Meaning of RAADS-R Scores
Score ranges draw on the original RAADS-R validation study (Ritvo et al., 2011) and a 2025 NovoPsych technical analysis. The RAADS-R is a screening tool and cannot diagnose autism.
0-64: Below Threshold
Scores below 65 are below the original RAADS-R research threshold and are associated with a lower likelihood of autism based on the available research. A score below this threshold does not rule out autism, particularly when clinical history or other information raises concern.
65-105: Gray Zone
A gray zone. Scores in this range may reflect autistic traits, but can also be associated with ADHD, anxiety, depression or trauma-related experiences. A comprehensive evaluation by a qualified professional can help clarify what is contributing to the score.
106-139: Elevated Autistic Traits
RAADS-R results in this range are associated with elevated autistic traits and may warrant comprehensive assessment. In a 2025 NovoPsych technical analysis, this range showed approximately 81% specificity when evaluated against AQ-based criteria, which is psychometric data rather than evidence of a diagnosis. The RAADS-R on its own cannot diagnose autism.
140+: Pronounced Traits
Higher RAADS-R scores indicate greater endorsement of autistic traits. A high score may provide a reason to pursue a comprehensive autism evaluation, but it is not diagnostic and should be interpreted in the context of developmental history, clinical interview, and other relevant information.
Maximum Score: 240
The absolute maximum score attainable on the RAADS-R scale. Each of the 80 questions can score 0-3 points.
Frequently Asked Questions About Autism Testing
Common questions about our free autism test
Is there an online test for autism in adults?
Yes. The RAADS-R (Ritvo Autism Asperger Diagnostic Scale-Revised) is a research-based self-report screening questionnaire designed for adults. Our free online version uses the published RAADS-R items to help you reflect on autism spectrum traits. It is a screening tool and cannot diagnose autism.
How reliable are online autism tests?
In the original RAADS-R validation study, a score of 65 or above showed high sensitivity and specificity in that study sample. Subsequent research in clinical populations has found substantially more false-positive results, so these figures should not be interpreted as the likelihood that an individual user has or does not have autism. Scores between 65 and 105 in particular are also seen in adults with anxiety, ADHD or other conditions. No online test can provide a diagnosis; the RAADS-R is a screening tool that can indicate whether a comprehensive assessment may be worthwhile.
Is this autism test completely free?
Yes, our basic RAADS-R autism test is completely free. You'll receive your total score and dimensional breakdown at no cost. We also offer an optional paid, AI-generated report for those who want a more detailed written summary; it is not written or reviewed by a clinician.
Can I self-diagnose autism with this test?
No. This test is a screening tool, not a diagnostic instrument. A formal autism diagnosis requires evaluation by qualified healthcare professionals. This test can help you understand if further assessment might be beneficial.
What is a normal RAADS-R score?
Scores below 65 are below the original RAADS-R research threshold. In the original validation study, autistic participants scored around 130 on average. A score of 65 or above indicates more endorsement of autistic traits and may be worth discussing with a qualified healthcare provider; it is not a diagnosis.
How accurate is the RAADS-R test?
In the original RAADS-R validation study, a score of 65 or above showed high sensitivity and specificity in that study sample; subsequent research in clinical populations has found substantially more false-positive results. A 2025 NovoPsych technical analysis proposed updated interpretive ranges for clinical use, including 106-139 and 140+. In that analysis, these thresholds showed approximately 81% specificity when evaluated against AQ-based criteria. These findings should be viewed as psychometric/clinical-utility data rather than evidence that a particular RAADS-R score diagnoses autism. A score is a starting point for reflection, not a diagnosis.
