Free ADHD Self-Assessment — Adult ADHD Screening Test
Based on the WHO Adult ADHD Self-Report Scale (ASRS-v1.1). Answer 6 questions to see whether your symptoms are consistent with adult ADHD.
This is a screening tool, not a diagnosis. A high score does not mean you have ADHD — only a qualified clinician can make that determination.
Based on the WHO Adult ADHD Self-Report Scale (ASRS-v1.1). If you are in distress, contact your GP or call 111.
Question 1
How often do you have trouble wrapping up the final details of a project, once the challenging parts have been done?
Could it be more than ADHD?
Research shows that around 40% of people with ADHD also have autism. If you suspect you might have both, a combined ADHD and autism assessment can be quicker and more cost-effective than having two separate assessments.

This screener uses Part A of the WHO Adult ADHD Self-Report Scale (ASRS-v1.1), a 6-question instrument developed by the World Health Organization and validated in multiple clinical studies. It is widely used by GPs and clinicians as a first step in identifying adults who may benefit from a formal ADHD assessment.
A score of 4 or more on this screener has a sensitivity of 68.7% and a specificity of 99.5% for adult ADHD — meaning it is highly specific but not perfectly sensitive. Some people with ADHD will score below 4, particularly women and those with primarily inattentive presentations. Read our guide on ADHD in women for more on how ADHD can present differently.
This tool does not replace a clinical assessment. If your score suggests ADHD symptoms, the next step is to speak to your GP about a referral, or to explore Right to Choose for a free NHS-funded assessment. You can also compare private ADHD clinics if you prefer a faster route.

Frequently asked questions
Can I get assessed for ADHD and autism at the same time?
Yes, several clinics offer combined ADHD and autism assessments. This is often quicker and cheaper than having two separate assessments. Use our Combined ADHD & Autism filter on any city page to find clinics offering this.
What should I do if my score suggests ADHD?
This screener is a starting point, not a diagnosis. If your score is 4 or above, consider speaking to your GP about a referral, or explore the NHS Right to Choose scheme for a free funded assessment with a private clinic.
Is this test the same as a clinical ADHD assessment?
No. This is a screening tool based on the WHO ASRS-v1.1, which helps identify whether your symptoms are consistent with ADHD. A formal diagnosis requires a comprehensive clinical assessment by a qualified psychiatrist or specialist.
