Instructional Leadership, Administrative Support and School Performance: Their Relationship to Learners'achievements

School heads play important role in helping schools provide equitable, learner-centered quality education through various leadership approaches. This study investigated the levels of instructional leadership, administrative support, and school performance, and their relationship to learners’ achievements in the public secondary schools in Congressional District 1 of the Division of Cagayan. A descriptive–correlational research design was used involving 16 school heads and 279 teachers using validated survey questionnaire. Gathered data were analyzed using frequency counts and percentage distribution, weighted mean and Pearson r correlation. Instructional leadership and administrative support were rated very high-level indicating school heads’ strategic leadership, strong instructional supervision, efficient resource management and active partnership with stakeholders. School performance showed favorable results as evidenced by high promotion rates, very minimal failures, and low dropout rates. Learners’ achievements were consistently reflected in classroom awards, academic excellence and special recognitions- mostly in the district level with minimal participation in regional and national competitions. Significant positive correlations between instructional leadership and academic excellence were found while administrative support showed significant positive correlations between academic excellence and special recognition awards. However, no significant correlations were observed between instructional leadership and administrative support in relation to conduct- and attendance-based awards. This concludes, that strong leadership is essential in improving learning outcomes and co-curricular achievement, although behavioral and school performance outcomes may be influenced by other external factors. Hence, school heads should intensify enrichment opportunities, reinforce stakeholder collaboration, and implement targeted learner development programs to sustain academic success and broaden achievement in higher-level competitions.
