The main concern with segregating children to special education classrooms is that they may not really need to be in the special education class at all. The criticism is more about the criteria that identifies a child as a special needs child. Some children with ADHD, OCD, Anxiety Disorder, and other mental disorders that are controlled with medication would be just fine in a regular classroom setting and the critics feel that their potential is limited by placing them in a special education environment. On the other side of the coin, children who are in need of special education are often denied based on the criteria.
Regardless of the criticism or the method of providing children with special needs the education they deserve, as long as the child is learning and growing at a reasonable pace based on their limitations, and not pushed to the point of failure, then the special education system is working. There will be flaws in any system. We, as parents of special needs children, need to get involved in our children’s education and make sure that they are getting the very best education that the system has to offer them.
