Wales (United Kingdom) is on the path to transform the way children learn, with a new curriculum aimed to prepare its children and young people to thrive at school and beyond. The new curriculum for Wales intends to create a better learning experience for students, to engage teachers’ professionalism, and to contribute to the overall improvement of Welsh education. An education policy is only as good as its implementation, however, and Wales turned to the OECD for advice on the next steps to implement the curriculum. This report analyses the progress made with the new curriculum since 2016, and offers suggestions on the actions Wales should take to ready the system for further development and implementation. The analysis looks at the four pillars of implementation — curriculum policy design, stakeholders' engagement, policy context and implementation strategy — and builds upon the literature and experiences of OECD countries to provide tailored advice to Wales. In return, the report holds value not only for Wales, but also for other education systems across the OECD looking to implement a curriculum or to enhance their implementation processes altogether.
