The purpose of this session is to provide a lens through which the impact of taking a whole school approach to the development and embedding of cognitive education can be evaluated. As the number of schools undertaking the Thinking Schools journey increases, opportunities to research and evaluate are also developing. Through the Thinking Schools accreditation provided by Exeter University (TS@Exeter), there is clear evidence demonstrating the benefits of taking a whole school approach to the teaching of thinking. The growth of accredited Thinking Schools across the globe, make this school development journey a truly international venture. Schools and school systems in Ethiopia, Lithuania, Malaysia, Norway, South Africa, New Zealand, the USA, Ireland, Egypt, Nigeria, Dubai, India, Thailand, Australia, and the UK have all taken up the challenge of developing a cognitive approach to education. Festival attendees will gain a thorough understanding of how to develop as a Thinking School.
