The aim of this study was to identify support strategies used to promote "social inclusion" and "academic progress" of Key Stage 3 and 4 Gypsy, Roma and Traveller (GRT) pupils. The study used an interpretivist approach, incorporating an embedded single case study with several participant groups, namely GRT pupils, GRT parents, school staff and supporting professionals. The data were collected using interviews, focus groups and questionnaires and were analysed using explanation building--a pattern matching technique which uses theoretical propositions (generated from existing research) to guide analysis and organise data. The study identified one consistent strategy (focussed staff support) to promote both the social inclusion and the academic progress of GRT pupils, and several additional strategies to address each of these areas. The focussed staff support consisted of a dedicated staff member employed to support GRT pupils and families, and act as a consultant for other members of school staff.
