Research Autism gives it one tick on their website http://www.researchautism.net/interventionitem.ikml?ra=21 . This means there is only a weak evidence base to support TEACCH. Be warned, the evidence that does exist is based on TEACCH delivered in the optimal way, by skilled practitioners and in the best setting. This is not what you get in the average Local Authority school!!!
Research Autism comments about TEACCH “we have concerns about the objectivity of some of the research conducted to date. And we also have concerns that the outcomes may depend to a large extent on the skills and experience of individual staff involved in TEACCH.”
ABA gets 3 ticks, because there is now a good evidence base to support its use.
