What the test measures
Five areas, one clear picture
Autism is a pattern, not a single behaviour. Our autism quiz asks about the five trait areas clinicians assess — and shows you how your answers cluster.
Routines & flexibility
Rituals, sameness, and how unexpected change lands — from the wrong-colour cup at two to a cancelled plan at forty.
Sensory processing
Sounds, lights, textures, foods and busy places — input most people filter out that can overwhelm or fascinate.
Focused interests
Depth, intensity and absorption in specific topics — the signal is not the interest but its magnitude.
Masking & social energy
The hidden cost of coping: rehearsed behaviour, after-school or after-work crashes, and the recovery time socialising demands.

What is an autism test, exactly?
An autism test — more precisely, an autism screening — is a structured questionnaire that measures how strongly a person shows the traits associated with autism spectrum condition: differences in social communication, a need for routine and predictability, distinctive sensory processing, deep focused interests, and repetitive movement or self-regulation. Screening tools do not diagnose. What they do, and do well, is turn a parent’s scattered observations or an adult’s lifelong questions into a single structured result that says: this pattern is worth taking to a professional — or this pattern currently looks typical.
Our free online autism test covers the same trait territory as the established instruments used in research and clinics — the M-CHAT-R territory for toddlers, CAST and AQ-Child territory for children, and AQ territory for teens and adults — rewritten in plain language and matched to five age bands from infancy to adulthood. You answer one question at a time about everyday, observable life; scoring is instant; and your results page explains your trait band honestly, including what a screening can and cannot tell you.
Free means free — including results
Many autism quiz websites charge at the final screen to reveal the score you already earned. We think that is the wrong moment to put a hand out. Your results here are free in full — the score, the band, the explanation and the next steps — and they always will be. Nomi exists to support families navigating autism; the support starts with not charging you to see your own answers.
After the test: what actually helps
If your result indicates notable autistic traits, the formal route is a conversation with your GP or paediatrician about an assessment referral — and the practical route, which you can start the same day, is understanding and supporting the traits you are seeing. That means tracking patterns (meltdowns, triggers, sensory reactions, what helps), building predictability into the day, and learning from people who have walked this road. The free Nomi app was built for precisely this stage: trackers that turn observations into evidence for assessments, visual routines that lower daily anxiety, an AI companion trained on real therapist conversations, and a community of parents who get it.
FAQ
Autism test questions, answered
Is this autism test really free?
Yes — completely free, including your results. There is no payment step, no card required, no subscription and no fee to see your full score and what it means. You can optionally leave an email to receive your results, but it is never required.
How accurate is an online autism test?
An online autism test is a screening, not a diagnosis. Our questions cover the same trait areas as established research instruments — social communication, routines and flexibility, sensory processing, and focused interests — so a result tells you whether the pattern you are seeing makes a professional assessment worth pursuing. Only a qualified clinician can diagnose autism.
Which autism test should I take?
Choose by age: the baby checklist (under 18 months), toddler test (18 months to 3 years), child test (4–12), teen test (13–17) or adult test (18+). We also have guides for presentations that are often missed — autism tests for girls and for women account for masking and internalised traits.
How long does the autism test take?
Between 3 and 7 minutes depending on the age band — 10 questions for babies, 16 for toddlers, and 20 for children, teens and adults. You answer one question at a time and results are scored instantly.
Can I take the test for my child?
Yes — most people do. The child versions are written for a parent or caregiver answering about everyday behaviour they observe at home. Teens and adults can answer about themselves, and the questions switch to first person automatically.
What do my results mean?
Your score places you in one of four bands, from few autistic traits indicated through to strong autistic traits indicated, with a plain-English explanation and specific next steps for each. A higher score means the traits you reported cluster in the pattern associated with autism — which is exactly the evidence worth bringing to a GP or paediatrician.
Is my data private?
Your answers are stored securely and used only to generate your results and improve the screening. We never sell data, and leaving an email is entirely optional. See our privacy policy for full details.
What should I do after a high score?
Speak to your GP, paediatrician or health visitor about a referral for a formal autism assessment, and bring your results plus concrete examples of what you observe. Waiting lists are long in most areas, so starting the conversation early matters. While you wait, tracking patterns and building supportive routines — what the free Nomi app is designed for — is the most useful thing you can do.

This screening is an informal guide, not a clinical diagnosis. Results are best reviewed with a GP, paediatrician or qualified clinician. Being autistic is a natural form of human neurodiversity.
