Understanding ADHD in children: signs and support
A child who focuses for an hour on a game and not five minutes on a worksheet is not proving they could if they wanted to. What ADHD is, and what teachers should document rather than diagnose.

ADHD is one of the most common neurodevelopmental conditions of childhood, and one of the most frequently misread. The behaviour is visible; the reason for it is not. A child who cannot stay seated is easy to describe as difficult, and much harder to describe accurately.
What it actually is
ADHD affects the systems that regulate attention, impulse and activity. It is not a matter of intelligence, effort, or upbringing. The same child who cannot hold attention on a worksheet may sustain it for an hour on something absorbing, which is often read as proof that they "could if they wanted to". It is not proof of that. Attention regulation is not the same as attention capacity.
Signs that warrant a conversation
- Difficulty sustaining attention on tasks that are not immediately rewarding, across more than one setting.
- Frequently losing things needed for daily activities, over months rather than a bad week.
- Restlessness or difficulty remaining seated when the situation requires it.
- Acting before thinking: interrupting, blurting, difficulty waiting a turn.
- Work that is well understood but not finished.
Two qualifiers matter: the pattern must appear in more than one environment (school and home, not school alone), and it must be causing real difficulty. Every child does some of this some of the time.
What helps
Structure does more than reminders. Shorter work segments with clear endpoints, instructions given one at a time, a visible checklist, and predictable routines all reduce the load on the system that is under strain. Movement breaks are not indulgence; for many children they are what makes the next segment possible.
What parents and teachers should not do
Do not diagnose. A questionnaire found online is not an assessment, and a label applied informally is hard to remove. What a teacher can do is document specifics (what happens, when, how often, in which lessons) and give that record to the family to take to a qualified clinician. That documentation is genuinely useful; a verdict is not.

Frequently asked questions
If a child can focus on things they enjoy, do they really have ADHD?
That pattern is common and is not evidence against it. ADHD affects attention regulation, not attention capacity: the ability to direct attention to something that is not immediately rewarding is the part under strain.
When is a pattern of behaviour worth raising with a family?
When it appears in more than one environment (school and home, not school alone), persists over months rather than a bad week, and causes real difficulty. Every child does some of this some of the time.
Can a teacher say a child has ADHD?
No. An online questionnaire is not an assessment and an informal label is hard to remove. Document specifics (what happens, when, how often, in which lessons) and give that record to the family for a qualified clinician.
