Editorial standards

Use public sources

Each factual claim cites a public source, such as a published standard, official guidance, or an open-access article, so you can look it up.

Check every claim

Before a lesson or question is published, two independent reviewers check each claim against the cited pages of its source. Both must find that the source supports the claim. A third reviewer then checks their reports. If either reviewer cannot confirm a claim, the item stays unpublished until it is corrected and checked again.

Say what is ready

Draft work stays marked as draft. Published course counts refer only to material learners can access.

Fix errors

Confirmed factual errors take priority. Paid courses will include a public correction log.
