Abstract
This study explores the management practices of school heads, teachers’ competence and performance of Non-School Based Management (SBM) schools in Region XII. Using a descriptive-correlational design with data triangulation to examine the management practices, teachers’ competence, and performance of non-School-Based Management (SBM) schools in Region XII schools, data from 26 school heads and 316 teachers, utilizing complete enumeration were collected. Data were analyzed using percentages, means, standard deviations and revealed that school heads’ management practices were rated outstanding, demonstrating effective leadership. Teachers’ competence was rated very satisfactory, highlighting the need for continuous professional development. The performance level of non-SBM schools was rated good/developing, indicating they are in the developmental phase of school-based management. Correlation analysis found no significant relationship between school heads’ management practices and school performance, nor between teachers’ competence and school performance.
