First off it is a steep claim to make, as you appear to have no actual knowledge of anything but TEACCH. You make many claims regarding ABA but seems to have no actual knowledge. I dislike the TEACCH program because I have seen how much it has damaged my son! Thank God that there are alternatives with proven effektiveness.
When you claim that all ABA studies claiming more than 5 IQ points gain, are fraudulent, why dont you seem to worry about the "honurable" TEACCH founder Eric Schopler's study (Lord & Shopler, 1989) that claims a 22-24 IQ point gain from ages 3-7. There are so many unfounded claims surrounding TEACCH that it is hard to take serious.
