In a startling revelation, new research has exposed significant disparities in the rates of positive autism assessments across different parts of England. The study, conducted by the charity Autistica, raises profound questions about the consistency and fairness of the diagnostic process for individuals on the autism spectrum.
Autism Diagnosis: A Postcode Lottery?
The data, obtained through Freedom of Information requests, paints a concerning picture. In some NHS foundation trusts, nearly all children evaluated for autism received a positive diagnosis, while in others, less than one in five met the diagnostic criteria. The figures for adults were equally variable, ranging from a 97% positive assessment rate to a mere 14%.
What our robust research – the first of its kind – shows is that each integrated care board is taking a different approach to autism diagnoses.

Investigating the Inconsistencies
These findings raise alarm bells about the lack of standardization in autism assessments across the nation. Dr Steve Bush from the Cambridgeshire trust pointed to variations in how services are commissioned and the differing needs of referred children as potential factors behind the inconsistencies.
However, experts warn that the extreme variability could also stem from idiosyncratic interpretations of autism among clinicians and uneven adherence to diagnostic criteria. This postcode lottery of autism diagnosis has far-reaching implications for individuals and families seeking support.
The Human Cost of Diagnostic Disparity
Behind these statistics lie real people – children and adults grappling with the challenges of autism, often without the validation and support that a timely diagnosis can provide. The inconsistencies in assessment rates across England mean that access to vital services and interventions can hinge on geographic location rather than individual needs.
This extreme variability is unacceptable and evidence the system isn’t working. That is because nowhere has the resources to follow the NHS framework.

The National Autistic Society underscores the urgent need for a more robust, equitable diagnostic system. With referrals for autism assessments surging by 140% over the past four years, the pressure on underfunded services is immense.
Charting a Path Forward
In response to these findings, the NHS has issued new national guidance aimed at helping local partners deliver high-quality, consistent autism assessment services. Enhanced training for psychiatrists is also on the cards, reflecting a commitment to tackling the postcode lottery head-on.
However, guidance alone may not suffice. Experts are calling for rigorous monitoring of diagnostic practices, greater investment in autism services, and a concerted effort to standardize assessment criteria across the country.
A Wake-Up Call for Change
The stark variations in autism diagnosis rates exposed by this research serve as a powerful wake-up call. They underscore the urgent need for a more equitable, standardized approach to autism assessments – one that places the needs of individuals and families at its heart.
As we move forward, it is imperative that policymakers, healthcare providers, and autism charities work together to ensure that every person on the autism spectrum, regardless of their postcode, has access to timely, accurate diagnosis and the support they need to thrive. Only then can we begin to dismantle the diagnostic divide and build a society that truly embraces neurodiversity.
The path ahead may be challenging, but the stakes could not be higher. By confronting the inconsistencies in autism diagnosis head-on, we have an opportunity to transform lives and create a more inclusive, understanding world for all.
