**1. Introduction**

Procedures based on the science of behaviour analysis have been used successfully to address socially important behaviours at home, in communities, clinics, classrooms, and businesses [1, 2]. Common goals include improving social skills and academic attainments or the reduction of disruptive behaviours. Many of these methods have been used successfully to support individuals on the autism spectrum [3]. In this chapter, behaviour analysis is described first, then autism aetiology, diagnosis, and prevalence are briefly explicated. The focus then moves onto specific procedures that are particularly effective in supporting children with autism and, finally, professional certification for behaviour analysts is described.
