It's normal to feel anxious about an ADHD assessment.

While it can be long and complex, it's a step towards understanding yourself better and accessing support that fits your needs.

The aim is to simply explore whether you or your child has ADHD, and what support might help make life easier to manage.

What does an ADHD assessment include?

The assessment process is usually split into three stages: a pre-assessment, a clinical interview, and the results.

During the pre-assessment, a clinician will gather information about your development, adult experiences, and how your symptoms affect daily life. This is a good opportunity to provide specific examples of your struggles from both childhood and adulthood. The clinician may also speak to someone who knew you well as a child, such as a parent, sibling, or teacher. Old school reports and childhood documents aren't required, but they can help build a clearer picture of your experiences.

You may also complete online, game-like tasks known as a Creyos Check, which measure your memory, concentration, and problem-solving. It's understandable to worry about this, but it isn't a test of intelligence. The goal is simply to map out your strengths and challenges so support can be tailored to you at home, work, or in daily life.

The clinical interview can sound intimidating, but really it's a detailed conversation about how you coped at school, at home, and with friendships, as well as how you manage work, time, finances, and relationships as an adult. We also screen for autism and other mental health conditions to make sure any recommendations are right for you.

Although the process can feel daunting, it isn't a test. You won't fail or pass, and you don't need perfect answers. ADHD looks different for everyone, and clinicians know that people often mask their symptoms or develop coping mechanisms. The important thing is to trust what you feel and answer as honestly as you can.

After the assessment, you'll receive a report with a diagnosis, if applicable, along with recommended support, such as therapy or medication. If you're unsure about the results, you're entitled to ask for clarification or seek a second opinion.

Whatever the outcome, your struggles are real, and you deserve to feel heard and supported.
