Interviews will be carried out with around 30 people whose work is linked to education policy in Wales. These interviews will be used to get an understanding of what people think about the role of schools in health and well-being; what they think the reform will look like in practice; and how to evidence whether the new curriculum has been successful. We will also measure the health and well-being of pupils that have not received the new curriculum, and from this set-up a group of pupils to compare and contrast against pupils who receive the new curriculum in the coming years. More interviews with school staff will help us understand how the new curriculum might achieve its aims for young people, schools and wider society. We will then bring all the findings together, to develop a picture of how the curriculum is expected to work. This will inform its implementation and how it will be evaluated. At the end of the fellowship, we will apply to a research funder to do a large evaluation of the reform. Public Involvement and dissemination Non-academic partners and the public, including school staff, policy partners, and pupils’ parents, will be consulted throughout this fellowship. The research is accompanied by a strategy for communicating findings to all of the people that might benefit. As well as publishing in scientific journals, we will make booklets and use social media channels such as Twitter, and webinars with school staff to reach wide audiences. A group of young people will advise us throughout the study.
