We are delighted to announce the publication of the Independent Schools’ Inspectorate Report on St Mary’s School Ascot for 2025. 

The ISI’s inspection of the school took place in January 2025, as part of their routine programme of school inspections. The last inspection took place in 2021, in which St Mary’s was rated ‘Excellent’.  

Since the last Inspection, the ratings system used by the ISI has changed, so the previous system of single word judgements no longer applies. Instead, the ISI now produce a description of their findings. 

In rare circumstances, the ISI may recognise that a school has a ‘significant strength’. This accolade has not been awarded lightly by inspectors under the new framework, so we are extremely pleased that the inspectors did find that St Mary’s had a significant strength, in our development of the pupils’ social understanding. This is something of which we feel Mary Ward would have been very proud.  

Part of the inspection also looks at compliance with regulatory standards. In respect of these, the ISI’s only judgement is whether the standards have been met. We are pleased to announce that St Mary’s did meet all the regulatory standards.
