You've watched, wondered, and searched more than anyone around you realizes. Our Naperville center — about a 25-minute drive from St Charles, to the southeast — tests children 4 and under with a play-based evaluation, usually within two weeks, and most insurance covers it.
Our Naperville center — about a 25-minute drive from St Charles, to the southeast — is where our Neuropsychology team provides autism testing. It's one of the closest places a St Charles family can get a real answer, fast.

Testing happens here — not a referral out.
The assessment takes place at our Naperville center, 1755 Park St — on Park Street, just off I-88.
Neuropsychology on site.
Diagnostic questions are handled by our own doctors. No outside waitlist, no re-telling your story.
Appointments in two weeks or less.
Immediate availability for children 4 and under, while most providers quote 6-12 months.
Answers that lead somewhere.
If therapy is the next step, ABA, speech, and OT are all under the same roof.






To your child, it looks like play. To us, it's the gold standard ADOS-2 evalution.
Your child stacks blocks, looks at pictures, and does puzzles while our Neuropsychology team observes the social, communication, and emotional cues that matter. One parent stays in the room the whole time. Intake, testing, and feedback are usually completed in a single visit.
The ADOS-2 engages your child in natural activities — no flashcards, no pressure — to assess the behaviors central to an accurate diagnosis.
Alongside the ADOS-2, we gather an in-depth intake and input from parents and teachers, so the answer reflects your whole child.
One parent is present throughout and may be asked to join in, because your child is most themselves with you nearby.
There's no single sign, but these are the things parents most often tell us they noticed first. If a few feel familiar, an assessment can bring clarity (and often, relief).
Not talking yet, losing words they had, not responding to their name, or not pointing to share things they find interesting.
Limited eye contact, not so interested in other kids, or playing with toys in a repetitive or unusual way.
Strong reactions to sounds, textures, or change; needing routines to feel just-so; or repeating movements to self-regulate.
Every month of waiting is a month of lying awake wondering — and a month earlier support could have started. So we built for speed, without cutting corners.
Our closest testing location for St Charles families is the Naperville center at 1755 Park St — about a 25-minute drive away, to the southeast. It's on Park Street, just off I-88, and our Neuropsychology team provides the full autism evaluation there, so you can get answers close to home.
For children 4 and under, we can usually schedule intake, testing, and feedback within about two weeks — compared with the 6–12 month waits common elsewhere. Spots fill quickly, so we encourage families to reach out as soon as possible.
A diagnosis isn't the end of the story — it's the beginning of a plan. If therapy is the right next step, ABA, speech, and occupational therapy are available at our Naperville center and other nearby locations, so your family doesn't have to start over with someone new.
Our Early Autism Testing Clinic prioritizes children 4 years and under, where early answers make the biggest difference. For older children and other neuropsychological evaluations, we also offer comprehensive testing (currently booking further out).
In most cases, yes — autism testing is covered by most major insurance providers. We'll run a benefits check with you before your visit so you have a clear picture of coverage, co-pays, and deductibles.
The ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition) is the "gold standard" tool for identifying or ruling out autism. It's a play-based assessment that observes how your child interacts, communicates, and engages — combined with a parent intake for the full picture.
We understand the importance of early autism diagnosis and specialized neuropsychological testing. As one of the leading providers of autism testing in the Chicagoland area, we are experiencing a high demand for assessments. However, we make it a priority to accommodate young children as quickly as possible for autism evaluations.
If your child is 4 years old or younger and has been referred for autism testing, we offer:
For all other neuropsychological testing and assessments outside of autism evaluations, we are currently booking appointments 5-6 months in advance due to high demand.
We are committed to providing thorough, compassionate care to help identify and support children with autism spectrum disorder (ASD) as early as possible.

Our Neuropsychology team specializes in autism diagnosis and utilizes the ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition), recognized as the "gold standard" for identifying or ruling out autism spectrum disorder (ASD. This autism assessment is primarily play-based, designed to observe how a child interacts with their environment, probing for key social, communication, and emotional behaviors.
Key elements of the ADOS-2 assessment include:
During the assessment, one parent is always present and may be asked to participate at certain times to help provide a complete picture of the child's behavior and interactions.
Our team is dedicated to providing thorough and compassionate autism evaluations, ensuring you receive the most accurate and timely diagnosis for your child.
Our early intervention services are offered independently, with no affiliation with the Illinois Early Intervention Program. However, our therapists have deep experience working with children of all ages, especially those 3 years old and younger. Our private practice provides a range of therapies, including speech, occupational, physical, mental health, Applied Behavior Analysis (ABA), and autism or comprehensive neuropsychological testing, tailored to meet the unique needs of each child.
While both programs aim to support children's development, there are a few important differences. You should make the most appropriate and reasonable decision for your family and child’s current situation.

The team is amazing. Our son has made so much progress. The work of his therapist and lead ABA coordinator have helped him to move through many of his goals faster than expected. We are so appreciative of the staff at North Shore.
Excellent RBT pairing, amazing plans and goals beautifully implemented in my son's treatment plan! He's thriving! Thank you!
My child attends both OT and speech therapy and we’ve had a very positive experience with the therapists and NSPT as a whole. Very pleased with how everything is going and I’m confident we are getting him the right and professional assistance that he needs.
NSPT is full of passionate and professional staff members that truly care. Thank you for all you do!
Tell us a little about your child, and we'll take it from there — a benefits check, a date on the calendar, and answers within weeks.
