This document outlines a school-based action plan on values formation at Tupsan National High School for 2023. The plan has three phases. Phase 1 involves orienting teachers, catechists, and student leaders on values formation through various training activities from August to September 2023. Phase 2 includes crafting a student handbook, scheduling religion teaching, and holding recollection activities for parents and students from September to October 2023 to disseminate values. Phase 3 provides for ongoing evaluation and monitoring of the plan throughout the year. The overall goals are to intensify values formation of learners, reform student behavior, and minimize incidents of misbehavior through integrating values in all subject areas.
