks, the 14 items out of cognitive/behavioral tasks in Part III were found to be misfit.
