The tools designed by the researcher were created to collect data required for the investigation. The results of the study are the following: the level of participation of teachers is very high on the leadership and governance, curriculum and instruction, accountability and continuous improvement, and management resources; the level of teacher’s empowerment with regards to autonomy is high by most teachers and were very high on the collaboration, decision-making involvement, and mentorship; the extent of teaching effectiveness showed very high or strongly agreed relative to clear objectives, subject knowledge, engagement, and technology and integration. Statistical analysis showed a significant relation to the teaching staff in terms of empowerment and effectiveness through the guidance and usage of the SBM program in the school. There is a significant relationship between teachers’ participation in SBM on teachers’ empowerment and effectiveness, thus the hypotheses are both rejected. This concludes that there is enough evidence of the teacher’s participation to teacher empowerment and teaching effectiveness as influenced by the SBM principles in the schools. This study recommends maintaining the implementation of programs and activities to enhance and improve the overall performance of the schools. The principal or the school heads of the public elementary schools should implement programs with strong connections and involvement of the parents and stakeholders. This will help the school to achieve and maximize the potential of the students and the teachers. The teachers must continue their active participation in the SBM so that it becomes their best practice, and the school has maintained its quality which benefits among their students. Opportunities for professional development and training for teachers are still needed and provided by the SBM.
