This study investigates the effectiveness of a preparatory programme on the acceptance of students with physical disabilities by their peers in inclusive schools in Tehran. The classrooms which had students with physical disabilities were included in this study. Two hundred and twenty-one third- to fifth-grade students (116 girls and 105 boys) were selected randomly and were placed in experimental and control groups. The Acceptance Scale (Form B) established by Voeltz was used to measure peer acceptance. Data were collected from two groups before and after applying the preparatory programme. The data were analysed by t-test for independent groups and two-way ANOVA. The results showed increase of acceptance in experimental group. Also in comparing the level of acceptance in girls and boys, the results indicated that the acceptance in girls were more than boys. (Contains 3 tables.)
