Current NASCLA exam: PSI lists 115 scored questions, 10 unscored pretest questions, 330 minutes, and 81 correct scored answers to pass. The exam is open book and accepts the current approved reference list, including either the 2021 or 2024 International Building Code. Review the current NASCLA/PSI bulletin and Arkansas contractor licensing guidance before testing.
What Is the Arkansas NASCLA Commercial General Building Contractor Path?
Arkansas participates in the NASCLA Accredited Examination Program. Contractors using the commercial building examination route may use a passing NASCLA Commercial General Building Contractor result toward the trade-examination side of licensing, but the NASCLA exam is not an Arkansas contractor license by itself.
Short answer: the current NASCLA exam contains 115 scored questions plus 10 unscored pretest questions, allows 330 minutes, and requires 81 correct scored answers. Arkansas Business and Law remains a separate state exam when required.
Arkansas Building is a major classification. Current Arkansas rules require at least five years of appropriate experience or passing the appropriate examination for major classifications. That is why a strong contractor exam prep page must separate experience qualification, the NASCLA trade exam, Arkansas Business and Law, and the final contractor license application.
This guide combines current NASCLA testing information, Arkansas licensing requirements, Business and Law, approved reference guidance, open-book strategy, commercial construction topic weights, and structured contractor exam prep without pricing.

Arkansas NASCLA Commercial Contractor Exam Breakdown
The commercial building path combines a national NASCLA trade exam with Arkansas-specific licensing and Business and Law requirements.
NASCLA Commercial Exam115 scored questions + 10 pretest | 330 minutes | 81 correct to pass
Arkansas Business and Law50 questions | 120 minutes | 35 correct to pass
NASCLA FormatOpen book with approved references brought by the candidate
Arkansas Testing ProviderPSI
Licensing AuthorityArkansas Contractors Licensing Board
IBC Options2021 or 2024 International Building Code under the current bulletin
NASCLA EligibilityOne year from approval | maximum three exam attempts
Arkansas Building QualificationFive years appropriate experience or passing the appropriate examination
Commercial ThresholdGenerally 50,000 dollars or more in labor and materials for covered commercial work
Keep the exams separate. NASCLA is the commercial trade exam. Arkansas Business and Law is the state-specific business, licensing, legal, and management exam.
NASCLA is open book. Candidates bring the approved references.
Business and Law is also reference-based. It uses the current Arkansas NASCLA Contractors Guide to Business, Law and Project Management.
Passing NASCLA does not issue the Arkansas license. The contractor application, classification, financial, bonding, and state requirements still apply.
NASCLA Book Navigation, Construction Knowledge and Open-Book Problem Solving
The NASCLA contractor exam rewards candidates who can identify the construction subject, choose the correct reference, locate the controlling code or construction rule, and answer under a long but demanding time limit.
Simplified study illustration. Use the current official NASCLA reference list for actual exam preparation.
Train every practice question as a lookup sequence: identify the subject, choose the most likely reference, use the index or permanent tab, confirm the controlling rule, answer, and move on.
- Procurement and Contracting: 31 questions.
- General Requirements: 25 questions.
- Site Construction: 15 questions.
- Concrete / Metals / Mechanical and Plumbing: 6 questions each.
- Wood / Thermal and Moisture / Finishes: 5 questions each.
| Skill | What to Practice | Common Mistake |
|---|---|---|
| Reference selection | Identify which book owns the question before opening anything | Searching several books for a question that belongs to one obvious reference |
| IBC navigation | Chapters, tables, occupancy, construction type, accessibility and code structure | Reading long code sections instead of using index terms and table references |
| Contracts and management | Procurement, project administration, estimating, scheduling and contractor responsibilities | Under-studying the largest exam category |
| Technical construction | Concrete, masonry, metals, wood, roofing, finishes and building systems | Studying facts without learning which book contains them |
| OSHA and safety | Construction hazards, fall protection, excavation, scaffolds and site safety | Looking in a building code when the question belongs in OSHA |
| Time management | Timed blocks, skip-return strategy and long-session stamina | Spending too long proving one difficult answer |
Practice the book path, not only the answer. Record the question topic, correct reference, index term, page or section, and lookup time after every missed contractor exam prep question.

How to Use the NASCLA Books During the Open-Book Exam
Winning open-book contractor habits
- Bring the exact current approved references
- Use compliant permanent tabs before exam day
- Highlight, underline and index references before testing as allowed
- Practice choosing the correct book before searching
- Know the IBC chapter structure and common technical indexes
- Complete timed contractor exam prep with the actual book set
Avoid these exam-prep mistakes
- Using temporary removable tabs
- Bringing loose or attached extra papers
- Assuming every older book edition is still accepted
- Trying to memorize the entire reference library
- Ignoring Procurement, General Requirements and Site Construction
- Spending too long in one book on one difficult question
NASCLA reference rule: candidates are responsible for bringing the approved books. A physical diagram or blueprint packet is provided onsite under the current bulletin, but the reference books themselves are not supplied.
Arkansas Contractor Business and Law Exam
The Arkansas Business and Law exam is separate from NASCLA. The current PSI bulletin lists 50 questions, 120 minutes and a passing requirement of 35 correct answers.
The largest topic is Arkansas Contractor Rules and Regulations with nine questions. Contracts and Agreements, Estimating and Bidding, and Insurance and Bonding each contribute five questions.
Other topics include Business Management, Financial Management, Project Management, Arkansas Lien Laws, Labor Laws and Employment Regulations, Tax Laws, Environmental Laws and Regulations, and OSHA Recordkeeping and Reporting.
NASCLA Exam vs Arkansas Business and Law vs Arkansas Contractor License
These are related parts of the commercial contractor path, but they are not interchangeable.
| Path | Focus | Important Note |
|---|---|---|
| NASCLA Commercial General Building Exam | National commercial building trade knowledge and open-book reference use | 115 scored questions + 10 pretest | 330 minutes |
| Arkansas Business and Law | Arkansas contractor rules, contracts, finance, management, lien law and state requirements | Separate 50-question Arkansas exam |
| Building Classification Qualification | Appropriate experience or appropriate examination | Major classification currently uses a five-year experience standard or the exam route |
| Arkansas Commercial Contractor License | Actual state authority to contract under the approved classification | Passing NASCLA alone does not issue the license |
| Contractor Exam Prep | Reference navigation, topic review, timed practice and exam strategy | Study support, not a state-issued credential |
Confirm the route before testing. Use the current Arkansas application and rules to determine how experience, examination, Business and Law, financial documents, bonding and classification requirements apply to your company.

How Hard Is the NASCLA Commercial General Building Contractor Exam?
The challenge is not only the 115 scored questions. Candidates work through a large reference library, broad commercial construction topics, and a 330-minute testing period while also handling ten unscored pretest questions.
Common avoidable problems include weak book selection, outdated references, poor permanent-tab organization, under-studying the 71 questions concentrated in the top three domains, and spending too long on one lookup. Structured contractor exam prep turns those risks into repeatable reference-navigation habits.

After You Pass the NASCLA Commercial General Building Exam
Passing NASCLA satisfies an examination credential used by participating jurisdictions. It does not automatically issue an Arkansas contractor license.
Arkansas applicants must still satisfy the current state classification, Business and Law, application, financial, bonding, entity, and supporting-document requirements that apply to their license path.
NASCLA maintains a National Examination Database for participating state agencies. Follow the current NASCLA and Arkansas instructions for transmitting and using the examination result.
