ADHD Test Online is a free online ADHD screening website for adults and children. It is not a course platform in the traditional sense; it is closer to a “mental health education + self-help questionnaire tool.” The adult test references the WHO ASRS-v1.1, while the children’s test references SNAP-IV, helping users structure and record everyday behaviors related to attention, organization, impulsivity, hyperactivity, task follow-through, and more.
The site offers two paths: an adult ADHD Test and a children’s SNAP-IV Rating. The adult questionnaire has 18 questions and takes about 5–7 minutes; the children’s questionnaire has 26 questions and takes about 8–10 minutes. The tests can be completed in a mobile, tablet, or desktop browser, with progress automatically saved via the browser’s local storage. Results summarize score ranges, highlighted areas, and possible next steps in plain language, but the site repeatedly emphasizes that screening is not a diagnosis. A formal assessment still requires a qualified professional to consider medical history, functional impairment, environmental context, and other possible explanations.
Pricing is very clear: it is free to use, with no registration, no email required, and no paid results page. Privacy design is one of its strengths: test answers and results are processed locally in the browser, not stored on servers, and screening responses are not sold. However, the site also states that it uses analytics and Adsterra ad scripts, which may process technical data such as page views, device information, or browser information. Users who are highly sensitive about privacy should still pay attention to this.
Its advantages are a low barrier to entry, a short process, clear language, and references to commonly used screening questionnaires. It also provides educational content on ADHD symptoms, types, support options, school/work accommodations, crisis help, and more, making it suitable for initial learning. The downsides are also clear: it does not provide clinical diagnosis, treatment advice, or personalized courses; it currently supports only English and Spanish; disclosure about the operating organization, professional review team, and commercial background is limited; and the use of ad scripts may reduce trust for some users.
It is suitable for adults who want to first organize their ADHD-related experiences, as well as parents, teachers, and caregivers who want to record behavioral patterns in children or adolescents. If users plan to consult a doctor, therapist, school support staff, or coach, the results can be used as one piece of communication material. The text does not provide information about access from mainland China, so its availability is unknown. Since it does not support Chinese, there is also a language barrier for Chinese-speaking users.
