ADHD ASSESSMENT

Understanding the ADHD assessment process in the UK

If you suspect you or your child may have ADHD, considering a referral for assessment can feel like a daunting journey, but knowing the steps can make it feel more manageable. 

In the UK the two main routes to assessment, NHS and private, are likely to differ depending on your location.

1. The NHS Route

Adults:

Start by speaking to your GP.  They may ask you to fill out questionnaires and describe your concerns.  If they agree that an assessment is appropriate, they will refer you to a specialist service - usually a psychiatrist.  Due to high demand, NHS waiting times can be long, sometimes over a year.    If there is no adult ADHD service in your location, you may be able to use your Right To Choose (which is only available in England, not Scotland, Wales or Northern Ireland and is only available for adults).

Children:

Start by speaking to your GP. They may ask you to fill out questionnaires and describe your concerns.  The pathway for some NHS trusts is that referrals must be made by the school.  According to NICE guidelines, symptoms of ADHD should be evident before the age of 12 and present for at least six months in two or more settings (e.g. school, home, other social situations).  However, most NHS referral pathways require that ADHD symptoms are present within school.

2. The Private Route

You can also choose to pay for a private assessment, which often means a shorter wait. Make sure the clinician or company are following NICE guidelines and are registered with an appropriate regulatory body. 

A good private report will include a detailed history, input from family or school, and clear diagnostic reasoning. 

 

Some GPs may accept a private diagnosis to prescribe ADHD medication under a Shared Care Agreement, but this is not guaranteed. 

We recommend that you check this with your GP before committing to this pathway.

What Happens During the Assessment?

Whether NHS or private, a typical ADHD assessment may include:

  • A detailed developmental and medical history

  • Questionnaires about behaviour and functioning

  • Reports from school 

  • Input from individuals who can provide information about the behaviour and functioning of the individual in everyday settings

  • A structured interview or observation

  • Consideration of other possible conditions

Diagnosis or Not - It’s Still Progress

If ADHD is diagnosed, the next steps may include education, behavioural strategies, coaching and/or medication. 

 

If not, your assessment may highlight other important areas to explore. 

 

Either way, it is a step toward better understanding of yourself and support.
