The School Improvement Program (SIP) is a systematic effort aimed at improving learning conditions and achieving educational goals more effectively. The SIP uses a decagonal approach involving capacity building for teachers and leadership, community and student participation, improving school environments, enriching curricula, research, and school-based interventions. The goal is to improve school environments and student achievement. Lessons learned include the importance of coordination, using local wisdom, active learning strategies, conducive environments, and recognizing that small improvements are meaningful. Challenges include time for training, staff transfers, perceptions, lack of professionalism, and invisible change processes.
