I thought of this as I read Labour’s overhaul of Send, the system for special educational needs and disabilities in England. These are significant and complex changes, many of which will not fully come into force until 2030, but “inclusion” is the overriding theme: all mainstream schools will now have tailored support to – in the government’s words – “make every school truly inclusive”, with multibillion-pound funding for 60,000 additional special-needs places and “inclusion bases” in all schools. Children with the most complex needs will still be able to attend specialist schools.
