How we know this.

What we actually do

We read individual advertisements, one at a time. Search result pages truncate the body of a job advertisement, so coding from a results list produces false negatives. Every count on this site comes from opening the advertisement itself. That is slow, and it is the only way the numbers mean anything.

We load the regulator's own form, not its website. This one changed an answer. Six of the seven National Boards that require a curriculum vitae for registration say nothing about it on their public pages. The requirement lives inside the application form. Reading the website alone would have understated it by a factor of three.

We state the sample size, always. A number without a denominator is marketing. Fourteen healthcare advertisements, fourteen technology, eighteen mining, twenty-eight regulator forms. Small samples, honestly labelled, and we say so where a count rests on a handful of cases.

We publish what we could not confirm. Five National Boards no longer publish their application forms at all, so their requirement is unknown to us and we say unknown rather than guessing. The largest nursing cohort is in that group.

A search snippet is not a source. Twice in this research a snippet said something the loaded page did not contain, and one of those was about to become a published claim. Both were caught by loading the page.

What we publish and what we hold back

We publish the conclusions and the counts. We do not publish the coded dataset, the advertisement URLs, or the working files behind them. That is partly commercial and partly practical: the value is not in any single number, it is in being able to answer the follow-up question, and in being able to check the number again when a regulator changes a form.

Our specimen resumes are published as watermarked images rather than downloadable files, for the same reason. You can read the work. You cannot repurpose it.

The part that matters most

Anyone can copy a number off this page. The number will be right until a board revises its form, a regulator is restructured, or a convention shifts, and then it will quietly be wrong. Western Australian mines safety regulation moved out of DEMIRS on 1 July 2025, and training providers' own marketing still names DEMIRS today.

We know the retrieval route for every claim here, so we can check it again. That is the thing worth paying for, and it is the one thing that cannot be lifted.

When we get it wrong

We will. When a claim on this site turns out to be wrong or out of date, we correct it and we do not quietly delete it. Anything you find that looks wrong, send it to us and we will check it against the source and tell you what we find.
