ADHD ASSESSMENTS Leatherhead
Specialist ADHD assessments for children, adolescents, and adults
Sage Psychology offers Gold-Standard ADHD assessments for adults and children from Leatherhead and the surrounding area. Whether you are seeking answers for a child who has been struggling to keep up at school, a teenager whose difficulties span multiple areas of life, or yourself as an adult who has never had a satisfactory explanation for long-standing challenges, our assessment process is designed to provide clarity you can rely on.
Getting to the point of seeking an ADHD assessment often takes longer than it should. For children, concerns can be dismissed as behavioural. For adults, years of managing difficulties alone can make it hard to know whether what they are experiencing is ADHD or simply the demands of a busy life. A thorough, evidence-based assessment resolves that uncertainty, providing a clear picture of what is happening and a foundation for the right support.
How does it work?
Keeping assessments simple and accessible
We know how overwhelming it is to look for an ADHD assessment. We have designed our process to be as clear and supportive as possible, so you can follow one simple step at a time.
Step 1
Book a Discovery Call
This is a 20 minute chat via Zoom with Dianne Everitt to look at your history and current challenges. We’ll determine if an ADHD assessment is the right path for you, or if another direction would serve you better. If you have been referred by another professional, you can skip this step.
Step 2
The comprehensive assessment
Once we’ve confirmed the pathway, we’ll guide you through the initial paperwork and then meet for a 3 hour clinical interview. This is a deep-dive into your story, your struggles, and your unique strengths. The appointment can be in person or online.
Step 3
Your results and roadmap
Three to four weeks after your assessment, we’ll meet for a feedback session. You’ll receive a comprehensive report that is NICE-compliant and widely accepted. Our reports provide more than a diagnosis. We give you a tailored roadmap with clear steps to take.
What Makes a High-Quality ADHD Assessment?
When looking for trusted ADHD assessments in Leatherhead, it’s important to consider the following key elements:
The expertise rule
With over 10 years of experience, you are seen as an expert, rather than a generalist.
a 3-hour deep dive
Anything less than this is not enough to reach a thorough, evidence based diagnosis.
A Holistic View
We look beyond ADHD to see the whole picture of your mental health, exploring possible co-occurring conditions such as anxiety, depression, or autism.
A team approach
Although a team approach is not required for ADHD assessments, we like to have regular peer reviews within our team, to increase the rigor of our results.
