In this latest episode, Sir Kevan Collins, the departing chief executive of the Education Endowment Foundation (EEF), is interviewed by Evidence Based Education’s Jamie Scott about his eight years in the role – taking the EEF from a small start-up with three employees (“and a decent bank balance”) to becoming a global leader in generating and using evidence to improve educational outcomes for children and young people. Sir Kevan discusses the appetite for such research among teachers and policy makers, the EEF’s successes and challenges, and identifies the top five changes he’d make as education secretary.
