The Teaching and Learning Research Programme (TLRP) was the United Kingdom's largest investment in education research. It was initiated in 2000, ended in 2011 and was managed on behalf of the Higher Education Funding Councils by the Economic and Social Research Council. The programme engaged 700 researchers in some 70 major projects. These covered all education sectors - from Early Years to Higher Education and Workplace Learning. The TLRP researchers work closely in partnership with practitioners to ensure the relevance and application of findings to policy and practice. Thematic work across the diverse range of projects enabled analysis of themes and the identification of 'ten principles for effective teaching and learning'.
