NASCLA Exam Flashcards

Q: Does passing NASCLA give me a contractor license?

No. NASCLA is an accredited commercial contractor examination. State agencies decide licensing requirements, so candidates still must satisfy the license application, law exam, insurance, bond, and financial rules for their jurisdiction.

Q: How should I use flashcards for an open-book NASCLA exam?

Use flashcards to learn concepts and vocabulary, then pair them with timed reference lookups. The exam rewards knowing where rules live in the approved books as well as understanding the construction scenario.

Question 1

NASCLA exam format

Accepted Answer

The NASCLA commercial general building contractor exam has 115 questions, a 5.5 hour time limit, and a 70% passing score.

Question 2

Open-book strategy

Accepted Answer

Open-book does not mean slow lookup. Organize references, tab high-use sections, and practice finding rules quickly under time pressure.

Question 3

Procurement and contracting weight

Accepted Answer

Procurement and contracting is the largest NASCLA domain in the local outline, so bidding, contracts, changes, submittals, and closeout deserve priority.

Question 4

General requirements weight

Accepted Answer

General requirements is another major NASCLA domain, covering planning, estimating, project management, safety, and code compliance.

Question 5

Bid bond

Accepted Answer

A bid bond protects the owner if the selected bidder fails to enter the contract or provide required performance and payment bonds.

Question 6

Performance bond

Accepted Answer

A performance bond guarantees completion of the contract work if the contractor defaults.

Question 7

Payment bond

Accepted Answer

A payment bond protects subcontractors and suppliers by guaranteeing payment for labor and materials on the project.

Question 8

Addendum

Accepted Answer

An addendum modifies bidding documents before bids are submitted. Bidders must acknowledge addenda as required.

Question 9

Change order

Accepted Answer

A change order is a formal contract modification that can adjust scope, price, time, or other contract terms.

Question 10

Construction change directive

Accepted Answer

A directive can order changed work before final agreement on price or time, depending on contract terms.

Question 11

RFI

Accepted Answer

A Request for Information asks the design team or owner to clarify drawings, specifications, conflicts, or missing information.

Question 12

Submittal

Accepted Answer

A submittal provides shop drawings, product data, samples, or other information for review before procurement or installation.

Question 13

Shop drawing

Accepted Answer

A shop drawing shows how a contractor, supplier, or fabricator proposes to make or install part of the work.

Question 14

Punch list

Accepted Answer

A punch list identifies incomplete or deficient work that must be corrected near substantial completion.

Question 15

Substantial completion

Accepted Answer

Substantial completion means the owner can use the project for its intended purpose, even if minor corrective work remains.

Question 16

Final completion

Accepted Answer

Final completion occurs when all contract work, corrections, documents, and closeout obligations are satisfied.

Question 17

Critical path

Accepted Answer

The critical path is the longest sequence of dependent activities controlling the project finish date. Delay on it delays the project.

Question 18

Float

Accepted Answer

Float is time an activity can slip without delaying the project completion date or a controlling milestone.

Question 19

General conditions

Accepted Answer

General conditions are project overhead costs and requirements such as supervision, temporary facilities, insurance, and site administration.

Question 20

Quantity takeoff

Accepted Answer

Quantity takeoff measures materials, labor quantities, and work units from plans and specs to support estimating.

Question 21

Unit price

Accepted Answer

A unit price applies a price per measurable unit, such as cubic yard, square foot, linear foot, or each.

Question 22

Allowances

Accepted Answer

Allowances reserve money for items not fully defined at bid time. Final cost is adjusted when the actual item is selected.

Question 23

Contingency

Accepted Answer

Contingency is a budget reserve for known uncertainties or risks, not a substitute for estimating known scope.

Question 24

Lien waiver

Accepted Answer

A lien waiver documents that a party gives up lien rights for payment received or promised, depending on the waiver type.

Question 25

OSHA general duty concept

Accepted Answer

Employers must provide a workplace free from recognized hazards likely to cause death or serious harm.

Question 26

Competent person

Accepted Answer

A competent person can identify hazards and has authority to take corrective action.

Question 27

Excavation hazard priority

Accepted Answer

Cave-ins are a major excavation hazard. Protective systems, soil classification, access, and inspections are key safety concepts.

Question 28

Erosion control

Accepted Answer

Erosion and sediment controls keep soil on site and protect stormwater systems during construction.

Question 29

Compaction

Accepted Answer

Compaction increases soil density and support. Moisture content and lift thickness affect whether specified density is reached.

Question 30

Concrete slump

Accepted Answer

Slump measures fresh concrete consistency or workability, not final strength by itself.

Question 31

Concrete curing

Accepted Answer

Curing maintains moisture and temperature so concrete can hydrate and develop strength.

Question 32

Control joint

Accepted Answer

A control joint creates a planned weak line so shrinkage cracking occurs in a controlled location.

Question 33

Reinforcing steel purpose

Accepted Answer

Rebar helps concrete resist tensile forces because concrete is strong in compression but weak in tension.

Question 34

Mortar role

Accepted Answer

Mortar bonds masonry units, accommodates slight irregularities, and helps transfer loads through the wall.

Question 35

Weep holes

Accepted Answer

Weep holes allow water in a masonry cavity or veneer system to drain to the exterior.

Question 36

Flashing

Accepted Answer

Flashing directs water out of assemblies at vulnerable transitions such as walls, roofs, openings, and masonry cavities.

Question 37

Vapor retarder

Accepted Answer

A vapor retarder slows water vapor movement through an assembly. Placement depends on climate and wall design.

Question 38

Structural steel connection

Accepted Answer

Steel members transfer loads through bolted, welded, or otherwise engineered connections shown in the contract and shop documents.

Question 39

Light-gauge metal framing

Accepted Answer

Light-gauge framing is commonly used for noncombustible walls, partitions, and some structural applications depending on design.

Question 40

Engineered lumber

Accepted Answer

Engineered wood products such as LVL, I-joists, and glulam are manufactured for predictable structural performance.

Question 41

Load-bearing wall

Accepted Answer

A load-bearing wall supports structural loads from above; removing or altering it requires proper structural support.

Question 42

Rough opening

Accepted Answer

A rough opening is the framed opening prepared to receive a door or window unit with required clearances.

Question 43

Glazing coordination

Accepted Answer

Glazing work must coordinate glass type, frame, sealants, safety requirements, weather resistance, and installation tolerances.

Question 44

Drywall finish levels

Accepted Answer

Drywall finish level depends on final surface treatment and lighting; higher levels require more joint finishing.

Question 45

HVAC coordination

Accepted Answer

Mechanical work must coordinate equipment, duct routing, controls, clearances, penetrations, and access for maintenance.

Question 46

Plumbing rough-in

Accepted Answer

Rough-in places supply, waste, vent, and fixture connections before walls and finishes close the work.

Question 47

Electrical rough-in

Accepted Answer

Electrical rough-in installs boxes, conduit, cable, and pathways before insulation, drywall, or finish work covers them.

Question 48

Grounding vs bonding

Accepted Answer

Grounding connects to earth reference; bonding connects conductive parts together to reduce shock risk and help fault current clear.

Question 49

Coordination drawings

Accepted Answer

Coordination drawings help trades resolve conflicts among structural, mechanical, plumbing, electrical, and architectural systems before installation.

Question 50

NASCLA study priority

Accepted Answer

Master reference lookup, procurement and contracting, general requirements, safety, estimating, and the most common trade coordination concepts.
