NASCLA vs. State Exam: Which One Should You Take?
If your licensing agency accepts the NASCLA commercial exam for the classification you need, NASCLA is usually the stronger choice when you expect to pursue licenses in multiple participating jurisdictions. If you need only one jurisdiction—or NASCLA does not cover your classification—the state-specific route may be more direct.
NASCLA is not a national contractor license. Passing it can replace or otherwise satisfy part of a participating agency's trade-exam pathway, but each licensing agency still controls the license and its remaining requirements.
Quick answer: which exam fits you
| Your situation | Route to check first |
|---|---|
| You'll pursue licenses in two or more NASCLA-participating jurisdictions, and each accepts NASCLA for your classification | NASCLA. One passing result can reduce duplicate trade testing, subject to each agency's rules. |
| You only need one jurisdiction and its state exam directly serves your classification | That jurisdiction's exam may be the more direct route. |
| You're licensing in Georgia as a General Contractor | NASCLA is part of Georgia's General Contractor exam path, together with Georgia Business & Law. |
| You're applying for California B-General Building and have not held an equivalent out-of-state license in good standing for the previous five years | California's state route. The NASCLA trade-exam waiver has additional eligibility conditions. |
| Oregon | NASCLA can waive Oregon's 16-hour pre-license training, but you still take the Oregon laws/rules/business exam. |
| Utah general contractor | NASCLA can satisfy Utah's two-year/4,000-hour experience requirement; it is not a trade-exam waiver because Utah does not use a general-contractor trade exam. |
| Specialty trade, or your classification is outside the NASCLA commercial-general-building scope | The state/agency-specific route unless a separate NASCLA accredited exam applies. |
| You're not sure your classification qualifies | Don't register yet. Run the 4 checks first. |
A separate state business-and-law, rules, or other licensing requirement often remains. The exact requirement depends on the agency.
What NASCLA does in each participating jurisdiction
NASCLA currently lists 20 participating agencies in 17 states plus the U.S. Virgin Islands for the Accredited Examination for Commercial General Building Contractors. Participation does not mean the same thing in every jurisdiction, and it does not mean every contractor classification is covered.
The table below uses the state board's own current page where a clear rule was available. Where NASCLA's listing is more specific than the board page—or the sources do not line up cleanly—the row tells you to confirm before relying on it.
| State / agency | How NASCLA is used | Important condition or remaining step | Source |
|---|---|---|---|
| Alabama — Home Builders Licensure Board | NASCLA lists the board as a participating agency as of March 17, 2025. | The board's current unlimited-home-builder materials still describe Alabama Home Builders testing. Confirm exactly how NASCLA is applied to the license you want before registering. | NASCLA listing · HBLB applicant FAQ |
| Alabama — Licensing Board for General Contractors | NASCLA lists the board as participating. | Alabama says all prime-contractor applicants must take its Business and Law exam. Confirm the NASCLA classification match with the board. | NASCLA listing · AL board application page |
| Arizona Registrar of Contractors | NASCLA is an option in lieu of the state trade exams for B-1 and B-2. | The NASCLA exam date on the transcript must be within the previous 2 years. | NASCLA Arizona |
| Arkansas Contractors Licensing Board | NASCLA says Arkansas administers the exam in lieu of candidates providing appropriate experience on the application. | Arkansas's current commercial application still says major classifications such as Building require 5 years of experience. Because those sources do not align cleanly, confirm the effect of NASCLA with the Arkansas board before relying on it. | NASCLA Arkansas · Arkansas commercial application |
| California Contractors State License Board | A NASCLA pass can support a waiver of the B-General Building trade exam. | You must have held an equivalent general-building license in another state in good standing for the previous 5 years, submit license verification, request the waiver, and have NASCLA results sent to CSLB. | CSLB reciprocity requirements |
| Florida Construction Industry Licensing Board | NASCLA can be used in the endorsement route for Certified General, Building, or Residential Contractor licensure. | Florida still requires the Business & Finance exam and an exam covering the Florida Building Code, or an approved alternative described by DBPR, plus the other endorsement conditions. | Florida CILB endorsement application · DBPR FAQ |
| Georgia State Licensing Board for Residential and General Contractors | The NASCLA exam is the trade examination used for Georgia General Contractor and General Contractor Limited Tier applicants. | Georgia also requires its Business & Law examination for the exam route. | Georgia application · PSI Georgia bulletin |
| Louisiana State Licensing Board for Contractors | The NASCLA Building exam can give exam credit for Building Construction and/or Residential Construction. | Louisiana handles Business and Law as an online course rather than a graded pass/fail exam. Current LSLBC guidance describes Business and Law as a one-hour online course with an exam on its contents at the end. See the Louisiana board's qualifying-party guidance (PDF, checked October 5, 2026); confirm the current completion requirement with the board. | Louisiana application guidance |
| Mississippi State Board of Contractors | A general building contractor may use NASCLA instead of the Mississippi Building Construction trade exam. | Mississippi still requires its Law and Business Management exam. | MSBOC FAQ |
| Nevada State Contractors Board | NASCLA may waive the trade exam for B General Building and B-2 Residential and Small Commercial. | Nevada's qualifying individual still must meet the Board's other requirements; the Business and Law/CMS exam remains required unless separately waived under an applicable rule. | Nevada FAQ · Nevada license requirements |
| New Mexico Construction Industries Division | NASCLA lists the exam as accepted in lieu of the trade exam for GB-98. | NASCLA says the candidate must show at least 1 year licensed and in good standing in another state. New Mexico separately requires qualifying-party applicants to satisfy its applicable exam/Business-and-Law process. | NASCLA New Mexico · NM RLD licensing process |
| North Carolina Licensing Board for General Contractors | The North Carolina board says it accepts NASCLA for the Building classification. | NASCLA's own agency page also mentions Residential and says the exam must have been passed within 2 years. Because the board's current FAQ is narrower, confirm with NCLBGC before relying on NASCLA for Residential. | NCLBGC FAQ · NASCLA North Carolina |
| Oregon Construction Contractors Board | Passing NASCLA lets an applicant skip the 16-hour pre-license training. | You still must pass Oregon's contractor exam covering laws, rules, and business practices. | Oregon CCB license page |
| South Carolina — Contractors' Licensing Board | NASCLA is a national technical-exam option for commercial licensing. | South Carolina says all applicants must pass the Business Management & Law for Commercial Contractors exam. NASCLA says commercial exam scores must be within 3 years to be accepted. | SC CLB licensure · NASCLA SC CLB |
| South Carolina — Residential Builders Commission | NASCLA can waive the Residential Builder technical exam. | The NASCLA exam must have been passed within 3 years; one year of qualifying residential experience and the Business Management & Law exam still apply. The resulting exam-waiver license is limited for mechanical work. | SC Residential Builder |
| Tennessee Board for Licensing Contractors | Tennessee accepts the NASCLA National Commercial exam; its classification guidance identifies it for BC-B Commercial. | New contractor applicants must pass Tennessee Business and Law and meet the Board's remaining application requirements. | Tennessee contractor page |
| Utah DOPL — Construction Trades Bureau | NASCLA can satisfy the 2-year/4,000-hour experience requirement for a general contractor license. | Utah's general-contractor path has a separate Business & Law requirement unless the applicant qualifies under another listed alternative. | Utah general contractor requirements |
| U.S. Virgin Islands — DLCA | NASCLA lists DLCA as a participating agency. | DLCA materials available online are not consistent enough to reduce the current exam sequence to a simple NASCLA-vs-state choice. Confirm the current required exam combination with DLCA before paying. | NASCLA U.S. Virgin Islands · DLCA construction requirements |
| Virginia Board for Contractors (DPOR) | NASCLA describes its commercial exam as comparable to Virginia's Commercial Building (CBC) classification. | Virginia controls the class, specialty, experience, and business-exam requirements for the license sought. Confirm the exact route with DPOR. | NASCLA Virginia |
| West Virginia Contractors Licensing Board | NASCLA is on the participating-agency list, and the Board does not accept NASCLA exam scores/transcripts dated before September 1, 2013. | West Virginia has its own Business and Law examination and classification requirements. Confirm which trade classification your NASCLA result satisfies before registering. | NASCLA West Virginia |

NASCLA vs. a state trade exam at a glance
| Row label | NASCLA commercial exam | State-specific trade exam |
|---|---|---|
| What it is | A standardized commercial-general-building trade exam used or accepted by participating agencies | An exam tied to a particular state/agency and classification |
| Gives you a license? | No | No. Passing an exam is only one part of licensure. |
| Reusable elsewhere? | Potentially. A passing NASCLA result can be sent to participating agencies that accept it for the relevant classification. | Usually tied to that agency, unless a separate waiver, endorsement, or reciprocity rule applies. |
| Classification scope | Commercial general building, plus whatever a participating agency treats as equivalent | Whatever classifications that agency offers, including specialties |
| Business/law step | A separate state-specific requirement often remains | Depends on the jurisdiction and classification |
| Current NASCLA format | 115 scored questions + 10 unscored pretest questions; 330 minutes; 81 correct required; open book | Varies by state and classification |
The real choice isn't "national license vs. state license." It's one reusable trade-exam result vs. an agency-specific exam path, and every license is still issued under that jurisdiction's rules.
Is NASCLA a national license?
No. NASCLA says plainly that its Accredited Examination Program is not a license or certification. Passing can eliminate the trade-exam requirement at participating agencies, but you still apply to each licensing agency and meet its additional requirements.
NASCLA uses two terms you'll see on its participating-agency pages:
| Term | What it means |
|---|---|
| Administering agency | Uses a NASCLA accredited exam as its state-specific trade examination. A candidate may apply through the administering agency or through NASCLA. |
| Accepting agency | Accepts a NASCLA accredited exam as a waiver in place of its own state-specific trade examination. |
All administering agencies are also accepting agencies. Source: NASCLA FAQ.
Will you still need a business and law exam?
Often, but not always in the same form. NASCLA does not administer state Business and Law exams, and the NASCLA PSI bulletin tells candidates to follow each state agency's licensing process after the trade exam.
Examples differ:
- Georgia: General Contractor applicants using the exam route must pass Business & Law as well as the NASCLA trade exam.
- Louisiana: Business and Law is handled as an online course rather than a graded pass/fail exam.
- Nevada: the qualifying individual generally must pass the Business and Law/CMS exam in addition to the trade requirement.
- Oregon: NASCLA waives the 16-hour pre-license training, not the Oregon laws/rules/business exam.
- Utah: NASCLA can satisfy the general-contractor experience requirement; Utah's Business & Law requirement has its own listed alternatives.
This is why "NASCLA replaces the state exam" is too broad. It may replace one trade-exam component while leaving a separate state-law step—or, in Oregon and Utah, serve a different function entirely.
Is NASCLA harder than a state exam?
Nobody can honestly answer that across every state and classification. State exams differ in scope, time, references, and candidate background, and the official sources reviewed here do not publish a valid NASCLA-vs-state pass-rate comparison.
Here is what the current NASCLA Commercial General Building exam actually contains, according to the PSI bulletin updated July 7, 2026:
| Subject area | Scored items |
|---|---|
| Procurement and Contracting Requirements | 31 |
| General Requirements | 25 |
| Site Construction | 15 |
| Concrete | 6 |
| Metals | 6 |
| Mechanical and Plumbing Systems | 6 |
| Wood | 5 |
| Thermal and Moisture Protection | 5 |
| Finishes | 5 |
| Masonry | 4 |
| Doors, Windows, and Glazing | 4 |
| Electrical Systems | 3 |
| Total scored | 115 |
There are also 10 unscored pretest questions. The exam allows 330 minutes, and 81 correct is the minimum passing score.
Some practical points from the same bulletin:
- Open book: the exam is open book and uses an approved reference list.
- Code editions: the current bulletin permits the 2021 or 2024 International Building Code for code questions.
- Reference marking: allowed materials may be highlighted, underlined, and permanently tabbed, subject to PSI's current rules.
- Plans: a physical diagram/blueprint packet is provided at the testing center.
A better question than "which is harder?" is: Which exam path matches the license you actually need, and which reference set are you prepared to navigate under time pressure?
What NASCLA costs
For candidates applying directly through NASCLA and scheduling the commercial exam with PSI, the current published fees are:
| Fee | Amount | Source |
|---|---|---|
| NASCLA application | $65 | NASCLA FAQ |
| PSI exam fee | $130 | PSI NASCLA bulletin |
| Transcript to each regulatory agency | $45 | NASCLA FAQ |
Worked example: $65 + $130 = $195 to apply and sit once. Add $45 per agency to send a transcript.
| Agencies receiving a transcript | NASCLA-side total |
|---|---|
| 1 | $240 |
| 2 | $285 |
| 3 | $330 |
These totals exclude state application, license, business/law, bonding, insurance, fingerprinting, education, and other state-specific costs. They also assume one paid PSI sitting.
How long do NASCLA results stay usable?
NASCLA says your exam results do not expire, but a purchased transcript is available for the receiving regulatory agency to view for two years.
That does not mean every state will accept an old NASCLA result indefinitely. Participating agencies can impose their own timing rules. Current examples include:
| Agency | Current timing rule found |
|---|---|
| Arizona ROC | NASCLA exam date must be within the past 2 years |
| North Carolina | NASCLA says within 2 years; verify the exact classification with NCLBGC |
| South Carolina Contractors' Licensing Board | NASCLA score must be within 3 years |
| South Carolina Residential Builders Commission | NASCLA exam must have been passed within 3 years |
| West Virginia | NASCLA scores/transcripts from before September 1, 2013 are not accepted |
If you're planning a multi-state rollout over several years, check the shortest state-specific acceptance window before deciding when to send applications.
Before you pay: the 4-check rule
Run these four checks before you pay for either exam:
- Name the exact licensing agency. Some states have more than one contractor board. Alabama and South Carolina each have two agencies on NASCLA's commercial list.
- Name the exact license classification. Use the board's classification name or code, not a generic label like "GC."
- Confirm what NASCLA actually does for that classification. Does the agency administer it as the trade exam, accept it as a trade-exam waiver, use it for another requirement, or require the state route?
- List what's left. Business/law or rules exam, experience, financial statement, bond, insurance, application, fingerprints, fees, and any NASCLA-score time limit that applies.
If all four line up, register for the route that fits your actual licensing plan. If the board's site leaves the rule unclear or conflicts with NASCLA's listing, confirm with the licensing agency before paying.
Three examples
You plan to license in several participating jurisdictions
You want commercial/general-building licenses in several states and have verified that each target agency accepts the NASCLA result for your classifications. NASCLA is the logical trade-exam route to investigate first because one passing result can reduce duplicate trade testing.
You need one state only
You are focused on one jurisdiction, and its state-specific exam directly matches your classification. The state route may be simpler. NASCLA only adds strategic value if its particular waiver or multi-jurisdiction use matters to your plan.
You need a specialty classification
You need a roofing, plumbing, electrical, mechanical, or other specialty classification. Do not assume the NASCLA Commercial General Building exam covers it. Follow the agency's classification rules, and check NASCLA's separate accredited electrical program only if that is the relevant trade.
How to take the NASCLA route
If the 4-check rule confirms that NASCLA fits your licensing plan:
- Apply through NASCLA's National Examination Database (NED). NASCLA currently charges $65 and says anyone may apply to sit for the exam. Applications are typically processed within 7 business days and are valid for 1 year after approval.
- Schedule with PSI. The current PSI fee is $130. The PSI bulletin says you may schedule online or by phone and may cancel/reschedule without forfeiting the fee if PSI receives the cancellation at least 2 days before the appointment.
- Pass the exam. PSI provides the score report at the test center. NASCLA says PSI may take up to 72 hours to upload results, followed by account-linking time; the total estimate is 5–6 business days.
- Buy a transcript for each agency. NASCLA currently charges $45 per agency, and the agency receives the transcript electronically through NED.
- Complete that jurisdiction's license process. The NASCLA result does not replace the licensing application or any remaining state requirements.
If you took a NASCLA accredited exam through an administering state agency rather than applying through NASCLA, NASCLA says you can send your score report to info@nascla.org so it can review and link the result to your NED account.
