There are no known hazards for the TEACCH Autism Program, although it has been criticised by some people. For example, according to the Autism Gateway website accessed on 16 August 2017,
“There have been criticisms that the TEACCH approach is too structured, that children with ASD, particularly those individuals who are less affected, become too focused on the charts, organizational aids, and schedules, and that it discourages mainstream behavior (meaning that they may only respond to specific stimuli as taught in their curriculum and not everyday situations). Others feel that, in an environment conducive to learning, ultimately the child with ASD understands what is expected and how to respond.”
There are no known contraindications (something which makes a particular treatment or procedure potentially inadvisable) for the TEACCH Autism Program.
