This paper focuses on a major challenge facing education systems around the world, that of finding ways of including all children in schools. In economically poorer countries this is mainly about the millions of children who are not able to attend formal education (UNESCO, 2015). Meanwhile, in wealthier countries many young people leave school with no worthwhile qualifications, whilst others are placed in special provision away from mainstream education and some choose to drop out since the lessons seem irrelevant (OECD, 2012). Faced with these challenges, there is evidence of an increased interest in the idea of making education more inclusive and equitable. However, the field remains confused as to the actions needed in order to move policy and practice forward.
