Developed by Bob Moon, this Blueprint and Toolkit provides the guidance and supporting resources for a programme of around 12–15 weeks’ duration and includes a detailed framework that can be adapted to the context of a particular country, region, district or school. It targets institutions wishing to implement school-based teacher development (SBTD) more rigorously to improve the performance of schools and raise the achievement of children and young people. The resource is available as OER and is, therefore, accessible to policy makers and other implementers of teacher development systems.
