In Scotland, the growth of behaviour support provision is closely related to broader policy on social inclusion. It is argued in this article that new models of behaviour support can be developed in the light of previous and related experience in the development of inclusive support systems in schools. The authors present a typology of behaviour support, drawing upon their evaluation of provision, and discuss the characteristics of the types of support that emerge. Using data from exclusion statistics, pupil case studies and interviews with teachers, managers, pupils and parents, Jean Kane, George Head and Nicola Cogan explore the implications of their work for future developments in support for pupils who present difficult behaviours.
