Teacher performance has an influence on student achievement and the quality of schooling. It draws on a combination of competencies such as instruction, deep subject knowledge, classroom management, and clear communication. While early teacher preparation establishes the foundation for teaching, Continuous Professional Development (CPD) is essential for keeping pace with the ever-changing demands of education. This paper examines how Continuous Professional Development (CPD) shapes teacher effectiveness, drawing on a review of the literature and recent research findings. The evidence indicates that well-structured CPD initiatives can markedly improve lesson planning, instructional techniques, assessment practices, and teacher confidence. Improvements have been recorded among both in-service and pre-service, emphasizing the need for sustained professional learning to foster comprehensive teacher growth. However, a variety of challenges continue to prevent CPD from reaching its potential. There are hurdles to effective development; the training’s content often does not line up with what teachers actually need in their classrooms, there is a lack of support from institutions, resources are scarce, and access remains limited, especially in rural areas or settings where gender considerations are paramount. The paper also argues that CPD programmes should be knit into broader education policies, emphasize core teaching competencies, be attuned to contexts, and nurture practice. Moreover, inclusive strategies should be implemented to break down participation barriers and guarantee access. This shows that when well-organized and executed, continuing professional development (CPD) enhances teacher effectiveness and cultivates sustained progress. Embedding CPD as a well-supported element of teacher development is crucial for nurturing professional growth and raising learning outcomes across a variety of educational contexts.
