Please tell me how long it takes for to make a proper autism evaluation?

Should not take long: Except in rare cases it should not be that difficult or time consuming to make the diagnosis if you are in contact with the correct providers. No lab or diagnostic testing is necessary although it is usually done at some point. The diagnosis is made utilizing a standard set of criteria that evaluates the presence or absence of specific behaviors combined with some level of speech/language delay.

A team with a Devel-: Opmental/behavioral pediatrician, child neuropsychologist, etc., spend 6-12 hrs. Or > assessing cognitive, social/adaptive, communication, fine & gross motor development by 1) review of prenatal-current medical, developmental & family history 2) standardized checklists & tests of current functioning & degree of autism & 3)medical evaluation for etiology, including neurological & genetic testing.
