This article explores some of the literature concerning the effectiveness of the Montessori educational approach for children with ASC within an English school context. Firstly, there is a discussion, including a short historical review, regarding the ideology of inclusion and how it has impacted upon mainstream education. Also, how this can be facilitated using play-based approaches such as Montessori. Secondly, various models of disability are identified in order to highlight how they have informed societal attitudes towards people with disabilities. There is a brief history of ASC detailing how a child with this disability may be affected on a daily basis and the effectiveness of alternative play-based educational approaches such as Montessori in helping children with ASC to develop the appropriate skills they need in order to self-regulate and thus modify their behaviour. Furthermore, the value of play-based curriculums in supporting a child diagnosed with ASC throughout the learning process is also evaluated. The summary highlights the need for more evidence-based studies to be undertaken in order to assess whether the Montessori approach is a valid alternative in teaching pre-school children with ASC.
