Stanley Park High School, Carshalton was designated a Building Schools for the Future "One School Pathfinder" in 2006, and charged with being innovative in all aspects of schooling. This article, which links with a number of other contributions in this issue of "FORUM" about interconnected practices at the school, will focus on one of the four schools-within-a-school (SWS), Horizon. This SWS is markedly different from the other three because it contains two opportunity bases--Aqua and Ignis--that in total meet the needs of 91 students with an Education and Health Care Plan for Autism Spectrum Condition (ASC), a provision that we believe to be unique within a mainstream secondary setting in England.
