ADHD ASSESSMENTS Kingston-upon-Thames
Specialist ADHD assessments in Kingston for children, adolescents, and adults
At Sage Psychology, we provide Gold-Standard ADHD assessments in Kingston-upon-Thames, supporting children, adolescents, and adults who are seeking clarity, understanding, and the right pathway forward. Our assessments are comprehensive, evidence-based, and delivered by highly experienced psychologists.
Receiving an ADHD diagnosis can be a pivotal moment. For many, it brings relief, validation, and a clearer understanding of lifelong challenges with focus, organisation, emotional regulation, or impulsivity. However, the quality of an ADHD assessment matters greatly. With increasing concerns around brief or unreliable diagnoses, it’s essential to choose a service that follows rigorous clinical standards.
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 your child, 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 yours or your child’s story, 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 Kingston, 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.
Evidence based tools
We use "Gold-Standard" validated questionnaires to ensure our findings are backed by data
NICE-guideline compliant
This is the "North Star" for UK healthcare, ensuring your report meets the standards of the NHS.
Multiple Perspectives
We don’t just rely on your memory; where possible, we collect information from other sources to see how you function in different environments.

We don’t just email you a report. We sit down with you to explain the "why" behind your results and help you plan your next steps as part of your roadmap.
