A central aim of the Education Endowment Foundation (EEF) is to improve knowledge and extend the evidence-base on what works to raise the attainment of disadvantaged pupils in schools in England. To achieve this, all EEF projects will be rigorously evaluated by independent experts in educational research. These evaluations will be funded by the EEF.

The impact of projects on attainment will be evaluated, where possible, using randomised controlled trials, with a linked process evaluation to understand the elements of successful delivery. Evaluations will be conducted by one of the EEF's independent panel of evaluators. The EEF takes a cumulative approach to evaluation whereby the size of evaluation, and therefore the number of schools or projects that we would require grantees to work with, will be determined by what we already know or whether there is a need to either pilot a new approach or demonstrate that an intervention can work at scale. In order to build capacity and maintain quality the EEF is developing resources for evaluators on aspects methodology and implementation.

We want to share our research about what works to raise the educational attainment of disadvantaged pupils. As projects progress, we will integrate the results of all of our evaluations into the summary of evidence for practitioners in the Teaching and Learning Toolkit. Sitting alongside the Toolkit and large-scale evaluations conducted by the EEF is the DIY Evaluation Guide, a resource for teachers and schools. It provides advice and guidance for teachers who want to improve the way they design and carry out small-scale evaluations of new strategies in their own schools.

Our website will feature evaluation reports and examples of approaches that work. We want to make our approach to evaluation rigorous and transparent. All our research can be accessed through the document library.

Consultation on EEF star-ratings

The EEF has developed a classification and accompanying procedure for judging the security and usability of findings from EEF evaluations. The ratings are intended to be an accessible means for practitioners to judge how much weight to place on a finding. The ratings are provisional and are currently undergoing a period of consultation. The EEF welcomes feedback and comments on how the ratings might be refined and improved. The deadline for comments is Friday the 7th of March. Please send any comments to camilla.nevill@eefoundation.org.uk. You can find the paper on the star-ratings here.
