ADHD in children is not diagnosed by a test the child sits. It is diagnosed by building a case from more than one setting, which is why the process asks so much of parents and of school.
Knowing that in advance changes what you prepare, and preparation is most of what makes an assessment go well.
Why more than one setting is required
The diagnostic criteria require that symptoms are present in two or more settings, typically home and school. [apa-2022-dsm5tr-children]
That requirement does real work, and it is worth understanding rather than resenting.
A child who cannot settle in one particular classroom, with one particular teacher, is telling you something about that classroom. A child who is difficult at home during a period when home is difficult is telling you something about the period. ADHD travels with the child, so it shows up in both places, and requiring both is how the assessment avoids attaching a lifelong label to a situation.
It is also why the school is asked to complete forms, and why an assessment stalls when they are not returned. The ADHD hub covers what the condition involves across the lifespan.
What the assessment actually involves
There is no scan and no blood test. What a specialist puts together is:
A developmental history. When milestones happened, what early years were like, and whether difficulties were present before the point at which they became a problem.
Information from home. Usually structured questionnaires plus a long interview, focused on specific examples rather than general impressions.
Information from school. The same questions asked of people who see the child in a group of peers.
Observation and, where relevant, other explanations ruled out. Hearing, sleep, anxiety and learning difficulties can all produce parts of the picture, and they are checked rather than assumed away.

The checklist bar is deliberately awkward. Those tools are useful for deciding whether to seek an assessment and carry almost no weight inside one.
What guidance says gets offered
The order matters, and it surprises people who arrive expecting medication to be the question.
Under five. NICE guidance recommends an ADHD-focused group parent-training programme as the first-line offer, and states that medication should not be offered to a child under five without a second specialist opinion from a service with expertise in this age group. [nice-ng87-adhd-children]
Five and over. Medication has a defined place, but it sits within a wider plan rather than replacing it. The decision is made with a specialist, and our guide to ADHD medication covers the order it follows and why finding the right dose takes weeks by design.
Parent training is not a comment on your parenting, and it is worth saying plainly because that is how it frequently lands. It is a set of specific techniques for a specific difficulty, in the same way that a physiotherapy programme is not a comment on how you have been walking.
Is this worth raising with school or a doctor?
Tick anything true of your child. This is a reflection prompt rather than a test, it produces no diagnosis, and only a specialist assessment can.
0 of 8 ticked
The first four items are close to the threshold an assessment applies: more than one setting, lasting, marked for age, and genuinely costly. Start with the school special educational needs coordinator and an appointment with a doctor on the same week, and take written examples with dates. Support through school does not wait for a diagnosis.
Inattention, restlessness and impulsivity are ordinary in childhood, which is why degree and duration matter more than presence. If you ticked the last two items in particular, that pattern points at circumstances rather than at ADHD, and it is still worth raising with school.
Nothing here matched. If the concern is more about worry and reassurance-seeking than about attention, that is a different pattern and worth describing to a doctor in those terms.
No screener on this site assesses children, and every screener we publish is written and validated for adults. The hub lists what we cover, and none of it should be used on a child.
What helps while you wait
Waits are long in many countries, and none of the following depends on a diagnosis.
Write things down as they happen. Dates, what was asked of the child, what happened. Assessment runs on specific examples, and six months of them is worth more than any recollection produced on the day.
Ask the school about support now. The special educational needs process responds to need rather than to diagnosis, so a child can get help with seating, instructions, movement breaks and homework without waiting.
Break instructions down. One step at a time, in the order they happen, with eye contact first. Most of what looks like defiance in a young child with attention difficulties is an instruction that was never fully received.
Protect sleep. Insufficient sleep produces inattention and irritability in any child, and it makes everything else harder to read.
Ask about parent training. It is the first-line recommendation for the youngest children in any case, so asking now is not jumping ahead. Our guide to parenting a child with ADHD covers what those programmes teach, and what the trials found held up when the raters were probably blinded.
If you recognise a good deal of this in your own childhood, that is common and worth taking seriously. Our guide to ADHD in women covers why so many parents reach their own assessment through their child’s.
When to seek help
Speak to your doctor, and to the school’s special educational needs coordinator, if attention, activity or impulsivity are marked for your child’s age, have lasted at least six months, appear in more than one setting, and are affecting learning or friendships.
Ask what the local referral route is, since it differs between areas, and ask what support the school can put in place while a referral is pending. Take your written examples with you.
Raise it promptly if your child is being excluded from school, if they are describing themselves as stupid or bad, or if their mood has changed alongside the difficulties, since those are the points at which waiting costs the most.
Go urgently if your child talks about harming themselves or about not wanting to be alive.
How MyFreud can help
Supporting a child through a long wait is its own load, and it is usually the parent’s own state that goes unrecorded. MyFreud gives you daily mood tracking that takes seconds, which is a small way of noticing what this is costing you as well as them.
