The Prep School Baccalaureate is an assessment framework designed for pupils in the middle and upper years of prep schools. Rather than focusing solely on terminal examinations, it emphasises the development of core learning skills such as collaboration, leadership, and independence. The framework is governed by a board of trustees and aims to provide a robust alternative to the traditional Common Entrance model. It provides senior schools with a comprehensive profile of a pupil’s strengths and character, ensuring a more holistic transition from primary to secondary education while maintaining rigorous academic standards.
