This study was conducted in two secondary schools, one belonging to a public and the other belonging to a private school system, in Gilgit-Baltistan. The primary participants of this study were four teacher leaders, two males and two females. I selected them through purposive sampling. Moreover, two groups of students, two community members and two head teachers from both the schools were selected as secondary participants. I used the qualitative case study methodology to explore the practices of participant teachers in the classroom, school and community through in- depth interviews, focus group discussions and classroom observations. These multiple data sources allowed me to explore the practices of participant teachers in the three realms. The key findings of the study suggest that in their classrooms, participant teachers strive to promote in- depth student learning using student-centred teaching as well as innovative methods of teaching and building close relationship with the students. In the school, they develop a cooperative and collegial environment by changing the existing practices and taking new initiatives such as teamwork and support. In the community realm, they try to develop a good relationship among the school, parents and the wider community. They develop linkages between parents, youth, management and school and also participate voluntarily in social services in the community for community development. In sum, implications of these findings for teachers, school or system are presented as recommendations. Teachers should develop a shared learning culture among their colleagues and develop a collaborative culture in the school and the management should provide teachers with the skills and knowledge necessary for continued instructional improvement which ultimately, enhances student learning.
