There are advocates that autistic children should be brought out of the mainstream classes and put into a more restrictive environment that will limit the sensory items that might distract or upset the child. The autistic child needs to have a pattern in their lives and in the mainstream classroom; the hustle and bustle of public education settings may lead them to sensory overload. Not only that but the social aspect of being different and not being able to contribute or communicate to the rest of the class can be heartbreaking to both the student and the teachers involved. The self-contained class room will break down tasks into manageable chunks that the child can be successful and maybe eventually learn.
The treatment process goes on both at home and at school. The autistic child must be taught how to appropriately interact with others. A common behavior in autistic children is to take off their clothes. They see no sense of wrong or right by being nude in public. Such behaviors need time and patience to mend and some methods might work for one child and then be completely a failure for others. Parents, teachers, and medical professionals need to keep abreast of new treatments so that they can replace a treatment or method that has been proven a failure for a particular child. Sometimes the behavior cannot be changed at all and the individualize education program must come up with strategies to deal with the behavior.
Parents and teachers must remember that the autism is a life long condition and as the child moves through life the treatments must change to fit the life period of that child. The changes are not understood by the child, but like Pavlov's dog, a conditioned response may be instilled in the child and the proper behavior may be a learned response.
