Quality, Compassion, and Care
At GSP assessments, we provide ADHD and Autism assessments across Europe. Our multi-disciplinary and neuro-affirming approach aims to provide a comfortable experience. Compassion underpins everything we do, and our mission is to give you the confidence to thrive. Rather than viewing neurodiversity through a deficit-based lens, we aim to define your unique neurodevelopmental profile, recognising both strengths and areas where additional understanding or support may be beneficial.

Who We Support
GSP Assessments welcomes people of all ages seeking clarity around Autism and ADHD. From young children showing early signs of difference, to adolescents navigating school and social pressures, through to adults who may have gone undiagnosed for years, we provide assessments tailored to each life stage. We understand that neurodivergence presents differently across a lifetime, and our approach reflects this, including:
• Early assessments for young children
• Support for adolescents balancing school, friendships and identity
• Diagnosis for adults, including late-identified Autism and ADHD
• Consideration of co-occurring conditions and individual circumstances
• A welcoming, non-judgemental space for the whole family
• Guidance suited to each person's stage of life and needs
Why Choose Gold Standard Psychological Assessments?
At Gold Standard Psychological Assessments, we believe that everyone deserves an assessment that truly sees them — not just their symptoms, but the full picture of who they are. Here's what sets us apart.
Every Assessment Follows International Gold Standards
Our assessments are built on the most rigorous, internationally recognised frameworks and diagnostic criteria available. We don't cut corners or rely on outdated tools — every evaluation we carry out reflects the latest evidence-based research and best clinical practice, so you can trust that your results are accurate, thorough, and meaningful.
A Psychiatrist Is Involved in Every Assessment
Unlike many providers, we include a consultant psychiatrist as part of every single assessment we conduct. This isn't a box-ticking exercise — it's a clinical commitment. Having a psychiatrist involved ensures that complex presentations are considered from a medical perspective, that differential diagnoses are properly explored, and that any recommendations made are clinically sound and actionable.
Specialist-Trained in High-Masking Neurodiversity
We understand that many people — particularly women, girls, and those who have spent years adapting to fit in — present in ways that standard assessments can miss entirely. Our clinicians receive specialist training in identifying high-masking presentations of autism, ADHD, and other neurodivergent profiles. We know how to look beyond the surface, ask the right questions, and create a space where your true experience can come through — often for the very first time.
More Than a Report
We know that receiving a diagnosis, or understanding why one doesn't fit, can be life-changing. That's why our process is built around you — not just your scores. You'll receive clear, jargon-free feedback, time to ask questions, and recommendations that are genuinely useful in your daily life, whether for work, education, healthcare, or simply understanding yourself better.
