The main goal of both special education and inclusive education for young people with learning or behavioral difficulties is their maximum inclusion in the community as adults. The question of which of these two approaches is more likely to achieve this goal is addressed by considering the findings of three outcome studies of young people with moderate to severe levels of learning or behavioral difficulties who experienced either option, or some combination of the two. The overall findings indicate that students who left school from a special education setting had better outcomes than those who completed their education in mainstream schools. This is considered to be due to the vocational curriculum and work experience they gained in their final years of special education, which those in mainstream schools did not receive. This suggests that a policy of full inclusion, with the closure of special classes and special schools, will result in less inclusion in their communities post-school for young people with moderate to severe levels of learning or behavioral difficulties.
