Inclusion is both a principle and a process: ‘Inclusion and equity in and through education is the cornerstone of a transformative education agenda […] No education target should be considered met unless met by all’ (World Education Forum, 2015, p. 2).

It can be seen as: ‘A process consisting of actions and practices that embrace diversity and build a sense of belonging, rooted in the belief that every person has value and potential and should be respected’ (UNESCO, 2020a, p. 419).

The term was often associated with disability, but now extends to wider groups as ‘a response to increasingly complex and diverse societies. It treats diversity as an asset which helps prepare individuals for life and active citizenship in increasingly complex, demanding, multi-cultural and integrated societies’ (Soriano, Watkins and Ebersold, 2017, p. 7).

‘An education that promotes mutual respect and value for all persons and builds educational environments in which the approach to learning, the institutional culture and the curriculum reflect the value of diversity’ (UNESCO, 2020a, p. 420).

The Agency views inclusive education as ‘a systemic approach to providing high quality education in mainstream schools that effectively meets the academic and social learning needs of all the learners from the school’s local community’ (European Agency, 2015, p. 2).

Inclusive education supposes a real change at both policy and practice levels regarding education. Learners are placed at the centre of a system that needs to be able to recognise, accept and respond to learner diversity. Inclusive education aims to respond to the principles of efficiency, equality and equity, where diversity is perceived as an asset. Learners also need to be prepared to engage in society, to access meaningful citizenship and to acknowledge the values of human rights, freedom, tolerance and non-discrimination (Soriano, Watkins and Ebersold, 2017, p. 6).
