This document discusses effective approaches to continuing professional development (CPD) for teachers. It outlines that CPD requires significant investment and not all initiatives are effective, so it is important to focus on evidence-informed CPD. The key features of effective CPD according to research are that it is needs-based, differentiated for individual teachers, focused on improving student learning outcomes, and provides opportunities for teachers to apply their learning in the classroom. Effective CPD also includes sustained support from initial input through implementation, not just one-off training sessions, and allows time for teachers to learn, apply, and embed new strategies in their practice.
