At a glance
Kesteven and Sleaford High School Selective Academy is a selective girls' grammar in Sleaford for Years 7 to 11, with post-16 study delivered through the co-educational Sleaford Joint Sixth Form. It sits within the Community Inclusive Trust, and its public values are concise and memorable: honesty and integrity, aspiration, professionalism and inclusivity. The school has around 756 pupils on roll.
The school describes its purpose as educating today's students for tomorrow's society. Below sixth form, the selective academy identity is clear: KSHS admits girls in the top 25% of the ability range and runs a grammar-school curriculum through to GCSE. At sixth form, the collaboration with Carre's Grammar School and St George's Academy widens the offer, with most students taking three Level 3 courses and some taking four; the Extended Project Qualification is also available.
The enrichment offer has a particularly practical shape in the sixth form. Wednesday afternoons are kept free for Academic, Altruistic and Active enrichment: examples include EPQ, debate, book club and subject clubs, volunteering, prefect roles, charity fundraising, Interact Club, music, cookery, sport and gym activities. Duke of Edinburgh is offered at Bronze, Silver and Gold, and curriculum pages such as Drama make explicit the school's interest in confidence, communication, cooperation and creativity.
Year 7 admission has 124 places. For 2027 entry, the Lincolnshire route uses two GL-style papers: verbal reasoning and non-verbal reasoning, sat on separate Saturdays, with children needing to reach the agreed minimum standard before oversubscription criteria are applied. Those criteria include looked-after status, pupil premium or recent free-school-meals eligibility, siblings, children of staff and distance. Ofsted judged the school Good in November 2017, with Outstanding subjudgements across the inspected areas; GOV.UK shows +0.67 Progress 8, 95.6% grade 5+ in English and maths, and 20.3% AAB or better at A level.

Places are allocated to qualified children in a fixed oversubscription order: looked-after children, pupil-premium eligibility, trust siblings, then straight-line distance. The qualifying standard is set through the Lincolnshire GL selection tests rather than a fixed school-specific score in this record.
There is no catchment boundary. After earlier priority groups, straight-line distance from the permanent home address ranks the remaining qualified applications.
Looked-after, previously looked-after, and internationally adopted previously looked-after children
Qualified children in care, previously looked after, or previously looked after outside England are first in the oversubscription order.
Pupil premium or free school meals in the previous six years
Qualified children eligible for pupil premium or who have received free school meals in the previous six years are next.
Siblings at a Community Inclusive Trust secondary school
Qualified children with a sibling already attending one of the trust's secondary schools follow next.
Straight-line distance from home to the academy
Remaining qualified children are ranked by straight-line distance from their permanent home address to the academy, nearest first.
Independent lottery for tied distances
If distance is identical for the final place, the academy uses a lottery supervised by an independent person.
For 2027 entry there are two GL-style papers: verbal reasoning on 12 September 2026 and non-verbal reasoning on 19 September 2026.
