The UK's most comprehensive free ADHD test

Most free ADHD tests give you a number and nothing else. This one gives you a full profile — with scores, clinical threshold comparisons, and UK-specific guidance on exactly what to do next, including how to use the NHS Right to Choose scheme to access faster assessment.

What makes this test different

Unlike most online ADHD quizzes, this test is adaptive — it adjusts based on your early answers to ask the most relevant follow-up questions. If ADHD traits are indicated, you go deeper. If not, you skip straight to results. This means you only answer what's relevant to you.

It also screens for autism and AuDHD simultaneously — because around 50–70% of autistic people also have ADHD, and many people seeking an ADHD assessment are actually AuDHD. Knowing this before you see your GP could save you years of being assessed for only one condition.

Printable results: Your results page can be printed or saved as a PDF — giving you something concrete to bring to your GP appointment rather than a verbal description of your symptoms.

ADHD in UK adults — what the research says

ADHD affects an estimated 3–4% of UK adults — around 2 million people. The majority are undiagnosed. NHS waiting times for adult ADHD assessment range from several months to several years depending on area, making early identification and GP engagement critically important.

Women are diagnosed on average 10 years later than men. Many adults who grew up before ADHD was widely recognised in the UK were never assessed as children, regardless of how obvious their symptoms were.

Also concerned about autism?
