This research assessed the relationship between school-based supervision and teacher quality anchored on the Philippine Standards for School Heads PPSSH and Philippine Professional Standards for Teachers (PPST) among selected public schools in the Tudela District . It aimed to determine how effective PPSSH and PPST-based supervision practices-such as planning and goal setting, classroom observation and feedback, teacher professional development and mentoring, monitoring and evaluation, and collaborative learning communities-contribute to improving teacher competence and instructional quality. Using a descriptive-correlational research design, the study gathered data from school heads and teachers through validated survey questionnaires. Statistical tools such as weighted mean and Pearson's r were employed to interpret the data. Findings revealed that both school heads and teachers strongly agreed that PPST-based supervision is effectively implemented across all domains, with the highest ratings in monitoring, evaluation, and collaboration. Similarly, teacher quality was rated highly evident, particularly in creating inclusive learning environments and developing contextualized lesson plans aligned with curriculum standards. The computed r-value of 0.15 with a p-value of 0.065 (at the 0.05 level of significance) confirmed a significant relationship between school-based supervision and teacher quality. Furthermore, best practices identified include peer coaching, Learning Action Cell (LAC) sharing, immediate post-observation feedback, and individualized professional development plans (IPDP). The study concludes that adequate, developmental, and PPST-aligned supervision directly enhances teacher competence and professional growth. It recommends strengthening mentoring systems, sustaining collaborative learning communities, and institutionalizing data-driven and supportive supervision practices to uphold teacher quality and improve learning outcomes.
