Verbal I.Q. The comprehensive evaluation for Autism is critical since a basic IQ score may be skewed due to verbal comprehension or verbal IQ. It is not uncommon for nonverbal children with AUTISM to have a high IQ. Various measurements during the evaluation involve verbal tasks, understanding written material and answering general knowledge questions. Assistive and Augmentative Communications (AAC) such as flashcards, I-pads, etc. may be used for tests and assessments.
