Meaning of RAADS-R Scores
Score interpretation based on Hegarty et al. (2025) research findings
0-64: Below Threshold
Low likelihood of autism. Scores in this range are typical of non-autistic individuals. The 2025 research confirms that scores below 65 have high specificity for ruling out autism spectrum disorder.
65-105: Neurodivergent Signal
Gray zone with lower specificity. Scores in this range may indicate autism traits, but could also reflect ADHD, anxiety disorders, or trauma-related conditions. Further professional evaluation is strongly recommended to differentiate between conditions.
106-139: Consistent with Autism
Strong indication of autism spectrum traits. Research shows specificity returns to 81% at this threshold. Scores in this range are consistent with an autism spectrum profile and warrant professional diagnostic evaluation.
140+: Pronounced Traits
Very high correlation with autism spectrum disorder. False positives are rare at this level. Individuals scoring 140 or above show pronounced autism traits and should consider seeking formal diagnostic assessment.
Maximum Score: 240
The absolute maximum score attainable on the RAADS-R scale. Each of the 80 questions can score 0-3 points.

What is a normal RAADS-R score?
Scores below 65 are typically found in non-autistic individuals. The average score for people with autism is around 130. Scores of 65+ suggest autism traits worth discussing with a healthcare provider.
How accurate is the RAADS-R test?
Research shows the RAADS-R has 97% sensitivity (correctly identifying autism) and 100% specificity (correctly ruling out non-autism). It's considered one of the most accurate self-report autism screening tools.
