Developing a model for effective large-scale continuous professional development (CPD) for teachers remains a significant obstacle for many governments worldwide. This article describes the development and evolution of Vital--a CPD program designed to enhance the teaching of information communication technology in state-funded primary and secondary schools in England.

The program encourages and responds to teachers' reflective practice matching the teaching and learning demands of the twenty-first century. (Contains 2 notes and 1 figure.)
