The strategies put forward by TEACCH do not work on the behavior directly, but on its underlying reasons, such as lack of understanding of what the person is expected to do or what will happen to them next, and sensory under- or overstimulation.

There were positive effects in social and maladaptive behavior, but these results required further replication due to the methodological limitations of the pool of studies analyzed.

[14] The TEACCH approach was developed at the University of North Carolina at Chapel Hill, originating in a child research project begun in 1964 by Eric Schopler and Robert Reichler.

[15] Later, the results of this pilot study indicated that the children involved made good progress,[16] and consequently state finance supported the formation of Division TEACCH.

[2] Founded in 1971 by Eric Schopler, TEACCH provides training and services geared to helping autistic children and their families cope with the condition.
