The document discusses the concepts of mainstream education, special education, integrated education, and inclusive education. It defines each concept and compares the differences between integrated education and inclusive education. Integrated education aims to educate some special needs children alongside regular students with some support, while inclusive education aims to educate all children who have been excluded from education by providing special infrastructure, curriculum, and trained staff to meet their diverse needs. The key difference is that inclusive education has a broader scope of including all excluded students, while integrated education may have its own criteria for which students to include.
