Free practice test — 12 questions with full explanations
Original CraftPATH practice questions. These are not real exam questions. Every answer includes the reasoning, why each wrong option fails, the code area it comes from, and the misconception it targets.
Question 1. Contractor licensing in Nevada is administered by:
Nevada Law, NRS 624 and Licensing Scope · Easy · Objective: Identify the Nevada licensing authority.
- A. The Nevada State Contractors Board (correct)
- B. Each county building department
- C. The Nevada Department of Motor Vehicles
- D. The Nevada Secretary of State
Correct answer: A. The Nevada State Contractors Board
Why this is right: The Nevada State Contractors Board licenses and regulates contractors statewide under NRS Chapter 624, including classification, examination, bonding and discipline.
Why the other options are wrong:
- B. Each county building department — County building departments issue permits and inspect but do not license contractors.
- C. The Nevada Department of Motor Vehicles — The DMV has no role in contractor licensure.
- D. The Nevada Secretary of State — The Secretary of State registers business entities, which is separate from a contractor license.
Where this shows up on the job: You will register your entity with the Secretary of State and obtain local business licenses, but the contractor license itself comes from the NSCB.
Code reference: Nevada Revised Statutes Chapter 624
Common misconception: Assuming a state business registration allows you to contract.
Question 2. A Nevada contractor's monetary limit determines:
Nevada Law, NRS 624 and Licensing Scope · Hard · Objective: Apply the license monetary limit.
- A. The maximum amount the contractor may spend on tools each year
- B. The maximum contract amount, including labor and materials, the contractor may undertake on a single project (correct)
- C. The value of the surety bond only
- D. How many employees the contractor may hire
Correct answer: B. The maximum contract amount, including labor and materials, the contractor may undertake on a single project
Why this is right: Nevada sets a monetary limit from the applicant's reviewed financial statement, and it caps the total value of a single project the licensee may contract for. Exceeding it is grounds for discipline.
Why the other options are wrong:
- A. The maximum amount the contractor may spend on tools each year — Tool purchases are unrelated to the limit.
- C. The value of the surety bond only — The bond is a separate requirement, though both come from the board's financial review.
- D. How many employees the contractor may hire — Employee count is not limited by the license.
Where this shows up on the job: Contractors who land a job above their limit apply to the board to raise it rather than splitting the contract, which is itself a violation.
Code reference: NRS 624 and NAC 624 financial responsibility provisions
Common misconception: Splitting one project into multiple contracts to stay under the limit.
Question 3. A Nevada licensed company must have a qualified individual who:
Nevada Law, NRS 624 and Licensing Scope · Medium · Objective: Understand the qualified individual requirement.
- A. Owns at least 51 percent of the company
- B. Passed the required examinations and actively exercises supervision and control of the licensed operations (correct)
- C. Lives within 50 miles of every jobsite
- D. Holds a real estate license
Correct answer: B. Passed the required examinations and actively exercises supervision and control of the licensed operations
Why this is right: The qualifier is the person who passed the trade and business and law examinations and who must actually direct the construction operations, not merely lend a name to the license.
Why the other options are wrong:
- A. Owns at least 51 percent of the company — There is no fixed ownership percentage requirement for a qualifier.
- C. Lives within 50 miles of every jobsite — No such residency-to-jobsite rule exists.
- D. Holds a real estate license — Real estate licensure is unrelated.
Where this shows up on the job: Renting a qualifier's license without real supervision is one of the violations the board pursues most aggressively.
Code reference: NRS 624 qualified employee provisions
Common misconception: Believing a qualifier can be a paid name on paper.
Question 4. A job costs 80,000 dollars and the contractor wants a 20 percent gross margin. The contract price should be approximately:
Business Management, Estimating and Contracts · Hard · Objective: Distinguish markup from margin.
- A. 96,000 dollars
- B. 100,000 dollars (correct)
- C. 88,000 dollars
- D. 116,000 dollars
Correct answer: B. 100,000 dollars
Why this is right: Margin is measured against the selling price, so the price is cost divided by one minus the margin: 80,000 divided by 0.80 equals 100,000 dollars.
Why the other options are wrong:
- A. 96,000 dollars — 96,000 is cost plus a 20 percent markup, which yields only about a 16.7 percent margin.
- C. 88,000 dollars — 88,000 is a 10 percent markup and far short of the target.
- D. 116,000 dollars — 116,000 corresponds to a 45 percent markup, well above the target.
Where this shows up on the job: Confusing markup with margin is the single most common reason small residential builders underprice work and run out of cash mid-project.
Code reference: Construction business management fundamentals
Common misconception: Adding the margin percentage directly to cost.
Question 5. The correct way to handle additional work requested by a homeowner mid-project is to:
Business Management, Estimating and Contracts · Medium · Objective: Handle change orders correctly.
- A. Perform it and add the cost to the final invoice
- B. Issue a written change order describing the work, price and schedule impact, signed before proceeding (correct)
- C. Absorb the cost to keep the client happy
- D. Verbally confirm it with the homeowner and note it in your phone
Correct answer: B. Issue a written change order describing the work, price and schedule impact, signed before proceeding
Why this is right: A signed written change order documenting scope, price and schedule impact protects payment rights and is what the board and the courts look for when a residential dispute arises.
Why the other options are wrong:
- A. Perform it and add the cost to the final invoice — Surprise charges on a final invoice are the leading source of homeowner complaints.
- C. Absorb the cost to keep the client happy — Absorbing scope creep destroys margin and sets a precedent.
- D. Verbally confirm it with the homeowner and note it in your phone — A verbal agreement is difficult to enforce and does not satisfy residential contract documentation expectations.
Where this shows up on the job: Most residential complaints filed with the board involve undocumented extras and disputed final balances.
Code reference: NRS 624 residential contract provisions
Common misconception: Treating small extras as too minor to document.
Question 6. Building on collapsible or expansive soils common in parts of Nevada primarily requires:
Site Work, Foundations and Desert Soils · Hard · Objective: Recognize problem soils in Nevada.
- A. Thicker exterior paint
- B. A geotechnical investigation with an engineered foundation and moisture control strategy (correct)
- C. Deeper roof overhangs
- D. Larger windows to reduce load
Correct answer: B. A geotechnical investigation with an engineered foundation and moisture control strategy
Why this is right: Collapsible and expansive soils move with moisture change. The remedy is a geotechnical report driving an engineered foundation design plus grading and drainage that keeps moisture away from the soil beneath the structure.
Why the other options are wrong:
- A. Thicker exterior paint — Paint has no bearing on soil behavior.
- C. Deeper roof overhangs — Overhangs help walls, not the bearing soil.
- D. Larger windows to reduce load — Window size does not change foundation loading in a meaningful way.
Where this shows up on the job: Post-tensioned slabs and over-excavation with engineered fill are common Nevada answers, and both start with the soils report.
Code reference: Adopted building code foundation chapter and geotechnical investigation requirements
Common misconception: Using a standard footing detail on every lot in a subdivision.
Question 7. Finish grade around a residential foundation must:
Site Work, Foundations and Desert Soils · Medium · Objective: Grade for drainage.
- A. Be level with the top of the slab
- B. Slope away from the building for the required distance to move surface water off the foundation (correct)
- C. Slope toward the building so landscaping is watered
- D. Match the neighboring lot exactly
Correct answer: B. Slope away from the building for the required distance to move surface water off the foundation
Why this is right: Positive drainage away from the structure is required so surface and irrigation water does not saturate bearing soil or reach the foundation. In desert soils, uncontrolled water is the primary cause of movement.
Why the other options are wrong:
- A. Be level with the top of the slab — Grade at slab level defeats the required drop and traps water at the wall.
- C. Slope toward the building so landscaping is watered — Directing water toward the building is the failure mode the code prevents.
- D. Match the neighboring lot exactly — Neighboring grade does not establish compliance for your lot.
Where this shows up on the job: Homeowner irrigation installed against the foundation after closeout undoes the original grading and causes callbacks.
Code reference: Adopted building code site grading and drainage provisions
Common misconception: Assuming a dry climate makes drainage detailing optional.
Question 8. A braced or shear wall panel resists lateral load only if:
Framing, Structural Loads and Wind · Hard · Objective: Understand shear wall load paths.
- A. It is painted and finished
- B. A continuous load path carries the force from roof to wall sheathing to hold-downs and into the foundation (correct)
- C. It is at least 12 feet long
- D. It contains no electrical boxes
Correct answer: B. A continuous load path carries the force from roof to wall sheathing to hold-downs and into the foundation
Why this is right: Lateral resistance depends on the complete load path: diaphragm to shear wall, correct sheathing nailing, hold-downs at panel ends, and anchorage into the foundation. Break any link and the panel does not perform.
Why the other options are wrong:
- A. It is painted and finished — Finish materials contribute nothing to the rated capacity.
- C. It is at least 12 feet long — Panel length requirements vary with the bracing method, and length alone is not sufficient.
- D. It contains no electrical boxes — Electrical boxes are normal and do not void the panel.
Where this shows up on the job: Missing or mis-set hold-down anchors are one of the most common framing inspection failures.
Code reference: Adopted residential code wall bracing and shear wall provisions
Common misconception: Assuming heavy nailing alone makes a shear wall.
Question 9. A roof truss that arrives with a broken web member should be:
Framing, Structural Loads and Wind · Medium · Objective: Handle engineered trusses correctly.
- A. Reinforced by nailing scrap lumber over the break
- B. Installed and covered because the sheathing will carry the load
- C. Repaired only with a written repair detail from the truss engineer, or replaced (correct)
- D. Cut out and framed conventionally on site
Correct answer: C. Repaired only with a written repair detail from the truss engineer, or replaced
Why this is right: Trusses are engineered assemblies. Any modification or repair requires a detail from the truss design engineer, otherwise the assembly no longer matches the sealed design.
Why the other options are wrong:
- A. Reinforced by nailing scrap lumber over the break — Field-improvised scabbing has no engineering basis and will not pass inspection.
- B. Installed and covered because the sheathing will carry the load — Sheathing is not a substitute for a truss member.
- D. Cut out and framed conventionally on site — Substituting stick framing on the fly changes the structural system without design review.
Where this shows up on the job: Truss manufacturers issue repair details routinely; asking for one costs a day, while a hidden field repair can cost a roof.
Code reference: Adopted residential code truss provisions and truss design drawings
Common misconception: Treating a truss like ordinary dimensional lumber.
Question 10. Window flashing performs correctly when:
Building Envelope, Roofing and Energy · Medium · Objective: Install flashing in the correct sequence.
- A. Every joint is sealed with caulk on the exterior face
- B. Each layer laps over the one below in shingle fashion so water drains to the exterior (correct)
- C. The head flashing is installed under the weather-resistive barrier's lower course
- D. The sill is sealed continuously across the bottom with no drainage path
Correct answer: B. Each layer laps over the one below in shingle fashion so water drains to the exterior
Why this is right: Flashing works by gravity and lapping. Each upper layer must lap over the layer below so water is directed out over the weather-resistive barrier rather than behind it.
Why the other options are wrong:
- A. Every joint is sealed with caulk on the exterior face — Caulk is a supplement with a limited service life, not the drainage plane.
- C. The head flashing is installed under the weather-resistive barrier's lower course — Head flashing tucked under a lower course reverses the lap and channels water inside.
- D. The sill is sealed continuously across the bottom with no drainage path — A fully sealed sill traps any water that does get in with nowhere to drain.
Where this shows up on the job: Reverse-lapped head flashing is a leading cause of window leaks that appear years after construction.
Code reference: Adopted building code flashing and weather-resistive barrier provisions
Common misconception: Relying on sealant instead of correct lapping.
Question 11. In southern Nevada's climate, the envelope measure with the largest cooling impact is typically:
Building Envelope, Roofing and Energy · Medium · Objective: Apply energy provisions in a high solar gain climate.
- A. Adding interior trim
- B. Controlling solar heat gain through glazing plus duct and envelope air sealing (correct)
- C. Painting the interior walls a light color
- D. Increasing the number of exterior doors
Correct answer: B. Controlling solar heat gain through glazing plus duct and envelope air sealing
Why this is right: In a hot, high solar gain climate, glazing solar heat gain coefficient and leakage in the envelope and ducts drive cooling load more than most other single measures.
Why the other options are wrong:
- A. Adding interior trim — Trim has no thermal effect.
- C. Painting the interior walls a light color — Interior color affects lighting, not cooling load meaningfully.
- D. Increasing the number of exterior doors — More doors add leakage and heat transfer rather than reducing load.
Where this shows up on the job: Ducts run through a Las Vegas attic can see extreme temperatures, which is why sealing and insulating them pays back quickly.
Code reference: Adopted energy code envelope and duct provisions
Common misconception: Treating insulation R-value as the only energy measure that matters.
Question 12. A Nevada residential jobsite working through July must primarily:
Jobsite Safety and Heat Illness Prevention · Easy · Objective: Plan for extreme heat.
- A. Start later in the day so crews avoid the morning
- B. Provide potable water, shade or cooling, rest breaks, acclimatization and heat illness training (correct)
- C. Require long sleeves and nothing else
- D. Rely on workers to self-manage hydration
Correct answer: B. Provide potable water, shade or cooling, rest breaks, acclimatization and heat illness training
Why this is right: Heat illness prevention is built on water, shade and rest, plus acclimatizing new or returning workers and training everyone to recognize symptoms and respond.
Why the other options are wrong:
- A. Start later in the day so crews avoid the morning — Shifting later in the day moves work into the hottest hours.
- C. Require long sleeves and nothing else — Clothing alone does not address hydration, rest or emergency response.
- D. Rely on workers to self-manage hydration — Self-management is not a program and leaves new workers most at risk.
Where this shows up on the job: New hires in their first days on a Nevada summer site are the highest-risk group, which is why acclimatization is explicit.
Code reference: 29 CFR 1926 general duty and Nevada OSHA heat illness guidance
Common misconception: Assuming experienced crews do not need a heat program.
How to study for the Nevada residential contractor exam
Study the law exam as seriously as the trade exam
Nevada's business and law examination covers NRS 624, monetary limits, bonding, the qualified individual requirement, residential contract rules and disciplinary grounds. Candidates who focus only on construction often fail this half.
Know your classification scope
B-2 Residential and Small Commercial has defined limits, and specialty C classifications cover individual trades. Exam questions test whether a given scope of work is inside or outside your classification.
Master the money math
Markup versus margin, overhead allocation, progress payments and retention appear repeatedly. Work the arithmetic until dividing by one minus the margin is automatic.
Learn desert-specific construction
Collapsible and expansive soils, positive drainage, high solar gain glazing, duct losses in scorching attics, and wind bracing are the practical topics that separate Nevada from a generic residential exam.
Run a six-week plan
Week one: NRS 624, classifications and monetary limits. Week two: business management, estimating and contracts. Week three: site work and foundations. Week four: framing and lateral bracing. Week five: envelope, roofing and energy. Week six: full-length timed sets under exam conditions.
Frequently asked questions
Which Nevada classification do residential builders need?
Most residential builders pursue the B-2 Residential and Small Commercial classification. Individual trades are covered by specialty C classifications, and the board defines the scope of each.
What is a monetary limit?
Nevada assigns each license a monetary limit based on the applicant's reviewed financial statement. It caps the total value of a single contract the licensee may undertake, and it can be raised by application to the board.
How many exams do I have to pass?
Typically two: a trade examination for your classification and a business and law examination covering NRS 624 and construction management. Confirm the current requirements with the board.
How much experience do I need before I can test?
Experience requirements are set by the board and revised periodically, so we leave those figures pending. Confirm the current requirement with the NSCB before applying.
Is a Nevada contractor license valid statewide?
Yes. The NSCB license is recognized statewide, though local jurisdictions still issue permits, inspect work, and require local business licensing.
Are these real Nevada exam questions?
No. Every question here is original CraftPATH material written to the same subject areas the exam covers. We do not reproduce live examination content.
How long should I study?
Most candidates need six to ten weeks of focused review, split roughly evenly between the business and law material and the trade content.
