The purpose of this research was to determine the leadership management function, which is primarily concerned with people and social interaction, as well as the process of persuading others to achieve the organizations or common goals. The studys participants were 35 public secondary school teachers from the Division of Lagunas Fourth Congressional District. The study used a validated researcher-made questionnaire as the primary instrument for gathering data and information from the studys many subjects. As per the findings of the study, secondary public-school teachers assessments of their administrators leadership capabilities have a substantial association with their administrators performance competencies. As a result, administrators of public secondary schools may urge teachers to pursue and complete graduate degrees to advance their careers. Encourage teachers to participate in programs other than those run by the Department of Education for professional development, such as research festivals, short courses, seminars, and training, and other professional possibilities. Discuss and offer people the training and development they require to perform their jobs and reach their full potential. Different tactics for long-term mentorship and coaching should be included by school principals to support instructors, particularly freshly hired teachers. The Department head must be open to the suggestions of teachers under him/her to effectively derive the consensus of the teachers and come up with a better decision. Have regular open and honest two-way conversations about performance and assess the performance of employees consistently, equitably, and fairly and provide employees with feedback on how they are performing constructively and with respect. Ensure that developmental programs for aspiring school leaders attention to encouraging participants to develop strategies for balancing work and other aspects of their lives. Lead a positive workplace culture by example and role model the right values and behaviors. Also, scholarship grants should be provided to willing teachers so that many can pursue their graduate studies. Even the teachers organization with the initiative of the officers may propose financial assistance to those teachers to improve their teaching skills. A similar study should be conducted to verify the result of the study.
