Exam structure, topics, study areas and official resources.
The B-1 General Commercial Contractor exam is PSI's trade test for Arizona's B-1 license, shared with B-2, KB-1 and KB-2: 100 questions, 240 minutes, 70 percent to pass, open book. The references allowed in the exam are the 2018 International Building Code, the 2018 International Residential Code and OSHA's 29 CFR 1926. Try the free sample above: no sign-up, with a written explanation on every question.
PSI's content outline for the B-1 exam (effective 5/9/2024), linked from the Arizona bulletin for B-1, B-2, KB-1 and KB-2, sets the format: 100 questions, 240 minutes, 70 percent, open book, with a non-programmable calculator. The references allowed in the exam are the 2018 International Building Code, the 2018 International Residential Code and 29 CFR 1926 for jobsite safety. Code questions are based on the listed editions, so study the 2018 codes even though newer editions exist. The outline also lists commercial textbooks for preparation; those are not allowed in the exam room.
The outline splits the exam into 10 areas. Concrete is the heaviest (14), followed by metals (13), safety (12) and carpentry (12); masonry and thermal and moisture protection carry 10 each, sitework and the general building code 9 each, finishes 6 and doors and windows 5. Commercial work shows up in the scenarios: steel joist and decking erection under Subpart R, special inspections, shotcrete and slab rules from IBC Chapter 19, fire-rated openings and safety glazing, occupancy groups, construction types and egress widths.
The Arizona bulletin links all four classifications to one shared outline, so they take this one PSI trade exam; the residential B license has a separate outline built on the IRC. Every Arizona license also requires the SRE, AZ ROC's separate open-book law exam, and business topics are not tested on this trade exam — budget for those preparations separately.
The full LICENA course is 500 questions in five blocks, every answer explained with its code citation. At 30 questions a day that is under three weeks: a first pass to find what you do not know, a second on weak blocks, then the timed final mirroring the real 100-question, 240-minute format. Open book rewards navigation — knowing that soils and foundations are IBC Chapter 18, concrete Chapter 19, masonry Chapter 21, steel Chapter 22, wood Chapter 23, glazing Chapter 24 and egress Chapter 10, and that steel erection safety is Subpart R of 29 CFR 1926 — and drilling builds that reflex. Pair the bank with the Arizona SRE practice (also required) and our guide to Arizona's contractor exams.
