Understanding how we calculate school rankings and scores to help you make informed decisions
Explore Our ProcessFindMySchool does not produce a single “overall” score. Instead, we publish separate rankings for each performance category so you can compare schools on the measures that matter most to your family. A school might rank highly for A-levels but sit lower for GCSE results, or vice versa — our approach lets you see both.
Every ranking is built from official government data and covers all eligible schools in England. Click any card below to see exactly which metrics feed into that ranking.
Based on KS2 SATs results — reading, writing, and maths performance for state-funded primary schools
Top grades achieved, Attainment 8, Progress 8, and EBacc performance
Percentage of A*, A*-A, and A*-B grades achieved across all subjects
Blended ranking where A-level performance is weighted more heavily than GCSE
Applications, offers, and acceptances to the University of Oxford and University of Cambridge
Our proprietary 1–10 quality metric combining Ofsted and ISI inspection data
Ranks state-funded primary schools by KS2 SATs outcomes. The following metrics are combined:
No inspection component: The primary ranking is based entirely on academic results and does not include Ofsted or ISI data.
State schools only: Independent primary schools do not sit government KS2 SATs and therefore do not appear in this ranking.
Ranks secondary schools by GCSE performance using the following metrics:
Ranks sixth forms and schools with A-level provision by grade distribution:
A blended ranking for schools that offer both A-levels and GCSEs. It draws on the same metrics used in the individual A-level and GCSE rankings:
Note: Only schools with published data for both A-levels and GCSEs appear in this ranking.
Ranks schools by their success in gaining places at the University of Oxford and the University of Cambridge:
In addition to these academic rankings, every school receives an FMS Inspection Score — a separate 1–10 quality metric based on Ofsted and ISI inspection data.
The FMS Inspection Score is FindMySchool's proprietary quality metric. It is not an official Ofsted or ISI rating. Instead, it provides a single comparable number across all ~25,000 schools in England, regardless of which inspection body assessed them.
Every school receives a numeric score from 1 to 10, mapped to five quality bands:
Different inspection bodies use different grading systems. Ofsted uses a 4-point scale (Outstanding, Good, Requires Improvement, Inadequate), while ISI uses Met/Not Met judgments with qualitative descriptors. The FMS Inspection Score bridges this gap by converting both systems into a single standardised metric, allowing parents to compare any school in England on a like-for-like basis.
We do not publish the specific weightings used to calculate the score. This is intentional — disclosing exact weights could incentivise schools to optimise for the metric rather than genuine educational quality.
Disclaimer: The FMS Inspection Score is an independent analysis by FindMySchool. It is not endorsed by or affiliated with Ofsted or ISI. Always refer to the official Ofsted or ISI report for the full picture of a school's inspection outcome.
We use only official government data sources to ensure accuracy and reliability. All data is verified and cross-referenced to maintain the highest standards of integrity in our rankings.
