The number of students with special educational needs (SEN) in mainstream education in Hong Kong has increased, but the lack of professional training for in-service teachers appears to impede the successful implementation of an inclusive education policy. This study aims to evaluate and reflect on the delivery of an in-service inclusive education teacher training course provided by a local teacher training institution. A total of 3,274 teachers took this course between 2007 and 2010. Students' responses to an exit questionnaire were used to assess the course. The attitudes of the respondents towards the aim, content, resources, effect and value of the course and the level of satisfaction were generally positive, and increased as it evolved over time. The practical aspects (e.g., case analysis, classroom level strategies, guest lecturers' sharing and group discussion) were appreciated most by respondents. The implications of the findings and suggestions for further improvement are presented and discussed.
