About the free online AuDHD test for adults
We built audhdtest.net because the adults most likely to benefit from an AuDHD self-assessment are the ones least likely to afford or access one. Our mission is to keep the free online AuDHD test genuinely free, science-informed, and friendly enough that the experience itself feels like progress.
What is AuDHD, and why a dedicated test?
AuDHD is the informal name for the overlap of autism and ADHD in the same person — a combination research suggests affects the majority of autistic adults. Standard single-condition screeners are built to spot one neurotype at a time, which is exactly how the second one gets missed. A dedicated AuDHD test looks at how the two interact, so the profile is harder to overlook.
Our story — building a free online AuDHD self-assessment
The project started in 2024 after one of our writers waited 18 months for a public adult ADHD assessment, only to be told her autism traits were “probably masking everything else.” We wanted a tool that took the AuDHD overlap seriously from the very first question.
How the AuDHD test is built (ASRS-v1.1 + AQ-10)
Our item bank draws on the AQ-10, ASRS-v1.1, and qualitative interviews with late-identified AuDHD adults. A small advisory group of clinical psychologists and lived-experience reviewers checks every wording change before it goes live, so the free online AuDHD test stays both clinically sensible and human to read.
Who the free AuDHD test is for
The test is written for adults aged 16 and up. It is especially useful for late-identified women, non-binary people, and high-masking adults whose traits slip past traditional screeners, as well as anyone already diagnosed with autism or ADHD who suspects a second neurotype is in the mix.
Editorial & clinical review standards
Every question is reviewed for plain language and clinical sense before publication, and we re-check the item bank against current screening literature on a regular schedule. The free online AuDHD test is an educational self-reflection tool — it is never presented as a diagnosis, and results always point toward qualified professional evaluation.
What we won't do
We will never sell your responses, ask you to pay for a “premium” AuDHD test result, or pretend a screener is a diagnosis. If we ever change that, we'll tell you on this page first.
