What works or what's worked? Evidence from education in the United Kingdom.

This paper deliberates the quality of existing evidence on educational school-based interventions aiming to improve pupils’ attainment. An overall picture as well as more specific examples derived from the “Sutton Trust-Education Endowment Foundation (EEF) Teaching and Learning Toolkit” will be discussed presenting different cases and versions of the Toolkit (Early Years Toolkit). The main sources of studies are meta-analyses and systematic reviews with quantitative data, where they have enough information for the calculation of effect sizes (ES). This is an ongoing project; so some representative finding will be discussed providing a best estimate of what is likely to be beneficial in a number of areas of educational practice
