Sample NV C-3B Finish Carpentry Practice Questions

Try these sample questions to test your NV C-3B Finish Carpentry exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Under NAC 624.210(b), what work does a Nevada C-3B Finish Carpentry license authorize?
A.Framing, roof sheathing, and structural stair stringers for new buildings
B.The installation, repair and finishing of cabinets, sash casing, door casing, wooden flooring, baseboards, countertops and other millwork
C.The installation of ceramic tile, marble, and cultured-stone countertops
D.The hanging of overhead garage doors and their tracks
Explanation: NAC 624.210(b) defines subclassification C-3b as the installation, repair and finishing of cabinets, sash casing, door casing, wooden flooring, baseboards, countertops and other millwork. Structural framing is C-3a, overhead doors are C-3d, and tile or stone is outside C-3B. The closed-book PSI C-3B exam tests that millwork scope.
2Which of the following is expressly outside the Nevada C-3B Finish Carpentry scope?
A.Installing a plastic-laminate kitchen countertop
B.Hanging factory-made wall cabinets
C.Setting a cultured-marble vanity top
D.Fitting oak baseboard and shoe moulding
Explanation: NAC 624.210(b) states that finish carpentry does not include ceramic tile, marble, and artificial or cultured stone. A cultured-marble vanity is therefore outside C-3B. Laminate and wood countertops, cabinets, and millwork trim remain inside the classification.
3How should a finish carpenter join profiled baseboard at a typical inside corner?
A.Butt both pieces square and fill the gap with caulk only
B.Cut a full-blind dovetail in the base
C.Leave a 1/4-inch expansion gap at the corner
D.Cope the profile of one piece to the face of the other
Explanation: Coping cuts one moulding to the negative of the adjoining profile so the joint stays tight when walls are out of square or the wood moves. It is the standard inside-corner method in the Finish Carpenter's Manual for base, chair rail, and many casings. Outside corners are mitred.
4On a long straight run of baseboard, what joint is preferred where two pieces meet in the middle of the wall?
A.A scarf (long bevel) joint sloped so the face hides the seam
B.A square butt left unglued
C.A 90-degree miter with the short point against the wall
D.A half-lap cut only with a circular saw
Explanation: A scarf joint — typically a long 30- to 45-degree bevel — lets two pieces meet along a run with a less conspicuous, more glueable seam than a square butt. Face the long point toward the main viewing direction so the joint is harder to see. Locate the scarf over a stud when possible.
5What is the main structural difference between face-frame and frameless (European) cabinet boxes?
A.Frameless cabinets cannot accept adjustable shelves
B.Face-frame cabinets have a hardwood frame applied to the front edges of the box; frameless cabinets use the box edges themselves as the door landing
C.Face-frame cabinets are always made of solid lumber with no sheet goods
D.Frameless cabinets cannot be used in kitchens
Explanation: A face-frame cabinet has rails and stiles glued and fastened to the front of the carcass; doors land on that frame. A frameless (32 mm) cabinet has no front frame — the 3/4-inch box edges are edged and the doors overlay those edges. Both systems are standard millwork and both are inside C-3B.
6In a cope-and-stick cabinet door, what does the cope cut do?
A.It rabbets the door for a glass pane only
B.It is the groove that holds the panel and nothing else
C.It cuts the negative of the stick profile on the rail ends so the rail-to-stile joint closes on the moulded profile
D.It is a decorative groove cut after the door is assembled
Explanation: Stick cutters mould the inside edge of stiles and rails and usually cut the panel groove. Cope cutters cut the matching negative profile on the rail ends so the joint meets on the moulded faces rather than on a square shoulder. The panel then floats in the groove.
7Which joint is the usual shop method for housing a fixed shelf in a plywood cabinet side?
A.A half-blind dovetail cut only with a handsaw
B.A biscuit joint with no supporting shoulder
C.A nailed butt with no glue
D.A stopped or through dado sized to the shelf thickness
Explanation: A dado — a groove across the grain, or across a plywood panel — gives the shelf a full-width shoulder to sit on and is the standard casework joint for fixed shelves, cabinet bottoms, and stretchers. Stop the dado if the shelf must not show on a finished front edge. Glue plus mechanical fasteners complete the joint.
8Why must a solid-wood raised panel float in the frame rather than be glued all around?
A.Seasonal width change would split the panel or blow the frame joints if the panel were locked in
B.Glue would stain through any finish
C.Building code forbids glue in interior doors
D.Floating the panel reduces the door's fire rating
Explanation: A solid panel shrinks and swells across the grain. The grooves are cut deep enough (typically about 1/16 to 1/8 inch extra on each side) so the panel can move. A spot of glue at the top center, or space balls, can rattle-proof the panel without locking the sides. Frame-and-panel is the classic millwork answer to wood movement.
9For a hardwood face frame that will be stained, which joint is the traditional shop standard at rail-to-stile intersections?
A.A nailed butt with no glue
B.Mortise-and-tenon or a well-fitted dowel or pocket-screw joint with the pockets on the hidden face
C.Hot-melt only, so the frame can be disassembled
D.Construction adhesive with no mechanical joint
Explanation: Mortise-and-tenon is the traditional stained face-frame joint. Modern shops also use dowels, dominos, or pocket screws driven from the back so the show face stays clean. Glue area and mechanical lock matter more than the brand of fastener. Nailed butts creep and telegraph under stain.
10Which drawer-box corner joint is the traditional high-quality millwork choice for a hardwood drawer that will be heavily used?
A.A single finish nail at each corner
B.Masking tape until the glue skins
C.Half-blind or through dovetails
D.A butt joint with hot-melt only
Explanation: Dovetails lock the sides to the front against the pull-out load and are the traditional drawer joint in the Finish Carpenter's Manual and AWI casework practice. Half-blind dovetails hide on a solid drawer front; through dovetails show. Dadoed backs and glued bottoms complete a standard box.
