ADHD

Attention, impulse and activity are shaped as much by the situation as by the child. This guide looks at what ADHD is, what it is not, and what actually helps in a mainstream primary classroom and at home.

OverviewFor parents

What ADHD is

ADHD — attention deficit hyperactivity disorder — is a neurodevelopmental condition. The NHS describes it as a difference in how the brain develops and works, present from early childhood rather than something a child acquires. It is usually described in terms of attention, impulsivity and activity level, and it often shows up in the everyday business of starting things, staying with them, waiting, and switching.

The name is not a very good description. Children with ADHD do not lack attention; attention is harder to direct and hold where it is needed, and can be extremely difficult to pull away from something absorbing. Interest, urgency, novelty and how a task is set up all change what is possible on a given day — which is exactly why the same child can look so different in two lessons.

One way to hold it

It is less "can they pay attention?" and more "how much does this situation ask of the systems that direct attention, hold information and delay a response — and how much of that can we take off the child?"

OverviewFor parents

What you might notice

These are observations, not a checklist and not a test. Every child does some of these. What matters is how often, how much it gets in the way, and whether it happens across different settings rather than only in one.

  • Instructions get lost part-way through, or only the last part is done.
  • Starting is the hard bit — even for things they want to do.
  • Deep, sustained absorption in something interesting, alongside real difficulty with anything that is not.
  • Movement: fidgeting, wandering, needing to be doing something with their hands or body.
  • Answers arrive before the question is finished; waiting a turn is genuinely uncomfortable.
  • Belongings, coats, bags and homework go missing regularly.
  • Feelings arrive fast and large, and pass quickly.
  • Mornings, bedtimes, homework and transitions are the hardest parts of the day.
  • Exhaustion or distress after school, when the effort of holding it together stops.
Many children do these things

Attention, activity and impulse control develop over years and vary hugely between children of the same age. Difficulty with them is common and is not, in itself, ADHD. Tiredness, anxiety, a language difficulty, hearing, sensory differences, unmet learning needs and simply finding the work too hard or too easy can all look similar from the outside.

MoreFor parents

Strengths are part of the picture

This is not a consolation paragraph. Adults who work well with children with ADHD tend to be the ones who know what the child is good at, because that is where the leverage is. Many children with ADHD bring energy, humour, willingness to try things, quick lateral thinking, deep engagement with what interests them, directness, and a strong sense of fairness. Some are noticing things nobody else in the room noticed.

None of this is universal, and none of it cancels out genuine difficulty. But a child who only ever hears about what they get wrong will draw conclusions about themselves that are much harder to undo than any of the practical problems.

OverviewFor parents

What differs between children

Presentation varies a great deal. Some children are visibly restless; others are quietly inattentive and drift through school without anyone raising a concern. It can look different at different ages, and it can look different at home and at school — which sometimes leads to each side thinking the other is exaggerating or being too soft. Usually both are describing what they genuinely see.

Context does a lot of work. Structure, interest, how tired a child is, how much noise there is, how clear the expectation is, how long the wait is, and whether an adult is nearby all change what happens. That is not evidence that a child could do it all the time if they tried harder; it is evidence that demands and environments matter.

AssessmentFor parents

Assessment and diagnosis: what it does and does not tell you

Only a suitably qualified health professional can diagnose ADHD. In England, that is usually a paediatrician or a specialist child mental health service, following a referral — often through your GP or, in some areas, via school. NICE NG87 sets out how recognition, referral and diagnosis should work, and assessment involves information from more than one setting, which is why school is asked to contribute.

  • A diagnosis can explain a pattern, open access to some services, and change how adults respond.
  • A diagnosis does not describe your child's strengths, or say what should happen in the classroom.
  • There is no single test. Assessment gathers information over time, from home and school.
  • Waiting lists in many areas are long. School support should not wait for the outcome.
  • A decision not to diagnose does not mean nothing is wrong or that you imagined it.
Support does not need to wait

Under the SEND Code of Practice, schools identify and respond to need. They do not need a diagnosis to make adjustments, and they should not be waiting for one.

OverviewFor parents

What helps at home

One instruction at a time

What it is: say one thing, wait for it to happen, then say the next. Why: it removes the memory step, which is often where things fall apart rather than at the willingness step.

Make the routine visible

What it is: a short picture or word list for mornings and bedtimes, in the place it happens. Why: the list does the remembering, and it becomes the thing being argued with rather than you.

Shorten the gap between doing and feedback

What it is: notice and say the thing now, not at the end of the week. Why: distant rewards do very little; immediate, specific acknowledgement does more.

Warn before you switch

What it is: a couple of minutes' notice before stopping something absorbing. Why: stopping mid-flow is genuinely hard, and warning converts an ambush into a plan.

Cut the homework into visible pieces

What it is: three short bursts with a clear finish line rather than one open-ended session. Why: the size of the task is often the barrier, not the content.

Let movement happen

What it is: a run, a scooter, jobs around the house, doing homework standing up. Why: many families find it helps, and it costs nothing. Be honest that this is practical wisdom rather than strong research evidence.

Protect the relationship

What it is: some part of the day that is not about instructions, correction or school. Why: children with ADHD receive far more negative feedback than their peers over a childhood, and that accumulates.

About the things you will see advertised

There is an enormous market around ADHD, and much of it is not evidence-based. We are not telling you to avoid everything — a fidget or a timer that helps your child is not a problem. We are saying be careful about what you spend money and hope on.

  • Fidget toys and sensory gadgets: some children find them useful, others find them a distraction. Evidence for improved learning is limited and mixed.
  • Movement breaks: widely used and often sensible, but the research base for improved attainment is weak. Judge it child by child.
  • Timers and visual countdowns: helpful for many children as a way of making time visible. Low cost, low risk.
  • "Dopamine hacks": a marketing phrase, not a clinical one. Treat the underlying advice on its own merits.
  • Supplements and special diets: NICE does not recommend eliminating foods or using supplements as a general treatment for ADHD. Speak to a health professional before restricting a child's diet.
  • Brain-training programmes: evidence of improvement in the trained tasks, little evidence that it transfers to classroom learning.
  • Anything promising to fix, cure or reverse ADHD: not supported by evidence.
On medication

Medication is a clinical decision, made with a specialist, and it is not something we advise on. NICE NG87 and the NHS set out when it is considered, alongside other support. It is neither a failure nor a shortcut, and it is not a substitute for adjustments at school.

MoreFor parents

Working with school

  • Ask for a conversation with the class teacher first, then the SENDCO if you need to.
  • Describe specific situations rather than general worry: which lesson, which part of the day, what happens.
  • Ask what they see — it may differ from home, and both pictures are needed.
  • Ask what is being put in place, and when you will review whether it is working.
  • Share what works at home; a lot of it transfers.
  • Ask how they will keep you informed without every message being about something going wrong.

If you are worried enough to want an assessment, your GP is usually the route, and school can contribute information. Say clearly what you are asking for and why.

Evidence & sources

The label is the start of the conversation, not the end of it

A diagnosis tells you something real, and it can unlock understanding, services and self-knowledge. What it does not tell you is what this child needs on Tuesday morning in maths. Two children with the same diagnosis can need almost opposite things. The useful sequence is always: this child's strengths and profile → what is actually getting in the way → in which situations → what we can change or provide.

What this guide is, and is not

This is an educational resource, not a clinical one. Nothing here identifies, diagnoses or rules out ADHD — that requires a specialist assessment through the NHS or an equivalent qualified service. Many children find attention, activity or impulse control difficult without having ADHD, and some children with ADHD show none of the more obvious signs. We also do not give medication advice: where treatment is relevant, NICE NG87 and the NHS are the sources to follow.
