NASCLA exam vs a state trade exam: which to take
The NASCLA Commercial General Building exam is a national trade exam that participating states accept in place of their own commercial or general building trade exam. Pass it once and you can send the result to each accepting state where you want a license, instead of sitting each state's trade exam. Each state's application and business and law exam still apply.
If you want a commercial or general building license, the trade exam is the hurdle in the middle: after the application, alongside the business and law exam. In some states you can meet it with the NASCLA Accredited Examination for Commercial General Building Contractors instead of the state's own trade exam. This page sets out what that swap does and does not do, so you can choose with your state agency's answer in hand.
What the NASCLA exam replaces
PSI's Candidate Information Bulletin (updated 7 Jul 2026) describes the NASCLA exam as a streamlined option for the trade portion of the contractor examination. Agencies that accept it take a NASCLA pass in place of their own trade exam for the general commercial building classification or a similar one.
It replaces nothing else. The bulletin says candidates still follow each state agency's application and take a business and law exam, among other requirements. NASCLA's own page says the same: you must follow all state agency application policies and procedures to become licensed.

When the NASCLA exam tends to make sense
- You expect to work in more than one participating state. One pass can be sent to several agencies as NED transcripts, instead of sitting a separate trade exam in each.
- Your state offers a choice. NASCLA's agency page says some agencies let you take either their own trade exam or the NASCLA exam. Its map, read 7 Nov 2026, shades Alabama, Arizona, Arkansas, Georgia, Mississippi, South Carolina, Tennessee and the U.S. Virgin Islands that way, though Alabama and South Carolina each have one agency of each kind. Ask your agency which applies to you.
- You want to study one known reference list. The bulletin lists the 24 references and the edition rules in one place.
When a state's own exam may suit you better
- You only need one state and it does not accept the NASCLA exam, or does not accept it for your license class. Then there is no choice to make.
- Your state's own exam fits work you already know better. Compare the two reference lists and content outlines before you decide.
- Timing. The NASCLA route adds an application step with NASCLA before you can book. Ask how long your state's own route takes.
These are things to weigh, not rules. Only the state agency can tell you which exams it accepts for which license.
Questions to ask your state agency
- Do you accept the NASCLA Commercial General Building exam for the license class I want?
- Do you also offer your own trade exam for it, and is either one preferred?
- What else do you require: application, business and law exam, financial statements, insurance, bonds, experience?
- How do you want the NED transcript sent, and does it need to arrive before or with my application?

No. It stands in for the trade exam only. The state's business and law exam, where it has one, and its application are separate.
Why take the NASCLA exam instead of a state trade exam?
One pass can be used in every accepting state where you want a license. You send it to each agency as a transcript from NASCLA's National Examination Database (NED).
