Face it, not all special education advice is equal. We've all been there, well-meaning but ill informed neighbors think they're helping when they give you newspaper clippings about the latest "miracle cure" for your disabled child. Or an experienced general ed teacher insists the approach that works wiith all the other kids will work for yours.
There's a terrific resource on a blog I've just started following http://www.autismisnottheboss.com/. Although the site is autism specific, this particular tool is useful across disabilities.
