What Ofsted said
From the inspection on 11 February 2025
St John's Marlborough is built on the ethos of 'Kind, Supported, Happy'. The school is ambitious for all pupils to achieve highly. The qualifications pupils and students in the sixth form achieve prepare them well for their next steps. The school has clear expectations for pupil behaviour. The new behaviour policy has been appreciated by staff and pupils because increasingly, it enables lessons to take place without disruption. The school does not tolerate bullying. It is proactive in providing avenues for pupils to raise concerns with adults. This means that pupils and staff have positive and mutually respectful relationships. Pupils take part in a range of extra-curricular activities to develop their talents and interests. Pupils are enthusiastic about performing in school productions and concerts. They are proud to represent their school in sporting competitions. Experiences such as visits to literary festivals and workshops about artificial intelligence bring the curriculum to life for pupils. The school has recently launched a new house system and a student forum. These are giving pupils the opportunity to take on further leadership roles. Pupils are excited about the chance to help to shape the future of the school.
What the school should improve
- Assessment within the classroom sometimes does not help adults accurately identify pupils' starting points or gaps in their knowledge and understanding. This means that some pupils do not receive the support or challenge they need to learn as well as they should. The school and trust should make sure that assessment routines check for un- derstanding and that the curriculum is adapted accordingly in response.
- The changes the school has implemented to improve the quality of provision are recent. They need further embedding to have the full positive impact on pupils that the school. The school and trust should ensure that the ongoing plans are implemented and reviewed to provide leaders and those responsible for governance with assurances that they are having the desired positive impact.
