ADHDASSESSMENTS Chessington
Trusted ADHD assessments for children, adolescents, and adults
Sage Psychology offers Gold-Standard ADHD assessments for adults and children in Chessington and the surrounding area. If you have been wondering whether ADHD might be behind long-standing challenges at school, at work, or in daily life, a thorough, professional assessment is the clearest route to answers.
ADHD is frequently misunderstood and, in many cases, goes unrecognised for years. Children written off as disruptive or inattentive, adults who have spent decades compensating for difficulties with focus, planning, or emotional regulation, people who have sensed something was different but never had a name for it. A high-quality assessment changes that. It provides not just a diagnosis, but a fuller picture of how a person thinks, processes, and experiences the world.
Why chOOSE our adhd assessmentS?
We understand that choosing where to go for an ADHD assessment is not a decision taken lightly. Our assessments are grounded in clinical rigour, and we take the time required to get it right. That means no rushed appointments, no checkbox approaches, and no conclusions drawn without proper clinical review.
What Makes a High-Quality ADHD Assessment?
Not all ADHD assessments are equal. If you are searching for an ADHD assessment, these are the standards worth asking about:
Assessments should be conducted by qualified, experienced mental health professionals
with specialist knowledge of ADHD in children, adolescents, and adults.
A thorough assessment combines structured diagnostic interviews
validated rating scales, and collateral information from parents, teachers, or partners where appropriate.
A multi-practitioner model,
where findings are reviewed by a second clinician before any diagnosis is confirmed, significantly strengthens reliability.
ADHD rarely exists in isolation.
A quality assessment will explore whether autism, depression, anxiety or other conditions are also present.
A full three-hour diagnostic interview
is needed to properly explore developmental history, current challenges, and real-world impact. Shorter assessments risk missing the full picture.
You should receive a detailed written report
and a dedicated feedback session, not just a letter confirming a diagnosis.
Clear guidance on post-diagnostic support,
including therapy and ADHD coaching, should be part of the process from the outset.
We are proud to say
