Inspection Reports

The Independent Schools Inspectorate (ISI) completed a full inspection of Pennthorpe in November 2025.

A note from Mr Jon Marler, Head of School:

The ISI Inspection Framework no longer includes any gradings (e.g. ‘Good’ or ‘Outstanding’) but instead assesses whether a school ‘meets’ each of the following standards and then reports on them separately. These standards are:

• Leadership, Management and Governance
• Quality of Education, Training and Recreation
• Pupils’ Physical and Mental Health and Emotional Wellbeing
• Pupils’ Social and Economic Education and Contribution to Society
• Safeguarding

The inspection confirmed that Pennthorpe meets all Independent School Standards. This is a significant endorsement of our school, and one that reflects the care, commitment and expertise that runs through the entire Pennthorpe community.

“The school’s use of the ‘Pennthorpe Purpose’ develops pupils’ understanding of themselves as learners, encouraging independent learning and demonstrating diligence in all areas of their education.” Independent Schools Inspectorate (ISI), November 2025
