Check the area around this school
3rd 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 475 schools whose pupils have similar backgrounds — a tougher field — and it places 8.0/10 among them, against 9.3/10 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 |
|---|---|---|---|
| Grade 5+ English & maths 2025/26 | 82.6 · 95 | 46% | 4.39 |
| Progress 8 2023/24 | 0.67 · 90 | 38% | 3.46 |
| Attainment 8 2025/26 | 63.0 · 94 | 15% | 1.45 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.
