Katherine Warington School
Harpenden, AL5 5FH · Hertfordshire · secondary school
32nd of 78 secondary schools in Hertfordshire we can score, 82 in total — the rest without enough published data. Local and same-phase on purpose: a national table mostly measures who attends.
Its results hold up when the comparison narrows to schools whose pupils have similar backgrounds — 7.9/10 against 824 of them, against 8.2/10 nationally. So this is not simply a reflection of who attends. 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 | 52 | 35% | 1.81 |
| Grade 5+ English & maths 2024/25 | 59.5 · 81 | 30% | 2.44 |
| Progress 8 2023/24 | 0.48 · 83 | 25% | 2.07 |
| Attainment 8 2024/25 | 54.8 · 85 | 10% | 0.85 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.
Get to know the school
How it's doing. The school is rated Good by Ofsted, last inspected in 2024. In 2024/25, 59.5% of pupils achieved Grade 5 or above in English and maths. Attainment 8 was 54.8, compared to the national median of 44.6. Progress 8 was +0.48 in 2023/24, indicating pupils did better than those nationally who started from the same place. Its results hold up when the comparison narrows to schools whose pupils have similar backgrounds, so they are not simply a reflection of who attends (7.9 out of 10 against similar schools, 8.2 out of 10 against all schools).
Getting in. What that means is that you cannot determine if the school is full or has room for new students based on the available data.
Worth asking on a visit. How does the school support pupils in developing their individual interests outside of core lessons? What specific extracurricular opportunities are currently available to students? How does the school ensure that the Good inspection rating translates into daily classroom practice?
