Data and methodology
Source notes, update context and caveats for the school data shown on MySchoolHub.
MySchoolHub combines official school records, DfE performance data, Ofsted inspection information and local admissions research so parents can compare schools in one place.
Last reviewed: 23 May 2026. The notes below explain where each major field comes from, why some values can be missing, and why rankings should be treated as decision support rather than a guarantee of future outcomes or admissions eligibility.

Why data can be missing
- Some measures are unavailable because the school has no eligible cohort, has a very small cohort, does not cover that key stage, or the DfE suppresses values for privacy and statistical reliability.
- Independent schools and some specialist providers can have thinner public performance coverage than mainstream state-funded schools. MySchoolHub shows missing values as unavailable rather than filling gaps with estimates.
How to read Ofsted data
- Ofsted overall effectiveness is shown where the source data includes it. From September 2024, graded inspections of state-funded schools no longer include a single overall effectiveness judgement, so newer inspection records may show judgement areas without an overall grade.
- Local authority good/outstanding percentages are calculated only from schools with recognizable overall effectiveness values, including both text grades and numeric Ofsted codes in the imported data.
How to use rankings and comparisons
- Rankings and side-by-side comparison are useful for shortlisting, but they should not be used alone. A practical school decision also needs admissions rules, distance, travel, pupil needs, curriculum fit and current school context.
- Historical performance does not guarantee future results or admission eligibility. Always verify admissions arrangements, oversubscription criteria, supplementary forms and deadlines with the local authority or the school.
Corrections
If a figure on a school profile looks wrong, tell us the URN and what you expected. We check against the source release and correct it.
