Caistor Grammar School is a compact co-educational grammar school in the Lincolnshire market town of Caistor, serving pupils from 11 to 18 with about 669 on roll. Its official mission is unusually direct: lively minds, hard work, developing talents, and growing through sharing. That gives the school a tone closer to a close academic community than a large selective campus.
The school describes its curriculum as challenging, rigorous, engaging and broad, set inside a caring community that wants students to become independent thinkers, emotionally resilient, empathetic and socially responsible. The library sits at the centre of that academic culture, and published performance data is consistently strong, including +0.68 Progress 8 and 96.8% grade 5+ in English and maths.
Caistor's sixth form has a clear identity of its own. Casterby House provides teaching, study and social space, with the Lower Lindsey Dining Room's Coffee Club adding another base during the day. The Personal and Professional Development programme pushes students into leadership, enterprise, mentoring, performing arts, societies and volunteering, including local community placements.
Year 7 entry is smaller than many grammar schools, with 96 places. Applicants sit two school-administered verbal reasoning papers, and the published eligibility score for September 2027 entry is 220 or more across the two tests. Qualified in-catchment applicants living within 6.5 miles are prioritised before out-of-catchment applicants, with up to 12 main-round places reserved for Pupil Premium applicants, so address and eligibility evidence matter alongside the test result.
