Every fact here was checked at the source, and is checked again when the source moves.
The fact base, the watcher and the correction rule, in plain words.
Nothing on this site states a fact that is not in its fact base. The fact base is a set of files in the open, one record for every claim the guides, templates and glossary make: the exact wording, the document it comes from, the paragraph or page it sits at, and the date it was last checked against that document. The guides cite those records, and the numbered references at the foot of every guide are those records, with a link to the source.
Where the facts come from #
Every fact rests on a primary document: the statutory guidance, the regulator's own pages, the law as enacted, the published standard. Not a summary of it, not a news report about it, not a training provider's slide. Where the source says "should", the fact says "should". Where the source is silent, the fact says so, because what the guidance does not require is as useful to a school as what it does.
The watcher #
A small program reads every watched source each Monday and compares the text with the copy it kept the week before. When the wording changes, it reports which facts cite that document and which pages, clauses and lessons cite those facts. The change is then read by a person, against the document itself. Most weeks it is a typo or a reformat, and nothing moves. When something has changed in substance, the fact is updated with a new check date, the pages that rely on it are revised, and a dated entry goes on the What's changed page. Until a page has been revised, it carries a notice at the top saying so.
The correction rule #
If a fact here is wrong, it is corrected in the open: the record changes, the pages change, and a dated line on What's changed says what was wrong and what it now says. Nothing is changed quietly. If you find something that does not match the source, say so through the contact page and name the document; the check is the same whoever asks for it.
What the dates mean #
Every guide shows the date it was last reviewed. That date moves only when a person has read the guide against its sources again, not when the page was last edited for style. The templates carry the version of the clause library they were built from, so a school can tell at a glance whether its own copy is current.
