How reliable are online autism tests?
The RAADS-R has been scientifically validated with high sensitivity (97%) and specificity (100%) in clinical studies. While no online test can provide a diagnosis, the RAADS-R is one of the most reliable screening tools available.
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 optional professional AI analysis for those who want deeper insights.
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 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.
