it varies from location to location. your treatment provider can tell you what psychiatric evaluations/learning disorder evaluations/ IQ testing is available in your location.

here in NY we use a comprehensive approach which means we administer psychiatric tests for all mental disorders, academic/IQ testing, physical health testing that involves seeing both medical doctors and psychiatrists for complete testing due to the fact that many mental, physical and normal problems can impact a person's life on social, academic, behavioral and other levels of functioning.

only your treatment providers or a treatment provider in your own location can tell you what tests you or someone you know will have to take. my suggestion contact a treatment provider in your off line location. tell them you are interested in the availability for diagnostic testing of mental disorders/mental retardation and they will tell you what you must do to get that done.
