Finally, the Answers You've Been Looking For
Comprehensive, NICE-compliant autism assessments for adults — delivered with respect, clarity and expertise.
What we offer
Many autistic adults reach adulthood without ever having received a diagnosis — having spent years masking, struggling and wondering why they find certain things so much harder than everyone else seems to. A formal autism assessment as an adult can be transformative — providing long-sought answers, access to support and a new understanding of yourself. At Abacus Psychology Service, we provide comprehensive, NICE-guideline compliant autism assessments for adults using gold-standard diagnostic tools, with particular experience in late identification and masking.
Why an Adult Autism Assessment Matters
For many adults, a late autism diagnosis is not a label — it is a liberation. It explains why social situations have always felt exhausting, why sensory environments are overwhelming and why the world has sometimes felt bewildering when others seem to navigate it effortlessly. A diagnosis can open access to workplace adjustments, appropriate support services and a community of people who share your experience. It can also inform more targeted, effective therapeutic support for anxiety, burnout and depression.
Our Adult Autism Assessment

We conduct a detailed clinical interview exploring your developmental history, current experiences, social communication, sensory experiences and the impact of your difficulties across different areas of life.
Gold-Standard Assessment Tools
We use standardised tools including ADOS-2 — internationally recognised instruments that ensure our assessments are rigorous and credible.
Masking & Late Identification
Our assessors are experienced in recognising autism in adults who have spent years masking — including women, those from minority ethnic backgrounds and those who may not fit stereotypical presentations.
