Diagnostic Evaluations
(Getting a Diagnosis)

One of the most important factors in the long-term outcome for individuals with autism is an accurate diagnosis. AZA United’s team of deeply experienced clinical psychologists conducts thorough evaluations for individuals of all ages to determine all relevant diagnoses (not just autism) so that individuals and families can seek appropriate treatments and supports. Our Family Support Team also guides parents through the process both before and after, so that no one ever gets stuck or feels alone on their journey to success. 

What is a Diagnostic Evaluation?

Diagnostic evaluations are conducted by a Licensed Clinical Psychologist with specialized training and expertise in diagnosing autism spectrum disorder (ASD) as well as other developmental disabilities, behavioral disorders and related conditions. Evaluations are available for any age and may be an important step toward gaining access to treatments and services.


An accurate diagnosis can provide families a better understanding of how to help their loved one. It also assists therapy providers in determining the best course of treatment to improve long-term outcomes and qualify of life.
