Research protocol: Evaluating the impact of Eedi formative assessment online platform (formerly Diagnostic Questions or DQ) on attainment in mathematics at GCSE and teacher workload


Stephen Morris, Kathy Seymour, Hayley Limmer


This paper describes a cluster randomised controlled trial designed to test the efficacy of Eedi, a formative question setting and diagnostic digital platform, on attainment in mathematics at GCSE as well as its impact on teacher workload. The study is a pragmatic two arm trial that aims to randomise 180 English secondary schools to intervention and control (business as usual) conditions. The intervention is targeted at Year 10 pupils (aged 14–15 years) and their teachers commencing study of GCSE mathematics from September 2018 and will run for two years. The study is due to report at the end of 2021.
