This document outlines a policy for implementing Learning Action Cells (LACs) as a school-based continuing professional development strategy in the Philippines Department of Education (DepEd). LACs are intended to improve teaching and learning through collaborative problem-solving among teachers. The policy discusses establishing LACs to address identified needs, prioritizing topics like curriculum, assessment, and inclusion. LAC sessions are to be scheduled regularly to allow collaborative planning, implementation of interventions, and reflection on lessons learned to further develop teacher knowledge, skills, and student outcomes. Resources and norms are to be established to support effective LAC implementation at the school level.
