In this article, the author reflects on findings from research on the role and impact of teaching assistants and experience of working as a special educational needs (SEN) officer. Research evidence suggests the reliance on teaching assistants to include pupils with Statements of SEN in mainstream settings masks a collective, though unintentional, failure of educationalists to articulate and provide schools and families of children with SEN with appropriate and pedagogically sound models of inclusive provision. In light of the forthcoming reforms to the SEN system in England, key implications for educational psychologists (EPs) are drawn out, with particular reference to their role in parent liaison during the statutory assessment process.
