This exam may also include questions on the following subjects:
In addition to the trade-specific examination, you are required to pass the Contractor Management Survey Exam offered by PSI.
Sample questions are based on the PSI publication titled “29 CFR PART 1926 Selections, as of June 2013” (highlighted in green above).
This file contains approx. 800 sample questions.
