The aim of this study was to examine how program leaders in the Norwegian Network of Health Promoting Schools managed, facilitated, and supported the development and implementation of the health promotion initiatives at their school. Two focus group interviews were conducted with 10 program leaders. The findings suggest that the implementation of the program was enhanced when the program leader was part of the school leadership group. The program leaders stated that the vision, aims, and content of the health promotion program were generally similar to those of their schools, making it easier for them to motivate teachers to participate. They also acknowledged the positive effect of learning through collaboration within schools and between schools in the network.
