The source, and how we filtered it

How we filtered itEngland: open GIAS establishments whose type is a school (LA-maintained, academies and free schools of every kind, state special, non-maintained special, independent, independent special, PRUs, LA nurseries and sixth-form centres); website is GIAS SchoolWebsite (high). Scotland: the 'Open Schools' sheet with its Website Address column (high), plus the independent schools register, which has no websites. Wales: the Maintained, Independent and PRU sheets of the address list, which has no websites, joined to GIAS's Welsh record on LA code plus establishment number for a website at medium confidence. Northern Ireland: the Institutions Search export (Open status; Primary, Secondary, Grammar, Nursery, Special, Independent and Preps), which has no websites. Any blank with a DfE URN is filled from Wikidata P856 on P2253 (low). Social media pages and non-URLs are dropped with a note. Paths are cut to the root unless the host is shared or is a hosting platform. Ordered by nation, local authority, then name.
Instead ofGIAS's Welsh records as the Welsh population: they are not Wales's register and are out of date, so they supply a website only.

The filtering is ours and is disclosed as ours. The source published a list; the decision about which rows of it belong in a cohort was a judgment call, and it is written down so somebody can disagree with it.

What the cohort earns, dimension by dimension

The mean share of each dimension’s available points that this cohort earned. Low here means the whole sector is weak on it, not that one site dragged an average down. The per-site spread is in the dataset.

How much of each site we read

The cap is 32 URLs and it is a ceiling, not a promise. A portal whose every link points at a different host yields one page; a university yields the full sample. The median here is 32, the range 1–32, published so that "we sampled 32 URLs per site" cannot become a claim the data does not support.

268 sites in this cohort served a certificate we could not verify. They were read anyway and scored normally, because reporting no response for a site every browser loads would describe our TLS stack rather than the site, and each one carries the finding in its row.

Every site

Every 29,692, named, with a report for each

Whether or not it has been scanned. Rows with no website on record, sites that were unreachable and sites that turned us away stay in the table with the reason on them, and none of them enters an average: dropping them would shrink the population to the part that was easy to measure. A few points between two neighbors is noise. The box filters every row in the cohort, not only the page you are on; click a header to sort the rows on this page by name or by score.
