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. [This report was written with Chris Brown.
