How guides get written, checked and corrected

1 · Primary sources only

Exam fees come from the certification body's own store on a stated date. Salary figures come from the U.S. Bureau of Labor Statistics; where BLS has no matching occupation, the guide says so instead of quoting a recruiter's blog. Survey and self-reported numbers are labelled as exactly that, because they skew high. Study-time estimates come from documented learner experience and official training-hour recommendations, not best-case marketing claims.

2 · A named human writes it

Every guide carries one author with a real byline, credentials and a contact route. The research process uses modern tools, but every guide is edited, fact-checked and approved by a person who takes responsibility for the verdict. If a guide says “skip this certification”, that is an editorial judgment someone is willing to defend — not autogenerated filler.

3 · Advertising is separated from editorial

Display ads are served programmatically and are always labelled “Advertisement”. No advertiser sees a guide before publication, no verdict is for sale, and sponsored posts are declined. No certification body or training provider pays for coverage or placement. Affiliate links, where used, are disclosed in the sentence that carries them.

4 · Corrections are dated, not quietly edited

Certification prices and requirements change constantly. When a figure changes, the guide is updated and the change is stamped on the page — every article carries a last-updated date. Substantive corrections are logged. Report one and expect a reply within two business days.
