UK Education AI Readability 2026
As of 1 October 2026, the median UK education site scored 48 out of 100 on the Crane Index™, the measure of how readably a site presents itself to AI engines. Across the 91 sites a machine could read, scores ran from 23 to 78, a 55-point gap between the strongest and the weakest.
What this measures. The score reads how readably a site presents itself to AI engines: entity markup, structured data and machine resolvability. It is not a measure of design, brand or quality. A site can look excellent to a person and still be hard for a machine to read, and a low score is a readability finding, never a judgement on the business.
The field in 2026
The field was led by Fettes College at 78, with Dukes Education next at 74. 5 sites cleared 70 out of 100, and 18 scored below 40.
At the foot of the field sat King's College School, Wimbledon at 23, Inspired Education at 33, Greenshaw Learning Trust at 34. Each is a site a machine struggled to read, not a business doing anything other than well at what it does.
The full 2026 ranking
Composite out of 100, with the three reads behind it: AI Search Readiness (retrieval), Agent Readiness (execution) and Brand Representation.
