Diagnosing ASD  

ADOS-2 Testing

How will I know if my child meets criteria for Autism?

The Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) is a semi-structured, standardized assessment of communication, social interaction, play/imaginative use of materials, and restricted and repetitive behaviors for individuals who have been referred because of possible autism spectrum disorders (ASD). The ADOS-2 is a revision of the Autism Diagnostic Observation Schedule, which has been referred to as the “gold standard” observational assessment for diagnosing ASD. Children as young as 12-months, regardless of verbal ability, can be assessed using the ADOS-2.



Who makes the diagnosis?

The ADOS-2 can administered with other assessment measures by a developmental pediatrician, a pediatric neurologist, or licensed psychologist trained to administer this assessment for the purpose of diagnosis. The assessment results may qualify your child for in-home therapy.



Why is an ASD diagnosis necessary?

By obtaining an accurate diagnosis, individuals and families can begin to access appropriate intervention services, obtain individualized behavioral and educational programs, and determine patterns of strengths and weaknesses at the current developmental level. Determining an accurate diagnosis is a first step for a clinician in defining a treatment plan for a child. In short, children with autism spectrum disorder cannot begin to receive ABA therapy without first being diagnosed. No medical referral is necessary. POSS offers comprehensive evaluation reports at lower out-of-pocket costs with significantly shorter wait-list times than those at major hospitals/medical facilities.
