There have been many research projects studying the use of peer intervention strategies to develop the social, communication and interaction skills of children with autism, yet few of these studies focus in detail on the impact of such strategies on the mainstream peers. In this article, Val Jones, an advisory teacher for autism spectrum conditions, explores the impact of peer tutoring children with autism on the peer tutors themselves. This enquiry focuses on ten to eleven-year-old mainstream pupils who were paired with twelve children with autism and associated learning difficulties for weekly peer tutoring sessions at a primary school with a specialist autism unit. At the end of a series of tutoring sessions, the perspectives of the peer tutors were gathered through questionnaires. All of the peer tutors reported that they had enjoyed the experience and most felt that the peer tutoring had brought them direct benefits by building confidence, teaching responsibility, encouraging caring attitudes and helping them to acknowledge diversity. Val Jones also gathered the views of parents and school staff who again reported largely positive outcomes from the peer tutoring process. While this small-scale study focuses on findings from one school, there are wider implications here for the development of inclusive policies and practices and this article will be of interest to professionals working across the range of specialist and mainstream settings.
