What a contractor license exam actually tests

A contractor license exam is rarely a single exam. Almost every licensing state runs two. A business and law exam covers the rules of operating: contracts, payroll, liens, insurance, licensing, and safety records. A trade exam covers the classification you applied under. Pass one and fail the other and you are not licensed.

Boards publish content outlines for both, and those outlines are the single most useful study document nobody reads. They tell you exactly how many questions come from each subject area. Every figure below is pulled from the board’s own outline or its testing vendor’s candidate bulletin, checked August 22, 2026.

What is on the exam, board by board

Exam Questions Time and format Largest single block
NASCLA Commercial General Building 115, need 81 330 min, open book Procurement and contracting, 31 items
California Law and Business Not published 3.5 hours, closed book Contract requirements and execution, 21%
South Carolina Business Management and Law 50, need 35 125 min Contracts and agreements, 12 items
Alabama general contractor Business and Law 50, need 70% 120 min Licensing, 8 items
Texas journeyman electrician 80 scored, need 70% 240 min Wiring methods and materials, 18 items
Texas journeyman plumber 90 written, plus shop work Written and hands on Scaled drain and vent build (2018 course)
Illinois roofing qualifying party Not published Not published Not published
Pennsylvania home improvement None None Registration, not examination

Two boards deserve a note. Illinois hands its outlines to Continental Testing, which does not publish them. Arizona publishes its outlines per exam through PSI rather than in the bulletin. Neither board states a question count up front. Arizona does publish its fees: $61 for the Statutes and Rules exam, which runs online only, and $66 for one trade exam.

TSBPE’s review course, dated November 2018, is what describes that scaled two story build. It exempts one group: a current Tradesman Plumber-Limited licensee tests in writing only.

SimplyWise Cost Estimator turns a photo into an itemized, branded estimate in about 6 seconds, with material, labor, and fee lines broken out.

Paperwork outweighs the trade on most outlines

Line the outlines up and the pattern is hard to miss. On the NASCLA exam, procurement and contracting requirements carry 31 of 115 items. Concrete, masonry, metals, and wood together carry 21.

California’s Law and Business exam splits into seven sections. The two largest are contract requirements and execution at 21% and employment requirements at 20%. That is 41% of an exam that exists alongside a separate trade exam. South Carolina puts contracts and agreements at 12 of 50 items and estimating and bidding at 10. Alabama leads with licensing at 8 of 50, then payroll and taxes and contracts at 6 apiece.

So fifteen years of running crews will not carry you through the half that decides the result. The trade portion rewards what you already do. The business portion tests the part of the job most contractors delegate or improvise.

Estimating and bidding is on the test and on the calendar

Estimating shows up in every business outline for a reason: it is where money leaks. SimplyWise Cost Estimator turns a photo into an itemized, branded estimate in about 6 seconds, with a unit, quantity, and price on every line. Pricing is $29.99/mo or $239.99/yr, about $20/mo on annual, with a 7-day free trial.

How to study for the exam you are actually sitting

  1. Download the outline before any prep course

    Find the candidate bulletin for your exact contractor license exam and classification. It names the subject areas, the item count per area, and the reference list behind the questions.

  2. Weight your hours to the item counts

    If contracts carry 12 of 50 items, contracts get a quarter of your study time. Most candidates over study the trade because it is the comfortable half.

  3. Find out whether your exam is open book

    The NASCLA exam is open book and hands out a physical blueprint packet at the testing center. California’s Law and Business exam is closed book, with no reference material allowed.

  4. Buy the exact reference editions listed

    Bulletins name the edition. South Carolina writes its business questions from the NASCLA Contractors Guide, South Carolina Commercial 9th Edition. Code books in particular must match.

Usually two. A business and law exam covering contracts, payroll, liens, and licensing, plus a trade exam for your classification. Both are required in California, South Carolina, and Alabama.

What is the hardest part of the exam?

The business half, by the numbers. Contracts and procurement carry the largest item counts on the NASCLA, California, and South Carolina outlines.

It depends on the exam. The NASCLA Commercial General Building exam is open book and supplies a blueprint packet onsite. California’s Law and Business exam is closed book.
