This study investigated the features of autism by Kyoto Scale of Psychological Development 2001, in particular examining mainly first failure and final success items. 60 autistic students with intellectual disabilities participated. The results showed that their hands were not too sensitive to recognize the change of slight weight. Also, it was hard for them to explain correct answers using their own language. Moreover, to distinguish between smile and sorrow faces was a difficult task for them. These results seem to make contribution to their daily school education.
