What Is the NASCLA General Contractor Exam and Why Take It?
Thinking about becoming a licensed commercial general contractor across multiple states? The NASCLA exam is a powerful shortcut. In this guide, we will explain what it is, how it works, why it helps your career, and how to prepare without the headaches.
First things first: What does “NASCLA” even mean?
NASCLA stands for the National Association of State Contractors Licensing Agencies. The NASCLA Accredited Commercial General Building Contractor Exam is an open-book test accepted by many state licensing boards. Instead of taking a separate trade exam for each participating state, you can pass one nationally accepted exam and use that score when you apply in those states. That saves time, travel, and a lot of stress.

Why should a contractor take the NASCLA exam?
1) Multi-state mobility
If you work near a state line, travel for projects, or plan to grow, NASCLA lets you qualify in several jurisdictions without repeating a trade exam each time. That means faster approvals when opportunities pop up.
2) Professional credibility
Passing NASCLA signals to owners and GCs that you know the commercial building fundamentals. It can strengthen bids and prequalification packages.
3) Efficiency and savings
One solid study plan, one open-book test, and a reusable transcript. Less duplication, less travel, and fewer exam dates to juggle.
4) Cleaner paper trail
With a NASCLA transcript on file, you can attach it to applications in participating states and focus on the rest of the paperwork and business details.
What materials are used during the exam?
The NASCLA exam is open-book, and one of the key references is the NASCLA Contractors Guide to Business, Law and Project Management, Basic Edition. If you need this specific book, you can grab it from Contractor Exam Preps here: NASCLA Contractors Guide to Business, Law and Project Management, Basic Edition.

What topics does the NASCLA exam cover?
You will see questions related to estimating and plan reading, project management, jobsite safety, contracts, scheduling, and business essentials like payroll, lien law, and insurance. Because it is open-book, preparation is about two things: learning where the answers live, and building speed finding them.
- Business administration basics: organization, accounting, taxes, insurance, bonding
- Contracts and risk: delivery methods, clauses, change orders, claims
- Construction management: scheduling, cost control, quality control, safety
- Plan reading and estimating fundamentals
- Personnel topics: HR basics, compliance, training
Who accepts the NASCLA exam?
Many state boards accept NASCLA for the commercial general building trade portion. You still must meet each state’s individual requirements for business and law, financial responsibility, and application steps. In other words, NASCLA solves the trade exam hurdle, while the rest of the licensing process remains state specific.

How to prepare smart for an open-book exam
Step 1: Gather exactly what you need
Collect the allowed reference books and get them tabbed and indexed so you can flip fast. If you still need the Business, Law and Project Management book, here is that specific edition. For extra organization, consider tab sets and practice materials such as the online simulated practice exams.
Step 2: Build a quick-reference habit
Do not memorize every paragraph. Instead, learn the structure of each chapter and write a few keywords in your tabs. Practice “locate, skim, confirm” until it is automatic.
Step 3: Use targeted exam prep to close gaps
A focused course helps you nail down the highest-frequency topics and question styles. 1 Exam Prep offers a dedicated NASCLA Commercial General Building online exam prep course with flexible options if you prefer lessons, drills, and instructor guidance.
Step 4: Practice under time
Simulated tests help you practice the clock and refine your lookup speed. Try a full-length session each week and review every miss.
Step 5: Tune your test-day plan
- Pack the approved books, a non-programmable calculator, and valid ID
- Bring your tabbed references in a neat stack so you can grab quickly
- Use a two-pass strategy: answer quick wins first, tag “lookups” for round two
- Trust your indexing system and avoid rereading entire pages
Common myths about NASCLA
“It is open-book, so it must be easy.”
Open-book does not mean open-ended. You still need speed, accuracy, and familiarity with where topics live in your books. People who do not practice locating answers usually run out of time.
“If I pass NASCLA, I am licensed everywhere.”
Passing NASCLA does not equal a license. You still apply to a state board, meet financial and experience requirements, and in some states pass a separate business and law exam. If you need help with the paperwork, the NASCLA licensing checklist is a great place to start.
“I can skip studying the business topics.”
Business, law, and project management questions are a big portion of the exam. Practice with resources tied to the Business and Law book, such as online practice questions.
What happens after you pass?
When you pass NASCLA, your result is stored as a transcript you can send to participating state boards. You then complete each state’s application, submit your financials, register your company, and satisfy insurance and bond requirements. If that list sounds like a lot, it is. Good news: help exists. 1 Exam Prep’s application services walk you through credit reports, fingerprints, and required documents so you can focus on running jobs.
How long should you study?
Most candidates plan 4 to 8 weeks, depending on experience and schedule. If you are already comfortable with project management and commercial building topics, you may move faster. If you are new to plan reading or estimating, add time for fundamentals. A structured study course can help you stay on track and learn the best search strategies for an open-book exam.
Quick starter plan you can follow this week
- Get your references and add tabs to chapter openings, key tables, and formulas. If you still need the Business and Law book, choose the Basic NASCLA edition.
- Do 25 practice questions a day, then review each explanation. Try these simulated practice exams for realistic timing.
- Watch a short overview to tie it together, like this NASCLA video.
- Schedule your course blocks for the next two weeks using a structured online prep course.
NASCLA vs. state-specific trade exams
Here is the simple way to look at it: NASCLA is ideal if you want flexibility to compete in multiple states or plan to expand. If you know you will only work in a single state forever, a state-specific exam may be fine. Many contractors start with NASCLA for mobility and then add individual state requirements as their business grows.
Whatever path you choose, solid exam prep, clear scheduling, and a tidy application file will keep you moving forward.
Bottom line: Why take the NASCLA exam?
- It streamlines your path to work across state lines
- It proves commercial building competency to clients and partners
- It reduces duplicate testing, saving time and money
- It pairs well with guided licensing support so nothing falls through the cracks

Conclusion: Your road map to NASCLA success
If you are serious about building a bigger future as a commercial contractor, the NASCLA Accredited Commercial General Building Contractor Exam is one of the smartest moves you can make. Think of it like building a sturdy platform. Instead of stacking separate ladders for each state, you set one strong base you can reuse. That saves you time, money, and energy. It also shows clients and partners that you understand core commercial concepts and can find answers quickly under pressure. In a competitive market, that kind of signal matters.
We covered what NASCLA is, why states accept it, and how it fits into licensing. Passing NASCLA does not hand you a license. It gives you a transferable trade exam result that many boards recognize. After that, you still complete each state’s application, meet financial rules, and sometimes take a business and law exam. That might sound like a lot of steps, but they are manageable with a plan and the right tools. If you want help with the paperwork, 1 Exam Prep’s application services can guide you through the sequence so nothing gets missed.
Preparation for an open-book test looks different than a typical memorization grind. Your mission is to learn the layout of your references, practice fast lookups, and develop calm habits under time. Start by getting the approved books organized with tabs and short notes. The NASCLA Contractors Guide to Business, Law and Project Management, Basic Edition is a core reference. If you still need it, the exact book is here at Contractor Exam Preps: Business, Law and Project Management, Basic Edition. Add targeted drills so your eyes learn where chapters live, and your hands learn to flip without fumbling.
Next, train your timing. A solid way to do that is with simulated exams that mirror the real clock and question mix. Short, daily practice beats one giant cram session. You will make mistakes. That is good. Each mistake teaches you where to improve your tabs, your scanning pattern, or your chapter notes. If you want structured lessons with instructor guidance, 1 Exam Prep’s online NASCLA course is built for this exact exam and keeps you on track.
On test day, keep it simple. Bring the allowed books, your ID, and a clear two-pass plan. Answer the quick wins first, mark the deeper lookups for round two, and trust your indexing system. Do not lose minutes rereading whole pages when a table or heading can point you to the right spot in seconds. Your goal is steady progress and clean choices. When you finish, you will have a result you can reuse across participating states as your business grows.
Big picture, NASCLA gives you options. Maybe you want to cross state lines for a school renovation. Maybe a client wants you to follow them to a neighboring state. Maybe you are just building a stronger resume. Whatever your reason, one exam can support many paths. Pair that with a tidy application file and a little help where you need it, and you will move faster with fewer surprises.
So here is your next step. Set your timeline, gather your references, and practice the way you plan to perform. Use simple tools, work in small chunks, and keep your eyes on the goal. With a clear plan and consistent effort, you will be ready to walk into test day confident and walk out with a result that opens doors.
