Important North Carolina rule: NASCLA is an accepted examination credential, not a North Carolina contractor license. The North Carolina Licensing Board accepts the NASCLA Commercial General Building examination for the Building classification, but applicants must still complete the North Carolina licensing process and the required North Carolina Business and Law examination.
The NASCLA Accredited Examination for Commercial General Building Contractors is a standardized commercial construction examination accepted by participating contractor licensing agencies across the United States.
North Carolina accepts the NASCLA examination as an approved trade-exam path for the Building Contractor classification. That classification covers a broad range of commercial, industrial, institutional and residential building construction.
The NASCLA exam does not create a national contractor license. Passing it gives you an examination credential that can be sent through the NASCLA National Examination Database to participating licensing agencies.
NASCLA exam: satisfies an accepted trade-examination path for the North Carolina Building classification.
North Carolina license: is issued separately by the North Carolina Licensing Board for General Contractors after the application, qualifier, financial and other state requirements are satisfied.
Business and Law: North Carolina applicants using NASCLA must also complete the North Carolina Business and Law examination.
The North Carolina NASCLA Commercial General Building Contractor Online Exam Prep Course is designed to organize the large NASCLA syllabus and help candidates build faster open-book reference skills.
The NASCLA examination comes first. North Carolina then applies its own licensing, Business and Law, qualifier and financial requirements.

The current NASCLA Commercial General Building examination has 115 scored questions. You need at least 81 correct scored answers to reach the 70 percent passing requirement.
The exam also includes 10 additional unscored pretest questions. Those questions are mixed into the examination and are not identified, so candidates may see 125 total questions even though only 115 are scored.
You receive 330 minutes, or five hours and thirty minutes, for the entire examination. With 125 questions presented, that works out to roughly two minutes and 38 seconds per question.
The largest subject is Procurement and Contracting Requirements with 31 scored questions. General Requirements contains 25, and Site Construction contains 15. Those three areas alone account for 71 of the 115 scored questions.
NASCLA is broad. A contractor may know concrete extremely well and still run into questions about accessibility, steel joists, stormwater, gypsum, OSHA, roofing or project management.
Start with Procurement and Contracting. It is the largest current category with 31 scored questions.
Give General Requirements major study time. This section adds another 25 questions.
Study Site Construction carefully. Fifteen questions cover another major part of the test.
Practice with the books. The test is open book, but a large reference library is only useful when you already know which book belongs to the question.
NASCLA candidates should be ready for practical construction calculations involving quantities, areas, volumes, concrete, excavation, materials, project costs and plans.
Simplified NASCLA general contractor exam prep illustration for plans, estimating, site construction and code navigation.
Use a simple process. Identify what the problem asks for, write down the dimensions or quantities, select the correct formula or table and then confirm the result against the plans or reference material.
Complete the NASCLA credential first, then finish the North Carolina-specific licensing requirements.
Make sure the Building classification matches the construction work your company intends to perform.
North Carolina directs candidates choosing the NASCLA pathway to complete the NASCLA examination process before applying for the North Carolina general contractor license.
Organize the NASCLA commercial construction references and practice identifying which book controls each subject.
Earn at least 81 correct answers from the 115 scored questions within the 330-minute examination window.
Use the National Examination Database to send your examination credential to the North Carolina Licensing Board.
Select the Building classification and Limited, Intermediate or Unlimited limitation, then satisfy the Board's application and financial requirements.
Prepare for the 40-question, 90-minute state examination covering licensing, liens, bonds, One Call, subcontractor payment and erosion control.
These counts follow the current July 2026 PSI/NASCLA content outline. Bar lengths compare each category with the largest 31-question Procurement and Contracting section.
High-value study fact: Procurement and Contracting, General Requirements and Site Construction combine for 71 of the 115 scored questions. That is about 61.7 percent of the scored exam.
The current July 2026 bulletin uses a large open-book reference library. Always compare your exact editions with the live PSI/NASCLA bulletin before testing.

Passing the NASCLA examination and receiving a North Carolina contractor license are two different things.
NASCLA provides an accepted commercial construction examination credential. North Carolina decides whether an applicant meets the requirements for the state's Building Contractor license.
NASCLA: tests commercial general building knowledge and can replace the state-specific trade examination for an accepted classification.
North Carolina: issues the contractor license after reviewing the application, qualifier, financial requirements, Business and Law examination and other licensing requirements.
Project threshold: North Carolina generally requires a licensed general contractor when the project cost is $40,000 or more.
The Building classification controls the type of work. The limitation controls the maximum value of a single project.
| Limitation | Project Limit | Current Financial Requirement |
|---|---|---|
| Limited | Up to $750,000 on a single project | At least $17,000 working capital or $80,000 net worth, or qualifying $175,000 surety bond |
| Intermediate | Up to $1,500,000 on a single project | At least $75,000 working capital, or qualifying $500,000 surety bond |
| Unlimited | No restriction on single-project value | At least $150,000 working capital, or qualifying $1,000,000 surety bond |
Break the giant NASCLA reference library into manageable construction subjects instead of trying to learn everything on one heroic Saturday.
The NASCLA exam is challenging because it covers a huge range of commercial construction knowledge. It is not just a building-code test and it is not just a business exam.
A candidate can move from concrete to accessibility, then to steel joists, then OSHA, then contracts, then mechanical systems. The books on your desk may start looking like a small library branch.
The biggest scoring opportunities are Procurement and Contracting, General Requirements and Site Construction. Strong candidates study those heavily while still protecting points in the smaller trade sections.
Reference speed matters just as much as reference ownership. Owning twenty books is impressive. Finding the correct answer in one of them before your coffee gets cold is more useful.
North Carolina Business and Law: NASCLA applicants should also prepare separately for the state Business and Law examination. The North Carolina Business and Law Contractor Exam Complete Pass Package focuses on the state-specific portion.

The NASCLA credential gives North Carolina Building Contractor candidates an alternative to the state-specific Building trade exam.
• 115 scored questions
• 10 additional unscored pretest questions
• 330 minutes

Passing NASCLA gives you an exam credential, not an automatic license. Finish the North Carolina licensing process before contracting under the Building classification.
