The ADHD Wise Diagnostic Service provides ADHD diagnostic assessment for adults, children and young people.
The service combines online pre-assessment information, Creyos Cognitive Assessment, age-relevant ADHD questionnaires, developmental and background history, and a structured ACE/ACE+ diagnostic interview.
The aim is to consider whether ADHD is an appropriate diagnosis, understand how ADHD traits may be affecting daily life, and provide a clear written report with practical recommendations.
ADHD diagnostic assessment with clear process, structured method and practical recommendations
Who the service is for
- Adults: 18+
- Children and young people: 6–17
For young people aged 17, we will contact you before confirming the pathway to ascertain whether the child/young person assessment or adult assessment is most appropriate.
Fees:
Adults (18+): £950
Children (6-17): £1,150
Age 17: See above
A £195 non-refundable booking fee is paid at the time of booking and deducted from the full assessment price.
Medication prescribing
If your main reason for assessment is to explore ADHD medication, please do not book this service. Adults should seek a psychiatrist or appropriately qualified ADHD medical prescriber. For under-18s, this would usually be a paediatrician or child psychiatrist.
Availability and Booking
If you would like to find out more about this service or book and assessment, please complete our contact form providing the name, address, email address and age of the person to be assessed. We will then send you an initial questionnaire to complete and a payment link for the non-refundable deposit.
THE PROCESS
You book a full ADHD diagnostic assessment appointment at least three weeks in advance.
At the time of booking, you pay a £195 non-refundable booking confirmation fee. This confirms your appointment and is deducted from the full assessment price.
Step 2: Complete the online pre-assessment information
During the first week, you complete the online pre-assessment information.
This includes:
- Creyos Cognitive Assessment
- general health/background information
- age-relevant ADHD questionnaires
- developmental information, where relevant
- parent/carer information, where relevant
- school or education information, where relevant
We will prompt you through this process, and offer guidance if you need it. We understand the paradox of asking people who may have ADHD to complete important tasks ahead of time, so we have built support into the pathway.
Step 3: We review the pre-assessment information
After the pre-assessment information has been completed, we review it before the full assessment appointment.
In most cases, the assessment will go ahead as planned.
If there is reason to doubt that full ADHD diagnostic assessment is appropriate, we will contact you before the remaining balance is paid. This is expected to be rare, but it helps reduce the risk of you spending significant money on an assessment that may not be right for you or your child.
Step 4: Pay the remaining balance
After the pre-assessment information has been completed and reviewed, we send a payment link for the remaining balance.
The balance can be paid in one payment or in two parts.
The first balance payment must be paid before the assessment appointment.
Full payment must be received before the diagnostic report is released.
Step 5: Attend the diagnostic assessment appointment
The full diagnostic assessment appointment uses ACE/ACE+ clinical interview tools and explores ADHD traits, developmental history, current presentation, functional impact and support needs.
For children and young people, the assessment also considers information from parents/carers and, where available, school or education settings.
Step 6: Receive your diagnostic report
After the assessment, you receive a written diagnostic report.
The report includes the assessment findings, diagnostic outcome, formulation and recommendations.
Full payment must be received before the report is released.
The method draws together several sources of information, including:
- Creyos Cognitive Assessment
- age-relevant ADHD questionnaires
- general health and background information
- developmental history
- current presentation
- evidence of impact across daily life
- parent/carer information, where relevant
- school or education information, where relevant
- structured ACE/ACE+ diagnostic interview
- consideration of co-existing or alternative explanations
The assessment considers ADHD traits across the areas of attention, activity, impulsivity, executive functioning, emotional regulation, masking, compensatory strategies, strengths, barriers and functional impact.
The diagnostic decision is made by considering the whole picture: the person’s history, current experiences, questionnaire evidence, cognitive information, real-life examples, impact across settings and whether ADHD provides an appropriate explanation for the pattern of need.
What ACE/ACE+ means
ACE and ACE+ are structured clinical interview tools used to support ADHD diagnostic assessment.
They help guide the assessment conversation so that relevant areas are explored carefully and consistently. This includes ADHD traits, developmental history, examples from daily life, functional impact, and wider factors that may need to be considered.
In the ADHD Wise Diagnostic Service:
- ACE+ is used for adult assessment.
- ACE is used for child and young person assessment.
The tools support the diagnostic process, but the assessment also considers wider information, including questionnaires, cognitive assessment, health/background information and contextual evidence.
What the report can include
The written report may include:
- assessment method
- tools and information used
- relevant developmental/background history
- ADHD traits considered
- executive functioning profile
- emotional regulation
- masking and compensatory strategies
- functional impact
- strengths and support needs
- diagnostic outcome
- formulation
- recommendations for home, education, work or daily life
- signposting where appropriate
