This document outlines the Philippine Professional Standards for Teachers (PPST), which shifted from the previous National Competency-Based Teacher Standards (NCBTS) due to factors like K to 12 curriculum reform, ASEAN integration, globalization, and the needs of 21st century learners. The PPST aims to clearly define teacher career stages and expectations, engage teachers in continuous professional development, and provide a uniform measure for performance assessment, needs identification, and support. It comprises 7 domains and 37 strands that cover specific dimensions of teaching practice, with the goal of producing holistically developed Filipino graduates with values and 21st century skills.
