Free materials worth using

Compiled by the Sitonce editorial team from the PSI Candidate Information Bulletin, NASCLA's own published material and the federal standards named belowUpdated 2 min readFacts verified 4 September 2026
The short answer

The candidate bulletin, 29 CFR 1926 on the OSHA site and the participating state agency pages are free, authoritative and directly relevant. Free question banks are worth less because they rarely match the published weighting.

Some free material is better than anything sold. Some is worse than nothing.

Worth using

ResourceWhy
The candidate bulletinThe authority on format, rules, fees and the reference list. Free and definitive.
29 CFR 1926 on the OSHA siteThe full construction standards, searchable, current, and behind about a quarter of the exam.
State licensing agency pagesWhat your state actually does with the exam result, which no prep provider can tell you reliably.
NASCLA participating state listWhich states accept the examination, kept current by NASCLA.
Searchable OSHA text is a study tool

Working practice questions with the OSHA regulations open in a browser is how you find out which sections you keep returning to, and those sections are what you tab in the printed copy you take to the exam.

Worth less than it looks

Free question banks. They cluster on whatever is easy to write, which is usually safety figures, and they rarely reflect a blueprint that puts 31 of 125 questions in Procurement and Contracting.

Used for format familiarity and index-building they are fine. Used as a score predictor they mislead.

What free cannot replace

The references themselves. You take them into the exam, and no free substitute exists for owning the approved editions.

That is the irreducible cost of this exam, and it is larger than the exam fee.
