Inclusive education has become a prominent international ideal and value in educational policies and practices. It is a seemingly simple concept about opportunities, equality, and solidarity that has wide global appeal. However, inclusion as applied to education connects with various social and political values that have been contested over many decades. One issue that underlies inclusion as a value is whether it represents a single coherent value or multiple values that can come into tension leading to dilemmas that need to be resolved. This issue is often overlooked in considerations about inclusive education but does affect various key issues about differentiation in the design of curricula and assessment, the location of provision, and how difference is identified and labeled and about participation in the social interaction between students who are different. This is an issue that needs to be addressed.
