This research investigates the professional growth of physical education (P.E.) teachers in private schools in Lucena City and the nexus between professional development program factors and teacher performance. Given that teacher professional growth is essential in promoting content knowledge, pedagogy, and classroom management, the research assesses the ways in which P.E. students and teachers rate the effectiveness of professional development programs along four key variables: insights, goals, techniques, and practices, according to Sam Sims et al.'s theory of I/G/T/P. Conducting a descriptive research design, the research gathers data regarding teacher demographics, training experiences, and performance evaluations, in addition to student perceptions of teacher performance.
