This research seeks to compare reports of theory and intervention use that are prevalent in mainstream and special schools within a local authority (LA) and in out of county special schools used by the LA when supporting children with ASD. The objective is to make recommendations for further research and suggest how inclusion of children with ASD may be supported in mainstream schools. This is done in order to find ways for the LA to reduce expensive out of county and specialist school resources by improving the inclusion of children with ASD in LA mainstream schools. The study by Greenway (2000), who reviews strategies to promote pro-social behaviours for children with ASD, is used as a basis from which to review theoretical backgrounds and intervention.
