Many children are energetic, forgetful or easily distracted at times. They may struggle to sit through a long lesson, lose their belongings or become absorbed in something they enjoy. These behaviours do not automatically mean that a child has attention deficit hyperactivity disorder.
ADHD is a neurodevelopmental condition associated with persistent difficulties involving attention, activity levels and impulse control. The pattern is more significant than would usually be expected for the child’s age, appears across important areas of life and causes genuine difficulty at school, at home or in relationships.
Recognising possible signs can help families seek support, but parents should not try to diagnose ADHD from a checklist. Sleep problems, anxiety, autism, learning difficulties, hearing problems and stressful experiences can produce similar behaviours. A proper assessment considers the child’s development and gathers information from more than one setting.
This guide explains what early signs can look like, how ADHD may present differently between children and where families can seek help in the UK.
What ADHD can look like in children
ADHD is commonly associated with inattention, hyperactivity and impulsivity. A child may mainly experience difficulties with attention, mainly show hyperactive and impulsive behaviour, or have a combination of both.
Possible signs of inattention include:
- being easily distracted by sounds, movement or unrelated thoughts;
- finding it difficult to listen to or follow instructions;
- starting tasks but repeatedly failing to finish them;
- losing school equipment, clothing or personal belongings;
- forgetting routines, messages, homework or deadlines;
- making frequent mistakes because important details are missed;
- avoiding tasks that require sustained mental effort;
- appearing not to listen even when someone is speaking directly to them.
Possible signs of hyperactivity and impulsivity include:
- frequent fidgeting, tapping or movement;
- leaving a seat when remaining seated is expected;
- talking excessively or making frequent noises;
- interrupting conversations or calling out answers;
- finding it unusually difficult to wait for a turn;
- acting before considering what may happen next;
- appearing constantly restless or “on the go”;
- becoming overexcited and struggling to slow down.
Individual behaviours on this list are common in childhood. They become more suggestive of ADHD when they form a persistent pattern, are noticeably greater than expected for the child’s developmental stage and interfere with everyday functioning.
The NHS provides an overview of ADHD in children and young people, including common signs, assessment and treatment.
How signs may change with age
ADHD can look different as children grow because the demands placed on their attention, organisation and independence change.
Early years and infant school
Young children are naturally active and still learning how to wait, listen and manage strong emotions. Possible ADHD traits tend to stand out because they are more frequent, intense or difficult to manage than similar behaviour among children of the same age.
A child may move constantly, climb in inappropriate situations or find group activities unusually difficult. They may hear the first part of an instruction but lose track before completing it. Waiting in a line, taking turns or moving calmly between activities may require much more adult support than expected.
Assessment in very young children requires particular care because development varies widely. Professionals will consider whether behaviours persist over time and whether they appear in nursery, school and home environments.
Later primary school
As work becomes more structured, difficulties with attention and organisation may become clearer. A child might repeatedly forget reading records, homework or PE equipment. They may understand a subject well during discussion but produce rushed or incomplete written work.
Parents and teachers sometimes describe a puzzling gap between ability and performance. The child may complete a complex task one day but appear unable to begin a similar one the next. This inconsistency can be mistaken for laziness or lack of effort.
Impulsivity may also affect friendships. The child might interrupt games, become impatient, react quickly to perceived unfairness or struggle to recognise when other children need space.
Secondary school
The move to secondary education places greater demands on planning and working memory. Pupils must manage different teachers, classrooms, books, deadlines and homework systems.
Possible signs include persistent lateness, missed deadlines, lost equipment and last-minute work despite repeated reminders. A pupil may have difficulty estimating how long tasks will take or begin revising only when the pressure becomes urgent.
Hyperactivity may become less physically obvious with age. Instead of running or climbing, a young person may experience internal restlessness, frequent fidgeting, excessive talking or a strong need for stimulation.
Our guide to preparing for secondary school over the summer includes practical advice on routines, organisation and transition.
Why ADHD can be missed in girls and quieter children
ADHD is sometimes overlooked when a child is not disruptive. Girls and children with a mainly inattentive presentation may appear quiet, dreamy, anxious or disorganised rather than visibly hyperactive.
They may spend lessons trying hard to appear attentive while missing instructions, losing track of work or relying on friends to understand what is happening. Perfectionism can sometimes hide the difficulty because the child invests an excessive amount of time and energy in keeping up.
Some children also mask their difficulties at school. They may remain compliant throughout the day and then become exhausted, irritable or emotionally overwhelmed after returning home. This difference between school and home does not necessarily mean that either the parent or teacher is mistaken.
Possible signs worth discussing include:
- frequent daydreaming or appearing mentally absent;
- taking much longer than expected to complete ordinary tasks;
- repeatedly forgetting instructions and belongings;
- high anxiety about making mistakes;
- difficulty maintaining friendships despite wanting to fit in;
- exhaustion or emotional outbursts after school;
- working very hard while making less progress than expected.
Share the complete picture with the school and healthcare professionals, including what happens before school, during homework and after the effort of managing the school day.
Other difficulties that can resemble ADHD
ADHD cannot be confirmed through one behaviour, questionnaire or short appointment. Several other factors can affect attention, activity and emotional regulation.
Poor sleep can cause forgetfulness, irritability and difficulty concentrating. Anxiety may make a child restless or mentally preoccupied. Dyslexia and other learning difficulties can lead to avoidance when tasks repeatedly feel too hard.
Autistic children may struggle with transitions, sensory overload or executive functioning. Hearing and sight problems can make a child appear not to listen. Trauma, bereavement, bullying and major family changes can also alter behaviour and concentration.
Some children have ADHD alongside another condition. Assessment is therefore not simply about deciding whether ADHD is present. It should also consider the child’s wider development, health, learning and emotional wellbeing.
Parents can review healthy sleep habits for school-aged children and the signs of school anxiety and avoidance when considering what else may be affecting concentration.
Our guides to understanding autism in schools, dyslexia in schools and neurodiversity in the classroom provide more information about related needs.
What parents can do at home
Families do not need to wait for a diagnosis before using strategies that make daily life more manageable. The most useful changes often reduce the demands on memory, organisation and self-control rather than repeatedly telling the child to try harder.
Create predictable routines for mornings, homework and bedtime. A written checklist or visual schedule can be more effective than several spoken reminders because the child can return to it without relying on working memory.
Give one clear instruction at a time. Gain the child’s attention, explain the immediate action and ask them to repeat it back where appropriate. Long chains of instructions may be lost even when the child appears to be listening.
Break larger tasks into short, visible steps. Instead of saying “get ready for school”, the routine might involve getting dressed, eating breakfast, brushing teeth, packing a water bottle and putting on shoes.
During homework, agree on one manageable task and use planned movement breaks. Helping Your Child With Homework Without the Stress explains how to support concentration without completing the work for them.
Praise specific effort and strategies. A comment such as “You checked the list and packed everything without another reminder” is more useful than general praise because it identifies the behaviour the child can repeat.
Try not to treat every difficulty as deliberate disobedience. Boundaries remain important, but repeated punishment is unlikely to teach a skill the child does not yet have. Consider what support, reminder or environmental change would make success more achievable.
Talk to the school and ask what it has observed
Your child’s teacher and the school’s special educational needs coordinator can provide valuable information. They see the child alongside peers and can observe attention, organisation, learning, behaviour and friendships in a structured setting.
Arrange a conversation rather than trying to resolve a complex concern during collection time. Describe what you have noticed at home and ask whether similar patterns appear at school.
Useful questions include:
- Does my child regularly miss or forget instructions?
- How long can they usually remain focused?
- Is there a difference between subjects or types of activity?
- Do they complete work that reflects their understanding?
- How do they manage transitions and unstructured times?
- Are there concerns about friendships or emotional regulation?
- Which classroom strategies have already been tried?
The school may introduce support such as visual instructions, seating away from distractions, shorter task sections, movement breaks, organisational check-ins or additional help with homework systems.
Support should respond to the child’s needs rather than being delayed automatically until a diagnosis is received. A diagnosis can provide useful clarity, but schools can identify special educational needs and make suitable provision based on observed difficulties.

How to seek an ADHD assessment in the UK
Referral arrangements vary across the UK and between local NHS services. Depending on where you live, the initial route may involve your GP, school SENCO, community paediatrics, a neurodevelopmental service or Child and Adolescent Mental Health Services.
Start by speaking to the school and checking the referral process used in your area. You can also contact your GP, particularly when the difficulties affect several areas of life or there are concerns about sleep, anxiety, mood or physical health.
A referral may require information from both parents and school. Local services can have different acceptance criteria, so the professional making the referral may ask for evidence that difficulties are persistent, occur in more than one setting and affect everyday functioning.
Waiting times can be lengthy in some areas. Ask what support is available while the referral is being considered and whether the school can review its existing adjustments.
Families in England may hear about NHS patient-choice arrangements or privately provided NHS assessments. Eligibility and available providers can change, and local pathways differ. Discuss current options with your GP or local integrated care board rather than relying on general advice from social media.
A private assessment is another option for some families, but it can be expensive and the quality of services varies. Check that the clinician is appropriately registered, has specific expertise in diagnosing ADHD in children and follows NICE guideline NG87 on ADHD diagnosis and management.
Before paying, ask what the assessment includes, whether school information will be gathered, what follow-up is provided and how recommendations or medication will be coordinated with NHS and school services.
What happens during an ADHD assessment?
There is no single test that can diagnose ADHD. NICE states that diagnosis should be made by an appropriately qualified healthcare professional with training and expertise in ADHD.
The assessment normally considers:
- the child’s developmental and medical history;
- current concerns at home, school and in relationships;
- information from parents, carers and teachers;
- the age at which difficulties became noticeable;
- how symptoms affect education and everyday functioning;
- other conditions or circumstances that may explain or contribute to the difficulties.
Parents and teachers may be asked to complete standardised questionnaires. These can support the assessment, but questionnaire scores alone should not determine the diagnosis.
The professional may speak directly with the child, observe behaviour and review school reports or previous assessments. Hearing, vision, sleep, mood, learning and physical health may also be discussed.
Some services use computer-based attention or movement assessments. These may provide additional information but do not replace a full clinical assessment or information from several settings.
The process should consider the child’s strengths as well as their difficulties. A diagnosis is not intended to reduce a child to a list of symptoms. It should help the family and professionals understand the support that may be useful.
Support while waiting for assessment
A long wait can leave families feeling that everything is on hold, but practical support can begin before assessment.
Agree a small number of school adjustments and review whether they help. Ask the SENCO to record the child’s needs, the strategies being used and the progress observed. Keeping this information organised may also support the later assessment.
At home, focus on the situations causing the greatest difficulty rather than attempting to change every routine at once. Morning preparation, homework and bedtime are common starting points.
A simple record can help identify patterns. Note what happened, what came before it, how long the difficulty lasted and what helped. Avoid documenting only problems; record successful days and useful strategies too.
Sleep, regular meals and daily physical activity do not cure ADHD, but they can influence attention, mood and coping. Review these basics without blaming the child or presenting lifestyle changes as an alternative to appropriate assessment.
Some areas offer parent programmes, neurodevelopmental workshops or early-help support before diagnosis. Your school, local authority SEND information service, GP or assessment provider may be able to explain what is available.
Children who struggle with focus may also benefit from the practical suggestions in When Your Child Struggles to Focus.
Treatment and longer-term support
Support for ADHD is individual. It may include changes at school, information for the family, help with routines and emotional regulation, or medication prescribed and monitored by an appropriate specialist.
Educational support might involve clearer instructions, reduced distractions, planned movement, help with organisation and adjustments to longer tasks. The most suitable strategies depend on the child rather than the diagnosis alone.
Parents and carers may be offered ADHD-focused information, support or training. This is not because parenting causes ADHD. These programmes are intended to give families practical ways to support behaviour, communication and daily routines.
Older children may benefit from work on organisation, planning, emotional regulation and coping with impulsive decisions. Support may also be needed for anxiety, low self-esteem, learning difficulties or friendship problems.
Medication may be considered when symptoms continue to cause significant impairment. The decision should be made with an appropriately qualified specialist after discussing potential benefits, side effects and monitoring. Not every child with ADHD uses medication, and parents should not start, stop or alter prescribed treatment without professional advice.
NICE provides detailed recommendations about assessment, non-medication support and medicines in its ADHD diagnosis and management guideline.
SEN support, reasonable adjustments and EHCPs
A child does not need an ADHD diagnosis before a school can respond to identified special educational needs. If a pupil requires educational provision that is additional to or different from what is normally available, the school should discuss appropriate SEN support with the family.
This may involve an assess-plan-do-review cycle in which needs are identified, support is introduced and its effect is reviewed. Parents should be informed about special educational provision being made for their child.
Some children with ADHD may also meet the Equality Act definition of disability where the condition has a substantial and long-term negative effect on normal daily activities. In those circumstances, the school has duties relating to discrimination and reasonable adjustments.
Reasonable adjustments depend on the individual child and could include changes to instructions, routines, seating, movement opportunities or behaviour procedures. A diagnosis does not produce one standard list of adjustments.
When needs are significant and cannot be met adequately through ordinary SEN support, families or schools may consider requesting an Education, Health and Care needs assessment in England. An ADHD diagnosis alone does not automatically lead to an EHCP; the decision is based on the child’s educational needs and the provision required.
The government’s SEND Code of Practice explains the statutory system in England. Families can also read our guides to the difference between SEN support and an EHCP and SEN support and EHCPs for parents.
Frequently asked questions
At what age can ADHD signs appear?
ADHD traits begin during childhood, but the age at which they become noticeable varies. Difficulties may become clearer when a child starts school or moves to secondary education because expectations for attention, organisation and independence increase.
Does being energetic mean that a child has ADHD?
No. High energy is common in children. ADHD involves a persistent pattern of difficulties that is greater than expected for the child’s developmental stage and causes significant problems in important areas of life.
Can a child have ADHD without being hyperactive?
Yes. Some children mainly experience difficulties with attention, organisation and forgetfulness. They may appear quiet or dreamy rather than physically hyperactive, which can make their needs easier to overlook.
Can a school diagnose ADHD?
No. Teachers and SENCOs can identify concerns, gather evidence and support a referral, but an ADHD diagnosis must be made by an appropriately qualified healthcare professional with relevant training and expertise.
Should I speak to the school or GP first?
It is often useful to speak to both. The school can describe what happens in the classroom and introduce support, while a GP can consider health factors and explain the local referral route. In some areas, referrals are initiated directly by schools or other professionals.
Does my child need a diagnosis to receive support at school?
No. Schools should respond to identified educational needs and can introduce support or adjustments before a diagnosis. The type of provision should depend on the child’s actual difficulties and the effect on learning.
How long does an ADHD assessment take?
The assessment itself usually involves several sources of information rather than one short test. The overall process varies between services, and waiting times can differ considerably by area. Ask the local provider what stages are involved and what support is available while waiting.
Can ADHD be confused with anxiety or autism?
Yes. Anxiety, autism, sleep difficulties, learning needs and other circumstances can resemble or occur alongside ADHD. A full assessment considers alternative and coexisting explanations rather than relying on one symptom checklist.
Is ADHD caused by poor parenting or too much screen time?
No. ADHD is a neurodevelopmental condition and is not caused by poor parenting. Screen habits, sleep and family routines may influence how difficulties appear or are managed, but they do not provide a simple explanation for ADHD.
Where can UK families find reliable ADHD information?
Reliable starting points include the NHS guidance on ADHD in children and young people, NICE guideline NG87, YoungMinds, the Royal College of Psychiatrists and ADHD UK.
