The Education Endowment Foundation (EEF) is an independent grant-making charity dedicated to breaking the link between family income and educational achievement. It uses existing research of ‘what works’ in education, to evaluate the most promising educational innovations and teaching approaches to address the needs of disadvantaged children in primary and secondary schools in England. The EEF provides independent and accessible information through the Teaching and Learning Toolkit, summarising educational research from the UK and around the world. The Toolkit provides guidance for teachers and schools on how best to use their resources to improve the attainment of pupils.
