EEF Research Papers

The EEF publishes open access research papers that cover the results of research projects based on the data stored in the EEF Data Archive. 

This data archive is a unique database of data from EEF-funded evaluations of education interventions. This data can either be collected directly from schools and pupils, or be accessed through the National Pupil Database (NPD).

The papers are not externally peer-reviewed. They are published electronically and are freely available online or through email distribution.

For each paper, we publish an 'EEF response', briefly setting out how we are using these analyses to inform our future work.

Teachers' engagement with research: what do we know? A research briefing

Authors: Matt Walker, Julie Nelson, Sally Bradshaw, Chris Brown 

Research Brief May 2019

This research briefing summarises findings from a nationally representative survey of schools and teachers, which investigated teachers’ research use. The survey was designed with reference to the principles adopted in an earlier 2014 study in which the National Foundation for Educational Research (NFER) and the Education Endowment Foundation (EEF) developed a Research Use Survey (RUS) (Nelson et al., 2017). The new survey took the most effective elements of the RUS, and augmented these with recent knowledge about research engagement and use. The findings are based on survey results from 1,670 teachers in England. The survey was administered between 19 September and 12 November 2017. 


Properties of commercial tests in the EEF

Authors: Rebecca Allen, John Jerrim, Meenakshi Parameshwaran, Dave Thompson

EEF Research Paper Series, No. 001, February 2018

EEF response: This study analyses some of the properties of major commercial assessments used by the EEF in large trials. We have used the results of this study to update some of the assumptions fed into sample size calculations and inform the choice of appropriate and cost-effective commercial assessments to be used as pre-tests. 


Standard Deviation as an outcome on interventions: a methodological investigation

Authors: Peter Tymms, Adetayo Kasim

EEF Research Paper Series, No. 002, February 2018

EEF response: In line with its goal of narrowing the attainment gap in England, the EEF is considering methods to monitor the differential effects that interventions might have on pupils of varying levels of ability. A change in the dispersion of outcomes of the intervention group would be indicative of differential effects. Based on the results of this study, the EEF updated its Analysis Guidance to request evaluators to report the standard deviations by trial arm before and after the intervention. 


Does the classroom level matter in the design of educational trials? A theoretical & empirical review.

Author: Sean Demack

EEF Research Paper Series, No. 003, May 2019

EEF response: This study examines some of the theoretical and empirical implications which account for how pupils are naturally organised in ‘classes’, which are in turn clustered within schools. The EEF recognises the contribution made by this study and invites evaluators to consider accounting for the ‘class’ clustering in their proposed designs. This paper provides suggestions of cases when this may be more relevant. Due to a limited number of studies included in this review, additional evidence is necessary.


Measuring Teachers' Research Engagement: Finding from a pilot study

Authors: Julie Nelson, Palak Mehta, Jonathan Sharples, Calum Davey
Report and Executive Summary, March 2017

Despite recent policies to support evidence-informed teaching, and a number of important practical developments we still don’t know a great deal about the current extent or depth of evidence-informed practice across schools in England. This paper presents findings from a survey co-developed by the National Foundation for Educational Research (NFER) and the Education Endowment Foundation (EEF), which captured information about this issue in late 2014.

The survey was developed to provide a measure of research engagement across a series of projects, funded by the EEF, which aim to increase schools’ awareness, and use, of research evidence. The survey has also informed the EEF’s overall approach to scaling-up and mobilising evidence – a key priority for the organisation in the second five years of its life.

It suggests that at this point, academic research was having only a small to moderate influence on decision making relative to other sources, despite teachers generally reporting a positive disposition towards research. Additionally, it suggests this positive disposition towards research, and perceptions of research engagement, were not necessarily transferring into an increased conceptual understanding of research knowledge.
