CPD should focus on mastery and innovation to improve teaching. Effective CPD models include lesson study, coaching, research projects, and learning communities. Barriers to meaningful CPD include lack of time and an emphasis on compliance over growth. Schools should create conditions where teachers can thrive through purpose, challenge, autonomy, growth opportunities, and recognition. This involves developing an evaluative culture centered on intelligent performance review and tailoring self-directed CPD. Research-engaged learning communities can engage with and in educational research to continuously improve practice.
