An ADHD test for children is best understood as a structured way of organising what you already notice. Rather than a single pass-or-fail answer, a good screening asks about specific, observable behaviours across the settings your child lives in — home, school, clubs — and then compares the pattern with the criteria clinicians use.
That distinction matters. A screening can tell you whether the pattern you are seeing is consistent with ADHD and strong enough to be worth a professional opinion. Only a qualified clinician, working from multiple sources of information, can diagnose.
What a screening actually measures
Most parent-report tools, including ours, are built around the two symptom clusters described in the DSM-5 diagnostic criteria: inattention, and hyperactivity/impulsivity. A third group of questions looks at impact — whether the behaviours are getting in the way of learning, friendships, family life or self-esteem.
- Frequency: how often a behaviour happens, not whether it has ever happened.
- Persistence: whether it has been present for six months or more.
- Pervasiveness: whether it shows up in more than one setting.
- Impairment: whether it causes real difficulty, not just inconvenience.
From noticing to next step

Why impact matters more than any single behaviour
Almost every child is distracted, restless or impulsive sometimes. Clinicians look for a pattern that is out of step with the child's age, present across settings, and causing genuine difficulty. This is why two children with similar behaviours can reach very different conclusions: one is coping, the other is not.
How a screening profile is built

Focus, follow-through, organisation, forgetfulness
Restlessness, interrupting, waiting, physical activity
School, friendships, home, self-esteem
What happens after the screening
- 1Save or print your profile. A written summary is far more persuasive than a verbal description in a ten-minute appointment.
- 2Ask school for their view. A teacher's account of the same behaviours strengthens any referral.
- 3Book a GP appointment and ask specifically about a referral pathway for ADHD assessment.
- 4If waiting times in your area are long, ask what a private assessment would involve and whether the outcome can be shared with the NHS.
Questions a full assessment will cover
A proper assessment goes far wider than a questionnaire. Expect a developmental history from birth onwards, school reports and teacher rating scales, questions about sleep, anxiety, mood, hearing and vision, and time spent with your child directly.
Both the NHS overview of ADHD and the NICE guideline NG87 set out what a good UK assessment should include — worth reading before you book anything privately.
Frequently asked questions
- Can an online ADHD test diagnose my child?
- No. An online test is a structured screening. It can show whether the pattern you are describing is consistent with ADHD, but a diagnosis requires a qualified clinician who gathers information from home, school and a direct assessment of your child.
- What age can children be screened for ADHD?
- Screening tools for parents are generally designed for children from around four years old, because before that age high activity levels and short attention spans are developmentally typical. Our screening covers ages 4 to 17.
- How long does the screening take?
- Around eight to ten minutes. It helps to answer based on the last six months rather than the last few days.
