What Happens at a Child ADHD Assessment in Ireland?

A child ADHD assessment in Ireland is a structured clinical process, not a single test. It typically involves a parent interview, questionnaires completed by parents and teachers, a child assessment session with a clinician, and a feedback appointment where results are explained. The full process usually takes between 3 and 6 weeks from first appointment to final report.

If you’ve already decided to have your child assessed, the next worry is usually about what they’ll actually have to do. This guide walks you through exactly what happens at each stage – warmly and without jargon – so you can arrive informed and confident, and so your child knows what to expect too. For the wider context of ADHD in children and teenagers, see our companion guide.

1. What Is a Child ADHD Assessment?

A child ADHD assessment is a multi-session clinical evaluation that gathers information about your child from several sources – you as the parent, your child’s teacher, your child themselves, and standardised rating scales. A qualified clinician then reviews all of that information together to reach a diagnostic decision.

It’s important to know what the assessment is not:

• There is no blood test for ADHD
• There is no brain scan
• There is no single pass-or-fail test
• Your child cannot “fail” an assessment

ADHD is diagnosed through clinical observation, structured interviews, and standardised rating scales. The reason an assessment takes multiple sessions across several weeks is that the diagnostic criteria require symptoms to be observed in more than one setting – typically home and school – and the clinician needs time to gather and compare that evidence.

2. Before the Assessment – What Happens First?

Before the full assessment begins, you’ll have an initial consultation to confirm that a full ADHD assessment is the right pathway for your child.

At ADHD Now, the initial consultation is a 45-minute video call with a specialist clinician, available within 7 days of booking. It costs €89 and does not require a GP referral. Either a parent or guardian attends. Your child may or may not be present at this stage – it depends on their age and how comfortable you think they’ll be.

The purpose of the consultation is to:

• Review your child’s history and current difficulties
• Confirm whether a full ADHD assessment is the correct next step
• Explain what the full assessment involves, what it will cost, and how long it will take
• Flag if a different specialist (for example, a speech and language therapist) might be more appropriate

What to prepare:

• Recent school reports
• Any previous assessments (speech and language, occupational therapy, educational psychology)
• A short list of specific behaviours that concern you at home and at school

After the consultation, pre-assessment questionnaires are sent to both parents and teachers so the clinician has structured data before the formal sessions begin.

3. Step 1 – The Parent Interview

The first formal step of the assessment is an in-depth parent interview, typically 45 to 90 minutes long. It’s conducted online via secure video call so you can speak freely from home.

This is where the clinician asks about your child’s full developmental history – prenatal period, birth, early milestones, when you first noticed something was different, school performance, and behaviour patterns at home.

You’ll be asked about:

• Early social interactions, play, and language
• Sleep, feeding, and sensory differences from infancy onwards
• The first behaviours that prompted concern, and at what age
• School performance and how your child manages transitions
• Family history of ADHD, learning differences, or mental health conditions

Why history before age 12 matters

The DSM-5 diagnostic criteria require symptoms to have been present in childhood, before age 12. Even if your child is only being assessed now, the clinician must build a picture that stretches back to early childhood to make a valid diagnosis.

If another parent, a grandparent, or someone else who knows your child well wants to contribute their observations, that’s often helpful – especially for families where both parents aren’t available for the full interview.

4. Step 2 – Your Child’s Assessment Session

This is the part most parents worry about most – what will my child actually have to do, and will they be upset?

At ADHD Now, the child assessment session is conducted online, which means your child can take part from home in a familiar environment rather than a clinical room. The session is designed to feel like a warm, age-appropriate conversation, not a test.

What your child will experience:

The clinician talks with your child about everyday things – what they enjoy, what they find difficult, who their friends are, how school is going, and how they feel day to day. For younger children, the clinician may use drawings, games, or play-based prompts to encourage them to open up. For older children and teens, it’s more of a conversation.

What the clinician is observing:

Throughout the session, the clinician is watching (warmly and unobtrusively) for things like focus, impulsivity, the ability to follow a conversation, emotional presentation, and how your child handles small transitions. These observations become part of the overall picture, alongside the rating scales and parent and teacher input.

Standardised rating scales:

For younger children, the rating scales are almost always completed by parents and teachers – not by the child themselves. Older children and teenagers may fill in a self-report version.

How online sessions work:

Your child sits at a quiet desk or table at home with the device. A parent is usually nearby at the start and end of the session. For part of the session, the clinician may speak with your child alone so they can answer honestly without feeling watched. You don’t need to prep your child with any “right answers” – the most useful session is an honest one.

Your child does not need to attend every session – just this one. The parent interview and the teacher questionnaire happen without them.

5. Step 3 – The Teacher Questionnaire

Input from your child’s school is essential for a valid ADHD diagnosis. It’s not optional.

The DSM-5 requires symptoms to be present in more than one setting to meet the diagnostic criteria – home and school are the two settings we look at for children. Your child’s teacher sees things you don’t, like how they cope during transitions, handle independent work, and interact with peers in unstructured time.

What teachers complete:

Standardised behavioural rating forms that quantify specific classroom behaviours (for example, difficulty sustaining attention on independent tasks, difficulty waiting turn, frequent fidgeting). These forms are sent to the school by email and returned the same way.

Parent tip: Let your child’s teacher know in advance that an ADHD assessment is underway and that a questionnaire will arrive. Teachers who are expecting the request typically complete and return them faster.

If a teacher is slow to respond, you can help by following up politely – or ask the school office to route the form to the Special Education Teacher, who often fills these out faster than a class teacher balancing 30 children’s workload.

6. What Diagnostic Tools Are Used?

There’s no single test that confirms ADHD. The assessment uses a combination of validated tools that, taken together, give a clear clinical picture.

DSM-5 criteria – the diagnostic manual your clinician uses to check which symptoms are present, how frequent they are, and how much they interfere with your child’s daily life.

Conners Rating Scales – standardised behavioural questionnaires completed by parents and by teachers. They measure the frequency and severity of specific behaviours and compare your child to a large normative sample of peers.

DIVA-5 (or equivalent structured interview tool) – a semi-structured clinical interview that walks through each DSM-5 criterion one at a time, grounded in real-world examples from your child’s life.

What is not used:

• No brain scan
• No blood test
• No QB test as a substitute for clinical assessment

Multidisciplinary team (MDT) approach: ADHD Now uses two or more clinicians for every child assessment. This is considered best practice – it means the final diagnostic decision is never made by a single person in isolation.

7. How Long Does a Child ADHD Assessment Take?

The overall timeline from first appointment to final report is typically 3 to 6 weeks.

Individual session lengths:

• Initial consultation: 45 minutes
• Parent interview: 45–90 minutes
• Child assessment session: varies by age (usually 30–60 minutes)
• Feedback session: 30–45 minutes

Why it takes a few weeks rather than a single day:

A valid diagnosis requires information from multiple sources at different times, and the rating scales need to be returned by both parents and teachers. The evidence has to be reviewed as a whole, not in a single rushed appointment.

What can affect the timeline:

• How quickly the teacher questionnaire is returned
• Whether you have existing reports to share (speech, OT, psychology)
• The clinical team’s review turnaround

If the teacher questionnaire is delayed, that’s usually the one thing that extends a timeline. Letting the school know in advance typically keeps you in the 3–4 week range.

8. The Feedback Session – How Are Results Explained?

Results are never sent cold through the post. You receive them in a dedicated feedback session with the clinician.

What the feedback session covers:

• The diagnostic decision and the reasoning behind it
• Your child’s specific profile – which symptoms are most prominent, which strengths stand out
• Tailored recommendations for home and for school
• Next steps if therapy, coaching, or medication are being considered

If ADHD is confirmed, you’ll leave the session with a clear understanding of your child’s specific presentation and a realistic plan for supports. A diagnosis is an explanation, not a label – it describes how your child’s brain works and helps you advocate for them.

If ADHD is not confirmed, you still receive a full explanation of what was observed. The clinician may identify other factors (anxiety, learning differences, sensory processing) that better explain your child’s experience, and will recommend the most appropriate specialist or intervention. No assessment time is wasted.

The written report is delivered within 10 days of assessment completion.

9. What Is in the Diagnostic Report?

The written report is the single most important document to come out of the process. It’s what your child’s school, the State Examinations Commission, the CAO, your GP, and future clinicians will all rely on.

What the report covers:

• Your child’s developmental history
• The methodology used and the instruments administered
• Findings from each source of evidence (you, the teacher, your child, the rating scales)
• The diagnostic decision
• A detailed profile of strengths alongside challenges
• Practical recommendations for home, school, and clinical next steps

How to use the report:

• Share it with your child’s school to support requests for SET hours, SNA allocation, or a Student Support Plan
• Use it for RACE (Reasonable Accommodations at Certificate Examinations) applications
• Use it for DARE (Disability Access Route to Education) applications at third level
• Provide a copy to your GP for continuity of care
• Keep a copy for the workplace if your child is a teenager moving into employment

Who accepts ADHD Now reports: the HSE, every Irish school, Irish universities, GPs, and the State Examinations Commission.

10. What Happens After a Diagnosis?

A diagnosis is the start of a more supported life, not the end of the journey.

Clinical next steps at ADHD Now:

• ADHD therapy and coaching to build organisation and emotional regulation skills
• Child psychiatry and child ADHD medication Ireland, which is a separate clinical service following assessment

Sharing the report with your child’s school:

The school can use the report to build a Student Support Plan or Individual Education Plan, request Special Education Teaching (SET) hours, and apply for SNA support where significant care needs are involved. See our guide to ADHD support in Irish schools for the full breakdown.

RACE – exam accommodations for Junior and Leaving Cert:

Schools apply for RACE on your child’s behalf, typically in the autumn of the examination year. Accommodations may include additional time, a word processor, a spelling and grammar waiver, a separate centre, or supervised rest breaks. The 2026 exam cycle introduces an interim measure giving eligible candidates an additional 10 minutes per written paper.

DARE – reduced CAO points for third level:

DARE requires a formal report from a consultant psychiatrist or chartered psychologist that is less than 3 years old at the time of CAO application. If your child is in secondary school, plan an updated assessment early in Fifth Year to protect DARE eligibility.

11. CAMHS and Private – How the Two Routes Compare

Many families arrive at a private assessment after a long wait on a CAMHS list, and both routes are valid pathways to a clinical answer. The key difference is timing – and timing is something that quietly matters more than parents often realise.

A 2-3 year wait for an HSE appointment is not just an administrative inconvenience. During those years, a child whose behaviour or school performance is misunderstood may begin to internalise the difficulty as a personal failing. Being repeatedly told off at school, falling behind academically, or feeling “different” without a name for it can take a real toll on a young person’s emotional wellbeing and self-esteem. A timely assessment – whether public or private – allows the right supports to be put in place at home and at school, so a child can grow into their social, emotional and academic potential rather than be defined by the gap.

CAMHS route:

• GP referral required
• Free at the point of delivery, with multi-stage assessment by a HSE community team
• Currently a 2-3+ year wait in most CHO areas before an appointment

ADHD Now private route:

• No GP referral needed
• Initial consultation within 7 days
• Full assessment completed within 3–6 weeks
• Online nationwide – available anywhere in Ireland
• Involves a cost, offset by 20% Med 1 tax relief

What’s the same across both routes:

• Both use validated diagnostic tools (DSM-5, Conners, DIVA-5)
• Both reports are fully accepted by Irish schools, the State Examinations Commission, and the CAO
• Both meet the clinical standards required for medication management
