Principals effectively supervised academics (above 90% completion rate) and created supervision schedules (88% completion rate). Room for improvement in academic supervision tools, currently at 89.33% completion rate. Based on interviews, academic supervision varies based on teachers' readiness. Educators reduce apprehension by being familiar with supervision. Teachers adapt to technological constraints by using basic media. Teachers and principals collaborate post-supervision to address issues. Some teachers participate in MGMP activities, while financial and geographical constraints limit others. Principals' supervision planning needs enhancements for consistent oversight. Overcoming obstacles like technological limitations is crucial. Post-supervision evaluations and follow-up procedures are effectively executed. More effort is needed to ensure all teachers have training opportunities to enhance their competencies.
