Free ADHD Test for Adults
This is a free online ADHD test for adults based on the World Health Organization's Adult ADHD Self-Report Scale (ASRS v1.1) — the same screening tool clinicians use worldwide. There are 18 questions, it takes about 5 minutes, and you get your scored result instantly. No email, no sign-up, and your answers never leave your browser.
What is the ASRS v1.1 ADHD screening scale?
The Adult ADHD Self-Report Scale is a questionnaire developed by the World Health Organization (WHO) and Harvard Medical School researchers to screen adults for ADHD symptoms. It contains 18 questions split into two parts: the first 6 questions (Part A) are the most predictive — they form the classic ADHD screener score — and the remaining 12 (Part B) cover inattention, hyperactivity, and impulsivity in more depth. Adults who score high on Part A are more likely to meet the criteria for adult ADHD, so the scale is often the first step toward a professional diagnosis.
Is this online ADHD test accurate?
Online ADHD tests vary widely in quality, which is why this one uses the ASRS v1.1 rather than an invented quiz. The ASRS is the most widely validated adult ADHD screening questionnaire and scores your answers against WHO research thresholds. That said, it is a screening tool, not a diagnosis: only a qualified clinician — a GP, psychologist, or psychiatrist — can formally diagnose adult ADHD. Think of your result as a reliable signal of whether a professional evaluation is worth your time.
ADHD in adult women
Many adult women only discover ADHD in their 30s or 40s, after years of being labelled disorganised, anxious, or "scattered". ADHD in girls and women is frequently inattentive rather than hyperactive, so it hides behind daydreaming, forgetting, and quiet overwhelm instead of obvious behaviour problems. If you are an adult woman wondering whether your lifelong focus struggles, rejection sensitivity, or constant mental clutter could be ADHD, this ASRS-based screener is a good first check.
Inattentive vs hyperactive ADHD
The 18 questions map onto the two core ADHD symptom domains. Inattentive ADHD shows up as losing focus mid-task, losing things, missing details, and forgetting appointments. Hyperactive-impulsive ADHD shows up as restlessness, fidgeting, interrupting, and acting before thinking. Many adults have a mix of both. Your results break your score down by domain so you can see where your symptoms cluster.
What to do after the test
If your Part A score is 4 or more, bring your results to a qualified healthcare professional and ask for an adult ADHD evaluation. Sharing your scored questionnaire makes that first appointment faster and more productive — many clinicians start their own assessment with exactly this scale.
Frequently asked questions

About 5 minutes. There are 18 questions with five answer options each, and you can go back to change any answer.
Is this ADHD test a diagnosis?
No. The ASRS v1.1 is a WHO screening scale. A positive screen means ADHD symptoms are likely and a professional evaluation is recommended — it is not a diagnosis.
Can adults take this ADHD test?
Yes — this test is designed for adults. The ASRS was validated specifically for adult ADHD, not for children or teens.
