Frequently Asked Questions

Which states accept the NASCLA exam?

16 states and territories accept the NASCLA Commercial General Building Contractor exam: Alabama, Arizona, Arkansas, Georgia, Louisiana, Mississippi, Nevada, New Mexico, North Carolina, Oregon, South Carolina, Tennessee, Utah, Virginia, West Virginia, and the U.S. Virgin Islands. Pass it once and you can apply it toward the trade portion of licensing in any participating state — most also require a short state-specific supplement covering business and law.

What is the NASCLA exam?

The NASCLA Accredited Examination is a standardized Commercial General Building Contractor exam delivered at PSI test centers. It has 115 scored questions across 12 trade areas, runs 5 hours 30 minutes, and requires 81 correct answers to pass. It is open book — you can bring up to 24 approved reference books plus a calculator — so knowing how to find answers fast matters as much as knowing the material.

Does one subscription cover all three exam systems?

Yes. EstatePass Contractor includes all three exam lines — NASCLA, Florida, and California — under a single subscription. That is 7,600+ practice questions in total, and you can switch lines anytime while your progress is tracked separately for each.

How many questions are on the contractor exam?

It depends on your exam system. The NASCLA Accredited Exam is a single 115-question exam. Florida's General Contractor license requires three separate exams totaling 240 questions (Business & Finance 120, Contract Administration 60, Project Management 60). California's CSLB Class B requires two 115-question exams (Law & Business plus the Class B Trade exam), 230 questions total.

Is the contractor exam open-book?

The NASCLA exam and all three Florida exams are open book — you can bring approved reference materials into the testing center, so tabbing and highlighting your books is a core exam skill. California is the big exception: both CSLB exams are entirely closed book. Hawaii's state exams are also closed book.

What does California's closed-book exam mean?

California does not allow any reference materials in the testing room. Both CSLB exams — Law & Business and the Class B Trade exam — must be answered from memory, with about 3.5 hours each and a 73% passing bar. That changes how you study: instead of practicing lookups, you drill recall until contract rules, payroll math, and trade facts are automatic.

How much does the contractor exam cost?

Exam fees range from $110 to $450 depending on the exam system and state. The NASCLA exam is $110 per attempt through PSI, Florida is $295 through Pearson VUE, and California is $450 through PSI for the CSLB. Additional costs include application fees ($50-$300), background checks ($40-$100), surety bonds, and insurance — total licensing costs typically run $500 to $2,500.

Which states require a contractor license?

Most states require some form of contractor licensing before you can legally take on construction work above a dollar threshold. EstatePass covers the three exam systems used across 18 jurisdictions: the NASCLA Accredited Exam (16 states and territories), Florida's state-run exams, and California's CSLB exams. Requirements, license classifications, and project thresholds vary by state — check your state licensing board for specifics.
