Inclusion is based on the principle that every individual is able to fully participate in and contribute to his/her community, which is the foundation for an inclusive society. An inclusive society is one that facilitates the inclusion of all, including the most marginalized groups. In today's society, effective inclusion is also based on the education of the individual. Inclusion is not merely about putting all children into one school regardless of whether any learning takes place. It is also about including all marginalized groups in the learning process (including those marginalized based socioeconomic status, cultural background, disabilities, and gender). Children with disabilities are especially vulnerable as they often face a double handicap: one due to the disability and the other due to, for example, their gender, socioeconomic status, and/or cultural background. This double handicap makes the problem more complex. Deep-rooted societal prejudices may prevent children with multiple disadvantages from fully participating in society and this starts with learning and progressing to decision making.

Inclusive education is an approach to educate all children who are at risk for neglect in education system. It expects that all learners learn together through access to common educational provisions. The crucial people in the system are the parents, and community, teachers, administrators and policy makers. All these people have to be supportive towards the diverse needs of children. It should be seen as an experience rather than a problem.
