This article examines the pattern of placement of students with significant special educational needs at Statement and School Action Plus levels in English secondary schools, comparing sponsored and converter academies, maintained schools and the newly created free schools, studio schools and university technical colleges for 2013 and 2014. The analysis shows a clear pattern of differences: converter academies (which are governed by their own governing body) had significantly lower proportions of students with significant special educational needs overall than maintained (those remaining under local authority management) and sponsored academies (those considered to be weak/failing schools forced to become academies with outside sponsors that oversee the schools). There was a similar pattern of findings for most areas of special educational needs, except visual impairment and autistic spectrum disorder. The pattern of placement of students with Statements in the newly created free schools also showed that some free schools have unusually high proportions of students with special educational needs. These findings are discussed in terms of the increasing stratification of English secondary schools and the potential of small secondary schools to be more inclusive.
