Reflective teaching has emerged as a critical component of effective educational practice and professional development. Through systematic reflection on instructional experiences, teachers can evaluate their practices, identify strengths and weaknesses, and implement improvements that enhance student learning outcomes. Reflective teaching practices promote lifelong professional growth by fostering critical thinking, self-awareness, adaptability, and evidence-based decision-making. This study examines the relationship between reflective teaching practices and professional growth among educators in higher education and secondary schools. A mixed-method research design involving 580 teachers, educational administrators, and teacher educators was employed. Quantitative data were analyzed using descriptive statistics and multiple regression analysis, while qualitative insights were obtained through interviews, reflective journals, and classroom observations. Findings indicate that reflective teaching significantly improves instructional effectiveness, classroom management, pedagogical innovation, and professional competence. The study concludes that embedding reflective practices within teacher development programs can strengthen educational quality and support continuous professional growth.
