—— This study examined the supervisory practices of school heads and their relationship to teacher performance, while also identifying challenges in educational supervision. Data from survey questionnaires provided valuable insights into the evolving leadership landscape. The demographic profile revealed that many school heads are younger, predominantly female, and professionally experienced, reflecting innovation, inclusivity, and gender balance. Teachers, on the other hand, were largely seasoned professionals with extensive service years and advanced degrees, signifying institutional stability and a culture of continuous learning. Findings showed that school heads consistently demonstrated effective supervision across six domains, with an overall mean of 3.10 (SD = 0.70). They excelled particularly in data analysis, monitoring, and professional development, highlighting their commitment to evidence-based leadership. Correlation analyses revealed significant positive relationships between the professional attributes of school heads and the effectiveness of their supervisory practices, as well as between teachers’ qualifications and their IPCRF performance. These results underscore the importance of experience, education, and continuous training in enhancing instructional and supervisory effectiveness. Despite these strengths, challenges such as managing diverse learner needs, curriculum changes, and adapting to leadership roles remain. These findings emphasize the necessity for adaptive, inclusive, and research-informed leadership. The study concludes that collaboration and professional growth between school heads and teachers are key drivers of school excellence. It recommends sustained capacity-building programs, strengthened data literacy, and improved performance management systems to ensure effective leadership, promote inclusive education, and enhance teaching outcomes in the Philippine educational system.
