Expert Child ADHD Assessments You Can Trust

Our child ADHD assessments are available online across the UK or in person at our Kent and Cheltenham clinics, adhering to NHS and NICE guidelines. Our experts are experienced in recognising how ADHD presents across different ages and developmental stages, ensuring assessments are sensitive, thorough, and supportive. Combining specialist knowledge, evidence-based tools, and a compassionate approach, we provide clear, comprehensive assessments that help families understand and support their child’s unique needs.

Common Signs of ADHD in Children

ADHD presents differently in every individual. While many children with ADHD share common traits, these experiences vary widely and are often shaped by gender, environment and life stage. Recognising these patterns can help people better understand themselves and access the right support.

What Happens in a Child ADHD Assessment?

1

Before Your Child’s Diagnostic Interview

To ensure we’re the right service for your child, we’ll begin with a brief triage process. You (parent/guardian), your child’s school and your child (where appropriate) will be asked to complete a series of questionnaires about them. This will help us to build a comprehensive understanding of experiences and behaviours.
2

Your Child’s Diagnostic Interview

Your child’s assessment takes place via secure video consultation with an experienced clinician and lasts up to 2 hours. Both you (parent/guardian) and your child will be required to attend. The in-depth clinical assessment will gather detailed information on developmental history, asking questions like “when did your child learn to walk, or read”. There will also be information gathered about symptoms and family life.
3

Your Child’s Outcome & Report

In most cases, you’ll receive your child’s diagnostic outcome during the appointment. Where further review is needed, the case will be discussed by our multidisciplinary team to ensure clinical accuracy and confidence in the diagnosis. Your child’s detailed clinical report will be provided within 10 working days and, with your consent, shared with your GP.

Child ADHD Assessment FAQs

Who are child ADHD assessments for?
Our ADHD assessments are designed for children aged six and above who may show signs such as difficulty focusing, impulsivity, hyperactivity, or challenges with organisation and emotional regulation. Assessments help families gain clarity, understanding, and a plan for appropriate support.
Are appointments available online or in person?
Our private assessments can take place online or in person at our Kent and Cheltenham clinics, giving families flexibility and choice.
What happens during a child’s ADHD assessment?
Assessments are carried out by experienced Neurodevelopmental Assessors using evidence-based tools such as the DIVA or other recognised diagnostic interviews, alongside input from parents, teachers, and caregivers. The process is child-centred and supportive, aiming to build a clear picture of your child’s strengths, challenges, and needs.

Each report is then clinically reviewed and signed off by a Psychiatrist, ensuring diagnostic accuracy and clinical oversight. Following this, a diagnostic outcome meeting is held with a qualified therapist (Psychiatrist, Pharmacist, or GP) to discuss the results, confirm the diagnosis, and outline next steps for support.
How do you account for differences in how ADHD presents in boys and girls?
Our team receives ongoing training in recognising how ADHD can look different across genders, ages, and cultural backgrounds. Girls with ADHD, for example, may show more inattentive traits, masking behaviours, or emotional sensitivity rather than overt hyperactivity. RTN’s approach ensures these differences are recognised so that every child is assessed fairly and accurately.
How soon can my child start their assessment?
Once you book a private assessment, your child’s process can begin within 24 hours. We don’t commit to fixed completion timeframes, as progress depends on completing pre-assessment forms and appointments.
What does “adheres to NICE guidelines” mean?
It means our team follows the standards recommended by the National Institute for Health and Care Excellence (NICE) for diagnosing ADHD in children. This ensures every assessment meets nationally recognised standards of safety and quality.
What support is available after diagnosis?
You’ll receive a detailed report outlining recommendations for next steps, including strategies for home and school.
Can I pay for my child’s assessment in installments?
Yes. Flexible payment options are available, allowing you to spread the cost of your child’s assessment.
