Is an autism evaluation the same as autism testing?

Yes. At Mosaic, a licensed psychologist evaluates your child using play-based activities, standardized autism testing tools and your input as a parent, then explains whether your child meets the criteria for an autism diagnosis.

How is autism diagnosed in young children?

Autism is diagnosed through a careful evaluation rather than a single medical test. A licensed psychologist decides whether your child meets the criteria in the DSM-5-TR, the manual clinicians use to diagnose autism. The psychologist looks at two areas. The first is social communication, such as eye contact, gestures, words, responding to their name and sharing play with others. The second is restricted or repetitive behaviors, such as repeated movements or words, a strong need for sameness, very focused interests, or unusual reactions to sounds, textures or other sensations. The psychologist combines what you share about your child’s development with their own observation, which can include the ADOS-2, a play-based assessment of communication, social interaction, play and repetitive behaviors. They also consider how much these affect daily life and whether something else, such as a developmental delay, better explains what they see.

At what age can my child be evaluated for autism?

We provide comprehensive autism evaluations for children from 18 months through 4 years of age (up to their 5th birthday). Our early intervention focus allows us to specialize in the unique developmental patterns and assessment approaches most effective for toddlers and preschoolers.

What if my child is approaching their 5th birthday?

If your child is nearing their 5th birthday and you're considering an evaluation, we encourage you to contact us as soon as possible. We can typically accommodate children who begin the evaluation process before turning 5, even if some appointments extend slightly past their birthday. For children who are already 5 or older, we maintain relationships with excellent providers who specialize in school-age evaluations and can provide appropriate referrals.

What should I expect during my child's autism evaluation?

Our evaluation process is designed to be comfortable and engaging for your child. It starts with a virtual visit with the psychologist, followed by an in-person assessment at a Mosaic clinic. We use a variety of activities including structured play, interactive tasks, and observation in different settings. Your child may participate in activities like puzzles, games, and social interactions while our clinicians observe their communication, behavior, and developmental skills.

When will we get the results of the autism evaluation?

Usually within about a week of the in-person assessment. You’ll meet with the psychologist to go over the results and next steps, and you’ll receive a written report.

Do you accept my insurance for autism evaluations?

We accept all major insurance plans, including Medicaid. Most plans cover autism diagnostic evaluations, and our team checks your coverage before your appointment.

How should I prepare my child for the evaluation?

The best preparation is keeping your child's routine as normal as possible before the appointment. Bring any comfort items your child might need, and let them know they'll be playing games and meeting new people. We offer a variety of appointment times to accommodate your family's needs and your child's schedule.

Does Mosaic's evaluation include the ADOS-2?

The ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition) is a play-based observation that psychologists often use as one part of an autism evaluation. At Mosaic, it may be one of the tools your child's psychologist uses during the in-person assessment. The psychologist chooses the tools that fit your child, so you don't need to ask for the ADOS-2 separately.

Do I need a referral?

No. You can request an evaluation directly on this page. If your insurance plan requires a referral, our team will let you know.

Is there a waitlist?

No. There's no waitlist for evaluations.

What's the difference between a screener and an evaluation?

A screener is a short questionnaire that shows whether a closer look may help. It can't tell you whether your child has autism. An evaluation is done by a licensed psychologist: a virtual visit, then an in-person assessment. Only an evaluation can lead to a diagnosis.
