Thornton College was visited by the Independent Schools Inspectorate (ISI) for a full inspection from 23rd to 25th September 2025.
The ISI stopped issuing an overall grade/judgement from September 2023 onwards. The new framework focuses instead on the extent to which the statutory Independent School Standards and other applicable regulatory requirements are met. We are delighted to confirm that Thornton met every one of these standards.
