The purpose of this study was to compare attitudes of final year students in teacher preparation program and in-service physical education teachers toward including students with disabilities into regular settings between Hong Kong (HK) and mainland China (MC), and to further examine the influences of attitudes on development of adapted physical education program. Total 152 participants (53 4th year students and 43 in-service teachers) from HK, and 56 students from MC participated in this study.

For question #3, "Students with severe disabilities should be taught in separate classes (APE classes)", 77% (HK) and 85% (MC) agreed. The survey indicated that students from HK and MC thought special school and teachers with special training will provide better education for students with disabilities than general teacher. Survey results also indicated from question #13, "to be prepared to teach students with mild to severe disabilities, it is important that I receive training on activities that includes ideas on lesson planning for a variety of abilities levels", that 95.5% students from both HK and MC agreed and strong agreed on "need more academic preparation" for inclusion. There were no significant difference between 4th year students and in-service teachers on these items. Other results indicated that, in addition to government policies, attitudes and lack of special education training for current teachers
