25th of 54 secondary schools in Lincolnshire we can score. Local and same-phase on purpose: a national table mostly measures who attends.
Narrow the comparison to the 764 schools whose pupils have similar backgrounds — a tougher field — and it places 3.6/10 among them, against 5.8/10 nationally. Both figures are results only, without the inspection grade. A lower figure here means a stronger comparison group, not a weaker school.
How this is worked out
| Measure | Percentile | Weight | Adds |
|---|---|---|---|
| Ofsted | 14 | 35% | 0.50 |
| Grade 5+ English & maths 2025/26 | 60.7 · 82 | 30% | 2.47 |
| Progress 8 2023/24 | -0.43 · 19 | 25% | 0.48 |
| Attainment 8 2025/26 | 54.7 · 84 | 10% | 0.84 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.

How it's doing
In 2024/25, 53.6% of pupils achieved grade 5 or above in English and maths. Attainment 8 was 53.1, compared to the national median of 44.6. Progress 8 was -0.43 in 2023/24, indicating pupils did worse than those nationally starting from the same place. Narrow the comparison to the schools whose pupils have similar backgrounds — a tougher field — and it places 2.4 out of 10 among them, against 5.3 out of 10 nationally. Ofsted inspected the school in April 2026 under the new framework, which grades areas separately without an overall grade.
Beyond the classroom
Pupils can join Theories of Everything, Chess Club, and Quiz Club, alongside choirs, instrumental groups, and a wind band.

What Ofsted said about The Boston Grammar School
Overview
The report describes a school where pupils are proud of their community and feel safe within a "positive, caring environment." While attendance and behaviour are rated at a "Strong standard," other key areas including the curriculum, teaching, and achievement are assessed at the "Expected standard" or "Needs attention."
Strengths
- Attendance rates are "above national averages" and rising, with persistent absence "below average" due to "highly effective approaches."
- Pupils’ behaviour is "excellent," with students moving "calmly and purposefully" and bullying being "rare."
- Leaders provide "strong strategic direction" for an "ambitious and well‑sequenced curriculum."
- There is a "comprehensive personal development programme" offering numerous leadership and extra-curricular opportunities.
- Staff feel "highly valued" and benefit from "high‑quality professional development."
Areas to improve
- Leaders should ensure achievement is raised, particularly for "high prior attainers," through "sufficient challenge" and effective checks of learning.
- Teachers must meet all pupils’ needs more fully by making "consistently precise and effective adaptations" to the curriculum and teaching.
Safeguarding
The safeguarding standards are met, with an "open culture in which safeguarding is everyone's responsibility" ensuring pupils are made safer and feel safe.
