This study investigated students' evaluations of a positive youth development program entitled Project P.A.T.H.S. (Positive Adolescent Training through Holistic Social program) in Hong Kong. The participants were 19,790 Secondary 1, 2 and 3 students who joined this program at the extension phase of the project. They were required to complete a subjective outcome evaluation form to indicate their perceptions of the program content, instructors, and effectiveness. Results showed that the students evaluated this program positively. Amongst the students in the three grades, Secondary 1 students evaluated the program most favorably whereas Secondary 3 students had the relatively least favorable evaluation. In addition, the program content and instructors accounted for approximately 35% of the variance in program effectiveness. The findings generally imply the successful implementation of this program in the community-based phase.
