Segregation

Segregation is the act by which a person separates other persons on the basis of race, color, language, religion, nationality or national or ethnic origin without an objective and reasonable justification. 

Within the education system, segregation refers to the operation of a school system in which learners  are wholly or substantially separated among the schools on the basis of ability, race, color, sex, or national origin, or within a school on the basis of ability, race, color, or national origin. Segregation has been a common approach to disability, among others identifiers mentioned, due to a belief that children and adolescents with disabilities cannot learn alongside their peers due to their diverse needs.
