The Achievement for All (AfA) pilot involved ten local authorities (LAs). Each LA selected schools to participate and in total there were 454 schools. The main aim of the national evaluation project was to examine the impact of AfA on a variety of outcomes for children and young people with special educational needs and disabilities (SEND). It also aimed to find out what processes and practices in schools were most effective in improving these outcomes. Research design incorporated quantitative and qualitative components. The quantitative component of the evaluation consisted of teacher surveys, parent surveys, attendance and attainment data and school level surveys/data. The qualitative component included interviews with local and regional AfA lead professionals, longitudinal case studies of 20 AfA school, and ad hoc data.
