OSHA 10 Construction Practice Test (Adaptive Mock)
The OSHA 10-Hour Construction course ends with a final check of what you learned. These questions follow the federal construction standards in 29 CFR 1926. Each attempt draws 15–20 questions and adapts to your last score.
Adaptive Practice Test
15–20 Questions Drawn From 152
Every attempt is a new test: questions are drawn at random and the answer order is shuffled. Score 80% or more and your next test moves up a level; score under 50% and it eases back. Your level is saved only in this browser.

How This Practice Test Works
- Each attempt draws 15–20 questions at random from our pool of 152 and shuffles the answer order. Score 80% or more and the next test moves up a difficulty level; under 50% and it eases back.
- After every answer you see an explanation and the 29 CFR 1926 reference behind it.
- We use 70% as a practice target. Authorised outreach trainers and online providers set their own quizzes; OSHA does not publish an exam bank.
- There is no sign-up. Your level is saved only in this browser.
These are original questions written by our editorial team from the published 29 CFR 1926. They are not real exam questions. Each question cites the 29 CFR section behind the answer. OSHA does not endorse Trade Exam Hub, and outreach cards come only from authorised trainers.
What the Question Pool Covers
Every question cites the rule behind its answer. Counting those references shows where the pool puts its weight:
