The NASCLA Accredited Examination for Commercial General Building Contractors is useful for contractors who expect to apply in more than one participating jurisdiction. But it is often described incorrectly. It is a portable trade examination result, not a business-and-law exam, a license, or automatic reciprocity.

This guide reflects NASCLA’s participating-agency list and the PSI candidate bulletin available on September 21, 2026. Always confirm the classification match with the destination licensing agency before paying or scheduling.

What the NASCLA exam does

NASCLA is a nonprofit association of contractor-licensing agencies. Its Commercial General Building examination gives participating agencies a common way to evaluate general-building trade knowledge. An agency that accepts the exam may use the passing result in place of its own corresponding trade examination.

That distinction matters. NASCLA’s own FAQ says the exam is not a national license or certification. Passing it does not authorize contracting anywhere. You must apply for a license in each jurisdiction and satisfy that agency’s classification, experience, financial, insurance, bond, background-check, and business-law requirements.

Current exam format and cost

The current PSI bulletin describes a computer-delivered, open-book commercial general building exam with:

  • 115 scored questions plus 10 unscored pretest questions
  • 330 minutes of testing time
  • 81 correct answers required to pass
  • $65 NASCLA application fee and a separate $130 PSI examination fee
  • Three attempts during the one-year eligibility period

The exam is broader than one business-law book. Its outline covers general requirements, site construction, concrete, masonry, metals, wood, building envelope work, finishes, building systems, and procurement/contracting. The approved reference list contains numerous code and construction-management books. Use the current PSI bulletin rather than an old prep provider’s list; editions and permitted references can change.

Which agencies accept it?

NASCLA’s current page lists 20 accepting licensing agencies across 18 jurisdictions. Alabama and South Carolina each have two participating boards. The jurisdictions are:

  • Alabama
  • Arizona
  • Arkansas
  • California
  • Florida
  • Georgia
  • Louisiana
  • Mississippi
  • Nevada
  • New Mexico
  • North Carolina
  • Oregon
  • South Carolina
  • Tennessee
  • Utah
  • U.S. Virgin Islands
  • Virginia
  • West Virginia

Acceptance is classification-specific. It does not mean every board in that jurisdiction, every contractor classification, or every residential license accepts the result. California, for example, now appears on NASCLA’s accepting-agency list, but applicants still need to meet CSLB’s waiver and classification rules. Check the agency entry linked from NASCLA’s live list before relying on the waiver.

What it normally does not waive

  • The license application: you still apply to each board separately.
  • State business and law: the PSI bulletin expressly warns that a participating agency may still require its business-law examination.
  • Experience and classification review: the agency decides whether your background and requested scope qualify.
  • Financial, bond, and insurance requirements: these remain jurisdiction-specific.
  • Other trade exams: electrical, plumbing, HVAC, roofing, or specialty classifications follow their own rules.

How to use the result

  1. Start with the destination agency. Confirm that it accepts this exact exam for the license classification you want and ask what other exams remain.
  2. Apply through NASCLA’s National Examination Database. NASCLA says applications are normally processed within seven business days; an approval is valid for one year.
  3. Use the current bulletin. Build your reference set from PSI’s current list and follow its rules on tabs, notes, identification, and scheduling.
  4. Pass within the eligibility window. NASCLA allows up to three attempts in that year. If you do not pass, you must wait until the eligibility period ends before reapplying.
  5. Send an official transcript. NASCLA currently charges $45 for each transcript sent electronically to a regulatory agency. NASCLA says exam results do not expire, while a purchased transcript remains viewable by the agency for two years.
  6. Complete the state application. Do not bid or contract until the destination authority has actually issued the required license.

Who benefits most?

The exam is most attractive when two or more target agencies have already confirmed that it will replace their general-building trade exam. It can also be sensible for a contractor who expects future multi-state expansion. For a one-state applicant, compare the NASCLA route with that state’s ordinary exam route; the portable result may not justify the extra application and transcript costs.

Do not choose it based only on a marketing claim that it works in “20-plus states.” Count the specific agencies and classifications that match your plan. A reusable exam score is valuable, but the license remains local to each jurisdiction.
