Continuing professional development (CPD) helps teachers maintain and improve their knowledge, skills, and qualities through their careers. There are three main types of CPD learning: structured/active learning through interaction; reflective learning through independent study; and self-directed learning through individual activities like reading. An effective CPD process is self-driven, focuses on learning from experience and review, and includes both formal and informal learning to help set goals. Maintaining a CPD provides benefits like an overview of development, identifying strengths and gaps, and supporting career progression and applications. It is important to keep a learning log to record progress towards goals.
