If you’re a general contractor looking to work across state lines, the NASCLA exam is one of the most valuable credentials you can earn. Instead of taking a separate trade exam in every state where you want to work, passing the NASCLA exam satisfies the trade exam requirement in all participating states at once.
What Is NASCLA?
NASCLA stands for the National Association of State Contractors Licensing Agencies. The organization developed the Accredited Examination for Commercial General Building Contractors as a standardized test that multiple states agree to accept.
The key word here is “commercial general building.” The NASCLA exam is specifically for general contractors doing commercial construction. It doesn’t cover residential-only contractors or specialty trades like electrical, plumbing, or HVAC.
Which States Accept the NASCLA Exam?
As of 2026, the NASCLA accredited examination is accepted in approximately 17 states. These include Alabama, Arkansas, Georgia, Louisiana, Mississippi, Nevada, North Carolina, Oregon, South Carolina, Tennessee, Utah, Virginia, and West Virginia, among others.
The list has been growing steadily over the past decade, and NASCLA actively works to add more states.
What the NASCLA Exam Covers
The exam tests your knowledge in these areas:
- Project management — Scheduling, planning, coordination of trades
- Estimating — Quantity takeoffs, cost estimating, bidding
- Contract administration — Contract types, change orders, claims
- Safety — OSHA requirements, hazard identification, safety programs
- Building codes — IRC, IBC, accessibility requirements
- Construction methods and materials — Foundations, framing, finishes, MEP systems
The exam uses a reference-book format. You’re allowed to bring approved reference materials into the testing center, so the test focuses more on your ability to find and apply information than on memorization.
Exam Details
- Format: Multiple choice
- Duration: Approximately 5 hours
- Fee: Around $300-$400 (varies by testing provider and state)
- Testing provider: PSI Services or Prometric (depending on the state)
- Passing score: Varies by state, but typically around 70%
How to Prepare
Study materials
- NASCLA Contractors Guide to Business, Law and Project Management — This is the primary reference book. Many states require you to use a specific edition.
- Practice exams — Available from several exam prep companies. These are valuable for understanding the format and timing.
- Pre-licensure courses — Many states require or recommend a course before you can sit for the exam.
Study tips
- Start with the reference book. Tab and highlight it thoroughly. The exam is open-book, so knowing where to find information quickly is more important than memorizing it.
- Take practice tests under timed conditions. Time management is a real factor in a 5-hour exam.
- Focus on codes. Building code questions make up a significant portion of the exam. Make sure you’re comfortable navigating the IBC and IRC.
- Don’t skip the business sections. Many test-takers focus on the technical content and underestimate the business, law, and project management sections.
Important Limitations
Passing the NASCLA exam does not mean you’re automatically licensed in every participating state. You still need to:
- Pass each state’s business and law exam (which covers state-specific regulations)
- Meet all other state requirements (experience, insurance, bonds, background checks)
- Submit a separate application and pay fees in each state
Think of the NASCLA exam as eliminating one barrier — the trade exam — across multiple states. It’s a significant time and cost saver, but it’s not a universal license.
Is It Worth It?
If you work in or plan to expand into multiple states, absolutely. Taking one exam instead of 5, 10, or 15 separate state trade exams saves thousands of dollars in fees and hundreds of hours of study time. Even if you currently only work in one state, having NASCLA on your resume gives you the flexibility to pursue opportunities in other states without starting the exam process from scratch.

State-by-State NASCLA Requirements
While all participating states accept the NASCLA exam, the additional requirements vary:
- Alabama: Must also pass the Alabama business and law exam. Requires 4 years of commercial experience and financial statements showing a minimum net worth.
- Arkansas: Requires the NASCLA exam plus the Arkansas business and law exam. Experience requirements vary by license class.
- Georgia: Accepts NASCLA for the trade exam. Requires a separate Georgia-specific business exam. Must show financial statements reviewed by a CPA for larger license classes.
- Louisiana: One of the most reciprocity-friendly states. NASCLA waives the trade exam. Still requires the Louisiana business and law exam and proof of $100,000 minimum net worth.
- Mississippi: NASCLA exam plus Mississippi supplemental exam. Requires 4 years of documented commercial experience.
- North Carolina: Accepts NASCLA exam. Also requires NC-specific business law exam. Must submit financial statements and meet net worth requirements based on license limit.
- South Carolina: NASCLA exam waives the technical portion. Still need the SC business and law exam. Requires references and experience documentation.
- Tennessee: Accepts NASCLA for the trade exam. Requires Tennessee business and law exam. Financial statement requirements vary by license classification.
- Utah: One of the most NASCLA-friendly states with streamlined processing for NASCLA exam holders.
- Virginia: Accepts NASCLA exam. Requires the Virginia business exam. Different license classes have different experience and financial requirements.
Always verify current requirements directly with the state licensing board before applying.
After You Pass: Next Steps
Once you’ve passed the NASCLA exam, here’s a practical roadmap for leveraging it:
- Get your results in writing. Make sure you have official documentation of your passing score. You’ll need to submit this with each state application.
- Prioritize your target states. Don’t apply everywhere at once. Start with the states where you have the most business opportunity or where you already have projects pending.
- Prepare for business and law exams. Each state requires its own business and law exam. These are typically shorter (2-3 hours) and cover state-specific regulations, lien laws, and business practices. Study materials are state-specific.
- Line up your insurance and bonds first. Many states won’t process your application without proof of insurance and bonds. Getting these in place before you apply avoids delays.
- Budget for the full cost. Between the NASCLA exam fee, state application fees, state exam fees, insurance, and bonds, expect to spend $1,500-$3,000 per state. The NASCLA exam itself saves you one exam fee per state, which adds up significantly across multiple states.
- Keep your NASCLA certificate accessible. You’ll need copies for every state application. Store it digitally and keep the original in a safe place.
NASCLA vs. State-Specific Exams
If you only plan to work in one state, taking the NASCLA exam may not be necessary — you can simply take that state’s own trade exam. The NASCLA exam makes the most financial sense when you plan to work in 3 or more participating states. Here’s a rough cost comparison:
- Single state: State trade exam ($200-$400) is cheaper and faster
- 2 states: NASCLA ($300-$400) starts to break even when you factor in study time
- 3+ states: NASCLA saves $200-$400 per additional state in exam fees alone, plus dozens of hours of study time per state
The investment in NASCLA pays dividends over your entire career, since you’ll never need to retake a trade exam in any participating state.
