ADHD assessment • A guide for parents
What happens during an ADHD assessment?
A clearer picture of the stages involved, how your child takes part and what you can ask along the way.
An assessment brings together information about your child over time. Understanding the process can help you and your child feel more prepared.
Understanding the process
There is no single appointment format
Services may organise appointments differently. Ask your provider what their assessment includes and how each part will work.
The clinician considers your child’s development, everyday experiences and needs. Information from parents, the child and other settings helps build a fuller picture than one appointment alone.
Step by step
The main stages of an ADHD assessment
Some stages happen before the appointment, others during it or afterwards. They may overlap or take place across several sessions.
1. Background and development
You may discuss early development, health, family history and when concerns first arose. The clinician explores the effect on everyday life, alongside your child’s strengths.
Useful preparation: bring relevant reports and examples rather than trying to remember every detail on the day.
2. Information from school
Teachers or the SENCO may share observations, learning information and completed questionnaires. Support already in place provides important context.
Let the service know: if your child is home educated, out of school or school information is difficult to obtain.
3. Meeting your child
The clinician may speak with your child and observe how they engage. Activities and conversations depend on their age, communication needs and the service’s approach.
Ask beforehand: whether any part is individual, whether you can stay and how breaks will work.
4. Questionnaires and tools
Parents and teachers may complete rating scales. Some services also use structured tasks or computer-based tools where appropriate.
Keep in mind: questionnaires and observations contribute to assessment; they do not establish a diagnosis on their own.
5. Reviewing the evidence
A suitably qualified clinician with ADHD expertise considers the information against diagnostic criteria, including other possible explanations and additional needs.
Sometimes: further information or another appointment is needed before a conclusion can be reached.
6. Feedback and recommendations
The clinician explains the findings and discusses appropriate next steps. Ask about any uncertainty and recommendations for home, school or further care.
Check arrangements: when feedback and a written report will be available, and who can answer follow-up questions.
Helping your child feel prepared
Keep the explanation simple and reassuring
Ask the service what to expect, then explain it in a way that suits your child.
Explain the purpose
“We are meeting someone who wants to understand what is easy and what is tricky for you, so we can work out what might help.”
Make it more predictable
Ask who they will meet, where the appointment is and what may happen. Share information gradually if that works better for your child.
Discuss adjustments
Tell the service about communication or sensory needs. Ask about breaks, a quieter waiting space or bringing a familiar item.
A short checklist for parents
- Complete requested forms and check what to bring.
- Write down everyday examples and support already tried.
- Include your child’s views, interests and strengths.
- List the questions you most want answered.
- Tell the service about medication and follow its instructions; do not change prescribed treatment without clinical advice.
Making the outcome useful
What happens after the assessment?
If ADHD is identified
Ask what the diagnosis means for your child and which support options are appropriate. Clarify who will provide any further care and how recommendations can be shared with school.

Ask what explains the findings and whether further advice or assessment is needed. Your child’s difficulties and support needs still matter.

Questions about the appointment
How many appointments will there be?
This varies by service and your child’s needs. Ask about the expected number, length and format of appointments, and what happens if more information is needed.
Can I stay with my child?
Ask the provider beforehand. Some parts may involve you together and others may include individual conversations, depending on your child’s age and needs. Discuss concerns about separation in advance.
What if my child is nervous or cannot complete an activity?
Tell the clinician and ask about adjustments, breaks or another way to gather the information. Explain what your child finds difficult rather than encouraging them to push through distress.
What if my child seems settled during the appointment?
Share the wider everyday picture and explain any differences between settings. The clinician considers information over time rather than relying only on how your child appears in one session.
Will we receive a written report?
Check what is included with your provider, when the report is expected and how factual errors can be raised. Ask for a clear explanation of findings and recommendations.
Does assessment include medication?
Do not assume prescribing or ongoing monitoring is included. If medication is relevant, ask who can provide specialist care and how follow-up arrangements would work.
