Abstract
This study examined the level of understanding of public elementary and high school teachers in the Poona Bayabao South District, Lanao del Sur I, regarding the Philippine Professional Standards for Teachers (PPST), and how this understanding correlates with their teaching performance. Utilizing a descriptive-correlational design, the research focused on the seven domains of the PPST: Content Knowledge and Pedagogy, Learning Environment, Diversity of Learners, Curriculum and Planning, Assessment and Reporting, Community Linkages and Professional Engagement, and Personal Growth and Professional Development. Data were gathered using surveys and the Individual Performance Commitment and Review Form (IPCRF) for School Year 2023–2024. Results showed that teachers generally demonstrated a strong understanding of the PPST domains and received high performance ratings. However, statistical analysis indicated no significant relationship between teachers' understanding of the PPST and their performance. The findings underscore the need for contextualized and practical professional development programs, particularly in areas like ICT integration and learner diversity. A proposed professional development training design was developed to address these gaps and enhance the application of PPST principles in daily teaching practice.
