About & Methodology
Our Mission
We believe that autism screening should be accessible to everyone. Many people live with undiagnosed autism—experiencing social exhaustion, sensory overload, or a feeling of being "different" without understanding why. For many, especially adults and women who may have been missed in childhood, the path to self-discovery begins with a moment of recognition.
Our free self-assessment is designed to facilitate that moment. It provides a structured framework for evaluating your own experiences against clinical criteria, giving you clear results you can bring to a healthcare provider. We do not charge for the assessment, we do not require an account, and we do not sell your data.
Who Built This
Jack Squire — Founder
Top 1% SEO Expert on Upwork · Founder of Outrider Digital · Neurodivergent Advocate
Jack built Free Autism Test and Free ADHD Test to make neurodivergent screening accessible to everyone. As someone who thinks differently, he understands the value of self-discovery and believes no one should have to pay to learn how their brain works. He also builds productivity tools for neurodivergent individuals through his projects.
Our Screening Tools
We offer four clinically validated autism screening instruments, each developed by leading research institutions and published in peer-reviewed journals. We did not create these tests — we make them freely and privately accessible.
AQ-10 (Autism Spectrum Quotient — 10 items)
Developed by Allison, Auyeung, and Baron-Cohen (2012) at the Autism Research Centre, University of Cambridge. A rapid screening using 10 questions with a 4-point agreement scale (Definitely Agree to Definitely Disagree). A score of 6 or above suggests further assessment is warranted. Sensitivity: approximately 88%.
AQ-50 (Autism Spectrum Quotient — 50 items)
The full version of the Autism Quotient, developed by Baron-Cohen et al. (2001). 50 questions across five domains: Social Skills, Attention Switching, Attention to Detail, Communication, and Imagination. Same 4-point agreement scale. A score of 32 or above suggests clinically significant autistic traits.
RAADS-R (Ritvo Autism Asperger Diagnostic Scale — Revised)
Developed by Dr. Riva Ariella Ritvo et al. (2011), specifically designed for adults who were not identified in childhood. 80 questions across four domains: Social Relatedness, Language, Sensory/Motor, and Circumscribed Interests. Uses a unique lifetime pattern scale ("True now and when I was young" to "Never true"). A total score of 65 or above is clinically significant.
M-CHAT-R (Modified Checklist for Autism in Toddlers — Revised)
A parent-report screening tool for toddlers aged 16 to 30 months, validated by Robins et al. (2014). 20 yes/no questions about the child's behavior. Endorsed by the American Academy of Pediatrics for universal screening at 18 and 24 months.
How Scoring Works
Each screening tool uses its own validated scoring methodology as defined by the original research. We do not modify the scoring algorithms — your results are calculated exactly as described in the published literature. Scores are compared against established clinical thresholds to indicate whether further assessment may be warranted.
Privacy and Data Handling
We take your privacy seriously. Your answers and results are processed entirely in your browser. We do not transmit your assessment data to our servers or any third party. No account is required, and no identifiable data is collected.
Important Limitations
- It is not a diagnosis. A self-assessment cannot replace the clinical judgment of a trained professional.
- It does not account for co-occurring conditions. ADHD, anxiety, and sensory processing disorders can overlap with autism.
- Self-report has limits. Your results depend on your own self-awareness and understanding of the questions.
Next Steps
If your results suggest a high likelihood of autism, we encourage you to seek a formal evaluation if you need access to accommodations, therapeutic support, or further clarity. Use these results as a starting point for a conversation with a qualified professional.
