An autism evaluation is possible at almost any age — from toddlers showing early developmental differences to adults who have long suspected they see the world differently. A diagnosis isn't a limitation; for many people it's the beginning of a much clearer, more self-compassionate chapter. Here are the core benefits:
New Self-Understanding
Learning whether you or your child has an ASD diagnosis brings new insight into emotional, social, and behavioral reactions — and builds genuine self-acceptance along the way.
Help Others Understand You
A formal evaluation gives schools, employers, and family members a framework for working with your strengths and supporting areas of challenge — rather than misreading them.
Stronger Coping Strategies
Autism testing helps you design coping and stress-management approaches that actually fit how your mind works, and build realistic goals you can reach.
Career and Workplace Insight
An ASD evaluation can guide how you navigate your current job — or help you design a career path that plays to your strengths. We can also document the need for workplace accommodations when applicable.
Who We Evaluate: Children, Teens, and Adults
We offer psychological testing for autism across the lifespan:
- Young children and preschoolers — including preschool evaluations when early signs are present
- School-age children and adolescents — including autism testing for teens
- Adults — including those with lifelong undiagnosed symptoms and those seeking adult autism testing for the first time
- Twice-exceptional individuals — who show both high intellectual ability and autism traits; see our twice-exceptional testing and 2e autism testing pages
Most people who contact us wondering about autism tend to present with milder, high-functioning symptoms — because more significant presentations typically lead to diagnosis earlier in life. We specialize in those subtler profiles that are easy to miss.
How Psychological Testing for Autism Works
Our autism evaluation process is comprehensive, individualized, and structured around your specific questions and goals. Here is how it typically unfolds:
- Clinical Interview: We begin with a thorough interview covering your developmental history, social interactions, communication patterns, and any behavioral concerns. If desired, parents, partners, or other close supports can participate to add context we can't directly observe.
- Social and Behavioral Screening: Standardized questionnaires and rating scales assess how you respond across a range of life situations — and how those patterns compare to those seen with and without ASD.
- Core Autism Assessment Instruments: Depending on what emerges from the screening phase, we move to specialized measures that evaluate communication, social cognition, sensory processing, and repetitive or restricted behaviors.
- Cognitive and Executive Functioning (when indicated): In many evaluations, we include cognitive testing and executive functioning assessment to identify co-occurring learning differences, attention challenges, or intellectual strengths — especially relevant for twice-exceptional profiles.
- Targeted Add-Ons: We tailor the battery around your priorities — whether that's work performance, academic accommodations, relationships, or a general understanding of yourself.
- Feedback Session: We meet with you (and anyone else you'd like to include) to walk through every finding, explain the diagnosis and what it specifically means for you, and present a full set of recommendations. Nothing is left unresolved before we close the session.
- Written Report: You receive a comprehensive psychological testing report with assessment results, diagnostic impressions, and actionable recommendations — typically delivered within 2–3 weeks of testing, with a brief follow-up meeting to review it.
Assessment Instruments We Use
No single test is sufficient for an autism diagnosis. We use a battery of tools selected to match your age, history, and referral concerns. Below are the instruments most commonly included:
We also assess sensory processing, emotional regulation, and anxiety as part of a thorough evaluation, since these frequently co-occur with ASD and shape the overall clinical picture.
Adult Autism Testing: Case Example
Presenting Situation
Emily is a 28-year-old graphic designer who sought an evaluation after recognizing autism traits in herself. She described difficulty with social interaction, a strong need for routine, sensory sensitivities (sound, texture, and light), and consistent challenges reading nonverbal cues. She reported that social settings left her exhausted, and that unstructured or unpredictable environments triggered significant anxiety and burnout. At work, she was highly effective when focused on a project but struggled with open-ended communication and collaborative dynamics.
Emily's goals for testing: understand herself better, help others understand her, manage challenges more proactively, and identify how to leverage her strengths.
Assessment Process
- Clinical Interview: Emily and her parents described a childhood marked by preferring solitary activities, becoming overwhelmed in loud environments, resisting change, and showing intense focus on art and animals.
- Screening Questionnaires: The AQ scored above the clinical threshold. The Sensory Processing screening identified sensitivities to sound, texture, and light. The Beck Anxiety Inventory indicated moderate anxiety, likely secondary to social and sensory demands.
- Observational Tasks: During a structured social interaction task, Emily showed limited eye contact, difficulty reciprocating conversation, and literal interpretation of figurative language. Problem-solving tasks highlighted strong pattern recognition and detail-focused thinking alongside challenges with cognitive flexibility in ambiguous situations.
- Standardized Battery: The ADOS-2 showed clear indicators in communication, social engagement, and restricted/repetitive behaviors. The SRS-2 confirmed meaningful social symptoms. Cognitive testing revealed high-average to superior intellectual functioning with an uneven skill profile.
Diagnosis and Recommendations
Emily was diagnosed with Autism Spectrum Disorder under DSM-5 criteria. Recommendations included:
- Workplace accommodations: noise-canceling headphones, written instructions, and deadline flexibility
- Therapy: Cognitive-behavioral therapy (CBT) to address anxiety and build practical social strategies
- Sensory strategies: identifying triggers and making sensory-friendly environmental adjustments
- Strengths-based approaches: leveraging her superior pattern recognition, attention to detail, and hyper-focus capacity
Autism Testing for Children: Case Example
Presenting Situation
Emily (age 3) was referred after her parents noticed she was not speaking as much as other children her age and showed limited interest in peer play. An initial M-CHAT completed with our guidance indicated a high likelihood of ASD and warranted comprehensive evaluation.
Assessment Process
- ADOS-2: Emily engaged in play tasks during which she showed repetitive behaviors, limited eye contact, and reduced social bids.
- Parent Interview (ADI-R): Developmental history noted delays in speech onset and difficulty with social interaction and transitions.
- WPPSI and Cognitive Testing: Revealed relative strengths in nonverbal problem-solving alongside significant challenges in verbal communication.
Diagnosis and Recommendations
Emily was diagnosed with Autism Spectrum Disorder. The report included recommendations for early intervention services, strategies parents could implement at home to build communication and social comfort, and guidance for managing stress and sensory sensitivities. We also outlined next steps for connecting her with speech-language and occupational therapy services.
Testing for High-Functioning Autism (Asperger's Syndrome)
High-functioning autism — historically called Asperger's Syndrome and now classified within the broader ASD spectrum — is among the most commonly missed diagnoses we see. Strong verbal skills and apparent social functioning often mask significant underlying challenges. We welcome you to contact us or schedule a consultation to discuss whether an evaluation makes sense for you.
What Is High-Functioning Autism?
Asperger's syndrome is a developmental disorder that falls under the autism spectrum. First described by Hans Asperger in the 1940s, it is characterized by strong verbal abilities alongside consistent challenges in social interaction, reading nonverbal cues, and adapting to unpredictability. People with high-functioning autism often develop considerable expertise in focused areas of interest — a strength that coexists with real social and sensory difficulties.
Key features commonly seen in high-functioning autism evaluations:
- Intense focus on specific interests, sometimes at an expert level
- Difficulty understanding social norms, subtle humor, sarcasm, or nonverbal signals
- Sensory sensitivities to sounds, lights, textures, or other stimuli
- Strong preference for routine and predictability
- Anxiety or burnout from sustained social effort
- Challenges with executive functioning and cognitive flexibility
Testing for High-Functioning Autism in Adults
Adults with high-functioning autism often develop coping mechanisms that effectively mask their symptoms — which is precisely why so many reach adulthood without a diagnosis. The effort to appear neurotypical frequently leads to exhaustion, anxiety and depression, and a persistent sense of being out of step with everyone else. Testing can relieve that burden.
A test for high-functioning autism in adults is especially valuable if you:
- Have always found social relationships unusually difficult to form or maintain
- Excel at detail-oriented or technical work but struggle with collaboration or open-ended tasks
- Experience significant sensory discomfort in everyday environments
- Notice that you tend to take things literally or miss implied meanings
- Have been told you "seem different" without anyone ever identifying why
For adults considering self-assessment before contacting us: the Autism Spectrum Quotient (AQ) and RAADS-R are widely used screening tools available online. They are not diagnostic, but they can be a helpful starting point. A full professional evaluation goes much further — identifying your specific strengths, potential, and the practical pathways to manage challenges (including exam accommodations and workplace accommodations when indicated).
Testing for High-Functioning Autism in Children
Early identification of high-functioning autism in children can be transformative. Children who receive timely support develop stronger social and communication skills, experience better educational outcomes, and transition more smoothly into adolescence and adulthood. A test for high-functioning autism in teens and school-age children can unlock targeted accommodations and interventions that make real differences in daily life.
Early signs in children that may warrant evaluation:
- Limited eye contact or delayed speech development
- Difficulty playing cooperatively or understanding social rules of play
- Unusual attachment to specific routines or objects
- Intense interest in narrow topics combined with social disconnection
- Sensory reactions that seem disproportionate to others around them
For our youngest clients, we offer preschool evaluations. Symptoms and how they present differ meaningfully between children and adults — children often show more pronounced social difficulties before they've developed masking strategies, while adults may have compensated in ways that make the diagnosis less obvious but not less real.
Neuropsychological Testing for Autism in Adults
For some clients, a full neuropsychological evaluation is the right next step beyond a standard autism assessment. This more intensive approach provides a comprehensive cognitive, emotional, and behavioral profile of how your brain works across multiple domains. It is not always necessary, but it offers significant advantages when the picture is complex.
What Neuropsychological Testing Adds
- Cognitive profile: A detailed assessment of attention, memory, language, processing speed, and executive functioning — identifying both strengths to leverage and areas that need support strategies.
- Adaptive functioning: Evaluation of real-world skills across communication, socialization, and daily living, using measures of adaptive functioning to guide practical recommendations.
- Social and emotional functioning: Formal assessment of social cognition, emotion recognition, and empathy — providing insight that guides therapy and relationship strategies.
- Sensory processing: Identification of sensory processing patterns — hypersensitivity, hyposensitivity, or sensory-seeking behaviors — so we can recommend environmental and occupational strategies.
- Detection of co-occurring conditions: Many adults with ASD also have ADHD, anxiety, depression, or other conditions that shape treatment needs. Neuropsychological testing distinguishes between them for accurate diagnosis and planning.
After the Autism Evaluation: Feedback, Report, and Next Steps
Feedback Session
Following testing, we schedule a dedicated feedback session — open to you, and to any family members, partners, or supports you'd like to include. In that meeting we:
- Explain each test we administered, why we chose it, and what it revealed
- Walk through your specific strengths and areas of challenge
- Present the diagnostic conclusion and exactly what it means for your life
- Give ample time for questions — we do not move on until you're satisfied you understand
Your Psychological Testing Report
Every client receives a comprehensive written report with test results, diagnostic impressions, and specific recommendations. The report is typically delivered within 2–3 weeks of the final testing session, followed by a short meeting to review it and address any questions.
Recommendations We Provide
Our recommendations are individualized and practical. Depending on your situation, they may include:
- Therapy referrals — such as CBT for anxiety, social skills training, or individual therapy
- Academic accommodations for school or standardized testing
- Workplace accommodations and a supporting letter for your employer or HR
- Sensory strategies and environmental modifications
- Self-advocacy tools and resources for educating those close to you
- Community resources, including organizations like Autism Speaks and local support groups
Ongoing Communication
Our support doesn't end with the report. We maintain open communication as your needs evolve, and can provide follow-up testing when interventions or accommodations need to be documented or updated.
Online Self-Screening Tools for Autism
You can explore autism screening tools even before contacting us. These are not diagnostic — only a licensed psychologist can make a formal diagnosis — but they can give you a sense of whether a full evaluation is worth pursuing:
- Autism Spectrum Quotient (AQ): A 50-question self-assessment covering social skills, attention to detail, communication, and routine preference. Developed by researchers at Cambridge and widely used as an initial screening tool.
- RAADS-R: An 80-question questionnaire developed specifically for adults, covering social relatedness, language, sensory-motor patterns, and restricted interests. Many adults find this measure validating — recognizing that challenges they've carried alone are widely shared.
- Adolescent/Adult Sensory Profile: Focuses specifically on sensory processing patterns — hyper- and hyposensitivity to sound, light, texture, and other inputs — which are common features of ASD.
We can provide links to these tools even if you choose not to pursue formal testing with us. We want you to have information. That said, a comprehensive evaluation goes far deeper — mapping your unique cognitive profile, identifying specific strengths, and producing documentation that opens doors to accommodations and support.

Schedule a Free Consultation Contact UsFrequently Asked Questions About Psychological Testing for Autism
How long does psychological testing for autism take?
Testing typically involves two sessions of 60–90 minutes each, with the first session usually longer because it includes the intake interview. A 45-minute feedback session follows to review your report. The full process — from first session to final written report — is generally completed within one month, with a draft report delivered 2–3 weeks after testing.
Do the results go beyond the diagnosis itself?
Yes — that's the point. While the evaluation will tell you whether you meet criteria for an ASD diagnosis, our primary goal is to give you a clear picture of your unique strengths, challenges, and opportunities. Our reports are strengths-based and solution-focused, not just diagnostic checklists.
Can autism testing be combined with other evaluations?
Absolutely. We frequently combine ASD evaluations with ADHD testing, IQ and cognitive testing, and personality evaluation. Co-occurring conditions are common, and a combined evaluation gives a more complete picture and more targeted recommendations.
How much does autism testing cost?
Costs vary based on the scope of the evaluation. For children, a comprehensive diagnostic evaluation typically ranges from $1,000 to $3,000. Adult autism testing generally ranges from $1,000 to $2,500. Some insurance plans cover part or all of the cost. All evaluations include a written report, feedback session, and — if applicable — documentation letters for school or workplace accommodations.
How accurate is autism testing?
When conducted by a qualified clinical psychologist using gold-standard tools like the ADOS-2 and ADI-R, autism assessment is highly reliable. Online screeners are not diagnostic — they identify traits but cannot substitute for a clinical evaluation. Our evaluations are designed to be both valid (measuring what they're intended to measure) and reliable (producing consistent results if repeated).
What is the most accurate autism test for adults?
The most reliable adult autism diagnosis comes from combining the ADOS-2 (Module 4, designed for adults), the ADI-R interview, and a thorough clinical interview. Used together by an experienced clinician, these tools provide a robust diagnostic foundation. They are the core instruments we rely on for adult evaluations.
Can autism testing be done virtually?
Yes. Most components of our autism evaluations can be conducted remotely. We offer virtual psychological testing to clients across the country. Please contact us to confirm whether your specific assessment needs are suitable for a fully virtual format.
What is the difference between a general autism evaluation and neuropsychological testing for autism?
A standard autism evaluation focuses on confirming or ruling out an ASD diagnosis and documenting your specific profile of strengths and challenges. Neuropsychological testing is a more intensive step that adds detailed assessment of cognitive domains — memory, attention, processing speed, executive functioning — as well as adaptive functioning and sensory processing. It is not always necessary but is particularly valuable when the diagnostic picture is complex or when detailed cognitive documentation is needed for accommodations or treatment planning.
What signs might prompt a high-functioning autism evaluation in adults?
Common reasons adults seek high-functioning autism testing include: longstanding difficulty forming and maintaining relationships, sensory sensitivities that affect daily life, exhaustion from social effort, a history of being called "different" without explanation, literal thinking and difficulty with implied meaning, intense interests in narrow domains, and challenges adapting to change or unpredictability. Many adults who receive a diagnosis in adulthood describe it as a relief — finally having a framework that makes sense of their experience.
What testing and support options are available after a diagnosis?
After a high-functioning autism evaluation, we provide a detailed written report and individualized recommendations that may include CBT for anxiety, social skills training, speech therapy, occupational therapy, educational accommodations, and workplace accommodations. We also connect clients with community resources and organizations like Autism Speaks. Our goal is to make the path forward as clear and concrete as possible.
Ready to Get Started?
Autism is a spectrum, and individuals with ASD bring a remarkable range of strengths. Our evaluations are designed to identify those strengths alongside any challenges — and to give you a practical, solution-focused path forward. We also offer autism spectrum testing for adolescents, testing for high-functioning autism, and broader neurodivergence testing.
