The development of a positive youth development program for Secondary 1 to 3 students in Hong Kong is outlined here. The Full Program consists of 40 units per grade, 20 of which belong to the Core Program. Each unit takes 30 minutes of class time to complete. The major features of the program are as follows: (i) strong theoretical underpinnings, (ii) comprehensive and holistic coverage of youth development, (iii) an expected effective developmental outcome of the participating students, (iv) a happy and stimulating developmental process of the students, (v) flexible teaching schedules and combinations of program units, (vi) professional training for participating teachers and social workers, and (vii) rigorous quality assurance of the program product. The whole project will contribute significantly to the fields of youth development, whole-person education, and life and moral education.
