The purpose of this study was to investigate the perceived high turnover of teachers working with pupils with severe and profound general learning disabilities in Ireland. Questionnaires and interviews were used to explore the situations in which teachers worked and their reasons for leaving or staying in teaching this group of pupils. The study found that while teachers were positive about working with this group, their working conditions and the level of support that they received were crucial factors in determining whether they remained in post. These factors and the implications for practice are discussed.
