The archive holds the data of pupils in state-funded schools in England and, occasionally, of teachers and parents. Most evaluations we commission include randomised control trials (RCTs) to assess the impact of education interventions on pupils’ attainment and a range of secondary outcome measures. The archive also contains data from some QEDs, and we intend to extend the types of data held within as EEF expands to different types of evaluation and methodologies.

The type of data archived after project completion varies between projects, but for most evaluations, this includes primary outcomes, secondary outcomes, treatment allocation and any other variables used in statistical analysis (e.g., compliance, missingness, sensitivity, mediation analysis). Primary outcome measures are most often attainment measures, which vary depending on age group and type of intervention, but could be statutory assessment, like SATs and GCSE scores or commercial, validated tests, for example GL assessments. Secondary outcome measures may include proximal outcomes, or other attainment areas of interest.

You can find more information about the content of the EEF data archive in our new EEF data catalogue. The data catalogue contains information and metadata about the datasets and fields available for secondary research analysis. By clicking the ​“Resources” tab on each individual project page, you can also find low-fidelity synthetic datasets for most trials. Low-fidelity synthetic data can be used to facilitate understanding of what the data looks like, as well as to begin prepping analysis code. Find more about the creation of synthetic data here. We welcome feedback that could help improve the usefulness of these resources.
