Between June 2018 and November 2020, the National Foundation for Educational Research (NFER) conducted an evaluation of the Tailored Support Programme (TSP) on behalf of the Department for Education (DfE). The aim of the evaluation was to explore perceptions of the TSP and, in particular, gather data on: reasons for engagement; what was delivered; what worked well and less well and why; perceived impacts; sustainability; challenges in engaging with the programme; and what has been learnt for future recruitment and retention programmes. The main report focuses primarily on the findings from the in-depth qualitative data, drawing on selected survey findings where appropriate. For context and completeness, this document provides more detail on the responses from the baseline surveys. Some analysis of Department for Education (DfE) management information is also included, where relevant. [For "Evaluation of the Tailored Support Programme: Final Research Report," see ED612540.]
