Education Endowment Foundation

The Education Endowment Foundation (EEF) is a charity that aims to break the link between family income and education achievement. It supports schools, nurseries and colleges to improve teaching and learning for 2-19 year-olds through better use of evidence.

It was set up in 2011 by the Sutton Trust (a social mobility charity) in partnership with Impetus (a charitable funder focused on supporting young people from disadvantaged backgrounds), with a founding grant of £125m from the UK Government’s Department for Education.

In 2022, the government re-endowed the EEF with a further grant of £137m, to allow it to continue for at least another decade.

EEF is part of the UK Government’s network of “What Works” centres, which aims to improve the way that government and other public sector organisations create, share and use high-quality evidence in decision-making.

More detail about the Education Endowment Foundation

How does the Education Endowment Foundation work?

The Foundation works by:
  • summarising evidence. Reviewing the best available existing evidence on teaching and learning and presenting this in an accessible way – for schools, teachers, parents and others;
  • creating new evidence. EEF funding rigorous independent evaluations of programmes and approaches that aim to raise the attainment of children and young people from socio-economically disadvantaged backgrounds; and
  • putting evidence to use. Supporting education practitioners, as well as policymakers and other organisations, to use evidence in ways that improve teaching and learning.

How does the Education Endowment Foundation get new evidence?

The EEF funds the production of new studies to show what is likely to improve learning and educational attainment, especially for the most disadvantaged pupils. As confidence increases in the effect of an intervention, EEF scales up its delivery, whether in schools, nurseries or colleges. It works at with projects / interventions at four stages of development:

  • Pilot studies. These are conducted in a small number of schools, or early years / post-16 settings (e.g., three or more), where a programme is at an early or exploratory stage of development. They are evaluated through qualitative research to develop and refine the approach and test its feasibility in schools, nurseries or colleges. Initial, indicative data will be collected to assess its potential to raise attainment
  • Efficacy trials. These test whether an intervention can work under developer-led conditions in a number of schools, or early years / post-16 settings, usually at least 50. Impact is assessed using an independent and rigorous quantitative impact evaluation. At this stage, challenges to delivery are identified and an indicative cost of the intervention is calculated
  • Effectiveness trials. These test whether an approach can be delivered at such a scale that means the original developer does not need to be closely involved in delivery. These trial usually involve at least 100 schools or nurseries, across at least three different geographical regions. Again, a quantitative impact evaluation is used, challenges for delivery at scale are identified, and costs are calculated
  • Scale-up. This is when a programme which has been shown to work in a rigorous trial, and has the capacity to deliver at scale, is expanded to work across a bigger area delivering to a large number of schools, or early years / post-16 settings

The Good Giving List uses EEF’s effectiveness trials.

How does the Education Endowment Foundation assess impact?

EEF’s efficacy and effectiveness trials (evaluations) are mostly randomised control trials (RCT). This is where a group of settings (like schools) are allocated at random between:

  • a group that will run the intervention. This group is called the treatment group; and
  • a group that will not run the intervention. This is called the control group.

After the intervention, outcomes in the two groups (e.g., pupils’ learning levels) can be examined and statistically compared, to see whether there is any change, and if so, whether it is positive or negative. The comparison uses statistical techniques to see whether any differences in outcomes is simply down to chance or results from the intervention.

Using RCTs is not a guarantee of good quality evaluation – care is needed in how they are set up and evaluated. But when they are well done, they can be a reliable indication of the effects of a programme.
