ADHD assessments for children and teenagers

Get assessed in days, not months. Our clinicians provide clear, evidence-based ADHD assessments tailored to your child’s needs, so your family gets answers and support sooner.

Considering an ADHD assessment for your child?   

At Xyla, our clinician-led assessments are tailored for children and teenagers, giving you a dedicated point of contact and clear guidance every step of the way. A formal diagnosis can help you and your child with: 

Early support in life

Identifying ADHD early means timely strategies to help your child manage challenges before they affect learning, behaviour and confidence.

Better understanding

Parents, teachers and caregivers gain insight into how your child experiences the world, leading to more effective and compassionate support.

Access to school support

A diagnosis can open the door to tailored educational help, such as EHCPs, extra time in exams and classroom adjustments to help your child thrive.

Improved long-term outcomes

With the right strategies in place, children are better equipped to succeed academically, socially and emotionally.

Real stories. Real support.

Our 9-year-old daughter has suspected ADHD, and after waiting over a year on the NHS waiting list, we turned to Xyla in search of answers. We had previously gone through the NHS assessment process with our son – which, although ultimately helpful, was lengthy and conducted face-to-face. Because of that experience, I was initially slightly hesitant about the virtual format Xyla offered – I wasn’t sure it could match the depth and connection of an in-person assessment. But from the very first five minutes, all those doubts disappeared.

Not sure if your child needs an ADHD assessment?

It’s completely normal to feel unsure if your child needs an assessment or if it’s in their best interests. That’s why our expert clinicians are here to guide you. We’ll walk you through the signs and symptoms of ADHD, answer your questions and provide honest, professional advice tailored to your child’s unique situation. 

If we don’t believe your child is likely to receive a diagnosis, we won’t recommend moving forward with an assessment. Our goal is to support you in making the right decision, not to put your child through a process that isn’t needed. We’re here to help, every step of the way.

Frequently asked questions

How do I know if my child or teenager has ADHD?

Common signs may include:

  • Inattention (e.g. forgetfulness, easily distracted)
  • Hyperactivity (e.g. restlessness, excessive talking)
  • Impulsivity (e.g. interrupting, difficulty waiting their turn)
  • Emotional challenges (e.g. frustration, anger, or difficulty managing emotions)

If your child or teenager consistently shows several of these behaviours, an assessment can help identify their needs and guide the next steps.

Do I need a GP referral to get an ADHD assessment for my child?

No referral is required. However, involving your GP can be helpful, as they can provide valuable background information and assist with coordinating any follow-up care.

Is the diagnosis valid for educational support?

Yes. Schools are required to provide reasonable adjustments based on a formal diagnosis, including extra exam time or tailored teaching methods.

What happens after a diagnosis?

You’ll receive a detailed report with personalised recommendations. This might include:

  • Supportive therapy for your child to help them manage and thrive
  • Guidance for parents and/or legal guardians to help understand the diagnosis and navigate the next steps
  • Referrals to additional support services for further assistance
  • Advice on school accommodations to assist with learning
  • Information on medication (if appropriate)
Will I be able to access medication for my child?

After an ADHD diagnosis, we may recommend medication when appropriate. While we don’t currently prescribe medication, we’re working towards offering this soon. In the meantime, we provide post-diagnostic care plans and emotional and behavioural support tailored to children and teenagers.

As part of our comprehensive, ongoing care, we also offer guidance for families and schools to help support each child’s journey.

How long does a child ADHD assessment take?

Our remote clinical assessment for ADHD in children usually takes around 60 minutes, followed by a separate 30-minute feedback session. From your initial consultation to receiving your diagnosis, the full process can typically be completed within 14 days. Timeframes may vary slightly depending on your availability and individual needs.
