The purpose of this study was to evaluate the effectiveness of an in-service training program and understand teacher's receptivity to curriculum change in physical education. A total of 183 primary school teachers were recruited as participants on a voluntary basis. They were asked to respond to a questionnaire about their receptivity to changes in the current physical education curriculum as well as their views on the effectiveness of a teacher development program that was organized by the Chinese University of Hong Kong. The results showed that the participants felt that in-service training was needed to equip them to implement a physical education program in line with the curriculum reform. The in-service training program was deemed to be practical and effective, bringing about good communication among school teachers, educational experts, and government curriculum officers. In terms of their receptivity to curriculum change, the participants generally had positive attitudes to the innovation and showed further support for the change after attending the program. The role of the principal and the need for school support for the reform are discussed in the concluding section. Copyright © 2004 Taylor & Francis Ltd.
