What Ofsted said

From the inspection on 19 November 2024

Pupils are proud to attend Kesteven and Sleaford High School. They thrive in the extremely positive culture that the school has established. In classrooms, pupils engage eagerly with the high-quality learning opportunities that staff provide. Pupils work hard and take pride in their successes. Staff share the very highest expectations of pupils, including those with special educational needs and/or disabilities (SEND). Pupils achieve exceptionally well. This is demonstrated consistently in external examinations. Most pupils go on to take advantage of the superb sixth-form offer. Students in the sixth form are very well prepared to go on to aspirational destinations. The school's programme for personal development is especially well considered and complements the academic curriculum. The programme has been designed precisely to give pupils the knowledge and skills they need to flourish. Pupils are taught how to keep themselves safe and healthy. They know why equality and diversity matter and understand the fundamental British values. The sixth-form enrichment programme includes sessions about cooking and guidance on managing finances. Pupils, and students in the sixth form, take on leadership roles enthusiastically, such as house captains and subject prefects. They are proud to support their peers and the school community.
