AQ Test – Free Online Autism Quotient (AQ-50) Self-Assessment
What is the AQ Test (AQ50)?
The AQ test is one of the most widely used autism screening tools in the world. Developed by researchers at the University of Cambridge, the AQ test — formally known as the AQ-50 or Autism Spectrum Quotient — helps adults understand whether their patterns of thinking, communication, and behaviour align with autistic traits.
The AQ test is not a diagnostic tool, but it’s a well-validated first step for anyone curious about their neurodivergent profile or considering a professional autism assessment. Complete the 50 questions and you’ll receive an instant score with a clear interpretation of what it means.
If you’re looking for a more in-depth assessment, the RAADS-R autism test covers 80 questions across additional domains and is specifically designed for adults who may have been missed in childhood.

How are AQ test scores interpreted?
Your AQ test score reflects how closely your responses align with traits commonly associated with autism.
While only a qualified specialist can diagnose autism, your AQ-50 score can be a useful indicator of whether your patterns of thinking and behaviour are worth exploring further.
Average AQ Test scores:
- Autistic adults often score 32 or above
- Non-autistic adults typically score 15–17
| Score Range | Interpretation |
|---|---|
| 0–19 | Low autistic traits – typically aligned with neurotypical thinking and behaviour. |
| 20–25 | Mild autistic traits – certain preferences or differences may be noticeable, but unlikely to significantly impact daily life. |
| 26–31 | Moderate autistic traits – traits are more prominent and may influence communication, social interaction, and daily routines. |
| 32+ | High autistic traits – scores in this range are common among autistic adults and may indicate that a professional autism assessment could be helpful. |
Why Should You Take the AQ Test?
The AQ test is free, takes just 10–15 minutes, and gives you an instant score — whether you’re exploring autism traits for the first time or looking for a recognised starting point before a professional assessment.
Self-Awareness
Understand how your thinking, communication, and behavioural patterns compare to common autistic traits.
Scientifically Backed
Backed The AQ-50 was developed and validated by Professor Simon Baron-Cohen’s team at the University of Cambridge Autism Research Centre.
Quick and Easy
Complete the full AQ test in 10–15 minutes, with your score available the moment you finish.
Actionable Results
Use your AQ test score to guide next steps — whether that’s connecting with a professional specialist or simply understanding yourself better.
What Does the AQ Test Measure?
The AQ test was created by Professor Simon Baron-Cohen and colleagues at the Autism Research Centre, University of Cambridge.
The AQ-50 was designed to measure the degree of autistic traits in adults of average or above-average intelligence, and has since become one of the most widely used autism screening tools in research and clinical settings worldwide.
The AQ test covers 50 questions across five key areas:
Creative thinking and ability to visualise scenarios
Comfort and ease in social situations
Flexibility in changing tasks and adapting to new situations
Awareness of patterns, accuracy, and precision
Verbal interaction, interpreting tone, and conversational flow
What to Do After Your AQ Test?
If your AQ test score suggests elevated autistic traits, there are a few practical next steps worth considering.
- Unlock Your Personalised Report: Once you've completed the AQ test, you can access a detailed paid report — a breakdown of your AQ-50 score across all five domains, with clinical context and guidance on what your results mean. You'll also get access to the NeuroDirect Hub, where you can track your screening results, access resources, and revisit your scores over time.
- Connect with a Specialist: Use our Find a Specialist tool to locate autism-affirming professionals near you who can guide you through a formal assessment.
- Learn More About Autism: Browse our resources and articles for practical advice and lived-experience perspectives, or visit the NHS autism overview for a clinical summary.
- Consider Related Tests: The AQ test is one measure. Taking additional tests like the RAADS-R or CAT-Q alongside it gives a broader picture of your neurodivergent profile.
Other Tests You Might Find Helpful
The AQ test gives you a strong baseline, but pairing it with a second screening tool can give you a much fuller picture of your neurodivergent profile.
The RAADS-R covers 80 questions across four domains and is specifically designed for adults who may have been missed or misdiagnosed in childhood. A natural companion to the AQ test.
CAT-Q (Camouflaging Autistic Traits Questionnaire) Explores how you might mask or adapt autistic traits in social situations — particularly useful if your AQ test score feels lower than expected.
Empathy Quotient (EQ) Test Assesses your ability to recognise and respond to emotions. Often taken alongside the AQ test to build a broader picture of social and emotional processing.

Frequently asked questions
Common questions about the AQ test, how it’s scored, and what your results mean.
1. What does the AQ test measure?
The AQ test evaluates five areas commonly associated with autistic traits: social communication, attention switching, attention to detail, imagination, and communication style. The AQ-50 covers all five domains across 50 questions.
2. How accurate is the AQ test?
The AQ test has been widely used in both research and clinical settings since its development at the University of Cambridge. It is a validated screening tool, though accuracy depends on honest self-reporting. A high AQ test score should always be followed up with a professional evaluation rather than treated as a diagnosis.
3. What is a high score on the AQ?
A score of 32 or above on the AQ-50 is considered clinically significant and is common among autistic adults. Scores between 26 and 31 indicate moderate autistic traits worth exploring further.
4. Can the AQ test diagnose autism?
No. The AQ test is a screening tool, not a diagnostic instrument. A formal autism diagnosis can only be made by a qualified specialist following a comprehensive assessment.
5. How long does it take to complete the AQ?
Most people complete the full AQ-50 in 10–15 minutes. Your score is available instantly once you finish.
6. Is the AQ test the same as the AQ-50?
The AQ test was designed for adults of average or above-average intelligence. It is not validated for use in children — separate versions exist for younger age groups. The AQ-50 is most commonly used as a first-step screening tool for adults who are exploring whether their traits align with autism.
7. Who is the AQ test designed for?
Yes. The AQ test and the AQ-50 refer to the same tool. The “50” refers to the number of questions in the full questionnaire. You may also see it referred to as the Autism Spectrum Quotient or AQ test online — these all describe the same validated screening instrument developed at Cambridge.
8. What's the difference between the AQ test and the RAADS-R?
Both are well-validated adult autism screening tools, but they measure different things. The AQ test is shorter (50 questions) and focuses on five trait domains. The RAADS-R covers 80 questions across four domains with a particular focus on adults who may have masked their traits or been missed in childhood. Many people find it useful to take both.
9. Can I take the AQ test if I already have an autism diagnosis?
Yes. Many diagnosed adults take the AQ test to better understand their trait profile across the five domains, or to track how they present over time. Your AQ-50 score can also be a useful reference point when speaking with specialists.
10. Is the AQ test free?
Yes — the full 50-question AQ test is completely free to take on NeuroDirect, with no account or sign-up required. Once you’ve completed the test, you can optionally unlock a detailed paid report with a full breakdown of your AQ-50 score across all five domains and guidance on next steps.
