AQ-10 Autism Test Explained: What the Score Means and What to Do Next
Published November 2, 2026 · Last updated November 2, 2026
If you have come across the AQ-10 online or been given it at a clinic, you may wonder what it measures and what your score means. This guide explains what the AQ-10 is, how it is scored, how reliable it is, and how to use it sensibly, including what to bring to a doctor.
The AQ-10 is a 10-question screening questionnaire for autistic traits, a short form of the 50-question Autism Spectrum Quotient. A score of 6 or more suggests considering a referral for a full assessment. It is not a diagnosis, and many people who score 6 or more are not autistic, so use the result to start a conversation with a clinician.
- What it is: A 10-question screening questionnaire for autistic traits.
- Cut-point: A score of 6 or more suggests considering a full assessment.
- Not a diagnosis: It supports referral decisions. Only a clinician can diagnose.
- Versions: Adult (16+), adolescent (12 to 15) and child (4 to 11).
What Is the AQ-10?
The AQ-10 is a 10-question screening questionnaire for autistic traits. It is a short version of the longer 50-question Autism Spectrum Quotient (AQ), developed by researchers at the Autism Research Centre in Cambridge and published by Allison and colleagues in 2012. They chose two questions from each of the five areas of the longer test, to make a quick "red flag" tool that could help a doctor decide whether to refer someone for a full assessment.
Which Version Is for Whom?
| Version | Who answers | Age |
|---|---|---|
| Adult | The person themselves (self-report) | 16 and over |
| Adolescent | A parent or carer (parent-report) | 12 to 15 |
| Child | A parent or carer (parent-report) | 4 to 11 |
For toddlers and younger children, doctors usually use other tools. The CDC lists a number of screening tools in its guidance for clinicians. Ask your pediatrician which one they use. See our guide to autism symptoms and signs by age.
How Is It Scored?
Each answer that fits an autistic trait scores one point. The recommended cut-point is 6. A score of 6 or more suggests considering a referral for a full assessment.
How Accurate Is It?
In the original study, the AQ-10 did well at picking up people who had already been diagnosed, with high sensitivity and specificity in the groups studied. But the authors noted limits: the study was retrospective, diagnoses were self-reported, and accuracy depends on how common autism is in the group tested. They estimated that in a general population where about 1% have autism, the positive predictive value of the adult version would fall to roughly 0.09. In plain words, many people who score 6 or more will not turn out to be autistic when assessed. The score can start a conversation, not end one.
How to Use an AQ-10 Sensibly
- Answer honestly and think of typical days, not your best or worst day. For a child, use how they usually are.
- Write down examples that support each answer. Real moments are more useful than a score.
- Ask someone who knows you or your child well to read your answers. They may notice things you do not.
- Do not stop at the score. Share it with a doctor with your examples.
Why Some People Score Low and Are Still Autistic
Many people mask, meaning they hide or compensate for autistic traits. Girls and women in particular may score lower than their daily experience suggests. See autism in girls and women. A low score should not stop you from asking for an assessment if daily life is hard.
What to Do After a Screening Result
How to Prepare for the Doctor, With Real Examples
Doctors can do more with specific examples than with a test score. Here are examples of what to bring and why.
| Bring | Example | Why it helps |
|---|---|---|
| Short videos of everyday moments | Play, mealtime, a transition, a meltdown | Clinicians can see behaviors you struggle to describe |
| A list of early milestones | When first words, pointing and waving appeared | Early development matters for diagnosis |
| School or nursery reports | Teacher comments, behavior notes, support plans | Shows how your child functions outside home |
| A list of sensory issues | Sounds, textures, foods, lights | Part of the diagnostic picture |
| A list of strengths and interests | What they love and are good at | Helps shape a support plan |
| Your questions | What support is available? What happens next? | Makes the visit useful |
Other Tools You May Hear About
The AQ-10 is only one of several tools. Some are quick questionnaires that help decide whether to refer, and others are part of a full diagnostic assessment. Knowing which is which helps you understand what your doctor or clinic is doing, and what to ask for.
Screening tools (short, help decide on referral)
| Tool | Who it is for | What it is | What to expect and why it matters |
|---|---|---|---|
| M-CHAT-R/F | Toddlers, about 16 to 30 months | A 20 question yes or no questionnaire filled in by a parent, with a short follow-up interview when needed | Often used at routine pediatric visits. It looks for early signs such as response to name and pointing, so parents can get a referral early, when support helps most |
| AQ-10 (child, adolescent, adult) | Ages 4 to 11, 12 to 15, and 16 and over | 10 short questions on autistic traits, parent-report for children and self-report for adults | Takes a few minutes. Helps a doctor decide whether to refer, and cannot diagnose |
| AQ-50 and RAADS-R | Mostly adults | Longer self-report questionnaires about autistic traits | Useful for adults who suspect they are autistic and want examples to bring to a clinician. Still not a diagnosis |
| SCQ and CAST | School-age children | Parent questionnaires about social communication and behavior | A school-age option when concerns come up later, often because a child has coped well in early years |
Diagnostic tools (used by a trained clinician)
| Tool | What it is | What a parent will notice | Why clinicians use it |
|---|---|---|---|
| ADOS-2 | A structured, play-based or conversation-based observation, with different modules for age and language level | Your child plays, chats or does simple tasks with the clinician, who watches communication, play and social response | It lets the clinician see behavior directly, which a questionnaire cannot |
| ADI-R or a similar developmental interview | A detailed interview with a parent or caregiver about early development and current behavior | Questions about first words, play, routines, sensory reactions and daily skills. Bring notes and videos if you have them | Early history matters, and you know your child best |
| Developmental and language assessments | Tests of language, thinking skills and sometimes motor and sensory function | Short tasks with a psychologist or therapist | Autism often appears alongside language, learning or sensory differences, and support plans need this detail |
A diagnosis is normally based on several of these together, the clinician's own observation and the full developmental history, not on one score. That is why a single questionnaire result should never be treated as the answer.
How to use this information
- Ask which tools your clinic uses. It tells you whether you are at the screening or the diagnostic stage.
- Prepare examples. Videos of play, a list of sensory reactions and notes from school or daycare make any tool more accurate, because the result depends on what the clinician can see and hear about.
- Ask about waiting times. Assessment lists can be long, so ask what support can start in the meantime. Speech, occupational therapy and classroom supports often do not need a diagnosis.
- Keep your own record. Our parent profile tool is not a diagnostic test. It helps you organize your child's sensory and support needs so you can describe them clearly at any appointment.
Frequently Asked Questions
What is the AQ-10 test?
It is a 10-question screening questionnaire for autistic traits, a short version of the 50-question Autism Spectrum Quotient. It helps a doctor decide whether to refer someone for a full autism assessment.
Can the AQ-10 diagnose autism?
No. It is a screening tool, not a diagnostic test. Only a qualified clinician can diagnose autism after a full assessment.
What is a high score on the AQ-10?
A score of 6 or more is the recommended cut-point for considering referral for a full assessment. It does not mean you or your child is autistic.
What if I score below 6 but think I am autistic?
A lower score does not rule out autism, especially if you mask your traits. If daily life is hard, you can still ask your doctor about an assessment.
Is there an AQ-10 for children?
Yes. There are parent-report versions for ages 4 to 11 (child) and 12 to 15 (adolescent), and a self-report adult version for ages 16 and over.
How accurate is the AQ-10?
In the original study it performed well in the groups tested, but the authors noted limits. Where autism is uncommon, many people who score 6 or more will not turn out to be autistic.
Are online autism tests reliable?
Online tests can help you think about your traits, but they are not diagnostic. Use them to start a conversation with a doctor, and bring examples.
What should I do after taking the AQ-10?
Write down examples that support your answers, share the result and examples with your doctor, ask about a full assessment, and start any supports that help in the meantime.
