Project TEACCH (Treatment and Education of Autistic and related Communication-handicapped CHildren)
Description : In TEACCH, children and adults with autism spectrum disorders receive individual classroom instruction designed to accommodate learning styles characteristic of autism spectrum disorders. For example, because visual skills tend to be more advanced than verbal skills, instructions may be presented in pictures rather than words, and tasks may have visual prompts (e.g., grooves to indicate where to place items, pictures of each step of the task, etc.). Because classroom noise or intrusions from peers may be distracting or aversive, individuals with autism spectrum disorders often work at their own workstations rather than with classmates, though small group instruction also occurs. Because transitions from one activity to another may be difficult, individuals with autism spectrum disorders may have a highly structured schedule placed at their workstations.
Research Summary: TEACCH is widely considered to be a plausible intervention approach (i.e., one that could be effective; National Research Council, 2001). One small but well-designed study indicated that parent training provided by TEACCH may accelerate the development of cognitive and self-help skills (Ozonoff & Cathcart, 1998). Another small study indicated that TEACCH workstations may increase on-task behavior and completion of assignments (Hume & Odom, 2007). Other aspects of TEACCH such as classroom instruction have support from preliminary studies (e.g., Lord & Schopler, 1989) but have not been evaluated in peer-reviewed studies with strong experimental designs.
Recommendations: An important area for future research is to evaluate TEACCH in studies with strong experimental designs. Professionals should present TEACCH as untested and encourage families who are considering this intervention to evaluate it carefully.
