This study investigated the impact of different aspects of the circle of friends (CoF) intervention. A naturalistic sample of 14 primary-aged children with a range of special educational needs were involved, seven of whom were followed-up a term later, to assess medium-term impact. The whole-class meeting was found to be effective in increasing the social inclusion of the focus children. However, with the exception of one child with an autistic spectrum disorder (ASD), the weekly CoF meetings produced no measurable further improvements. Possible explanations for the pattern of findings and implications for educational psychology practice are discussed.
