Our Red Seal Carpenter bank has 40 questions on this topic. Here are 5 of them with answers; the full mock exam draws from every topic, like the real one.
Question 1
Studs in Canadian residential walls are most commonly spaced at:
- 400 mm or 600 mm on centre
- 200 mm on centre
- 1,200 mm on centre
- 800 mm on centre
Show the answer
A. 400 mm or 600 mm on centre — Standard spacings are 400 and 600 mm (16 and 24 in), matching panel sizes.
Question 2
Before raising a wall built flat on the deck, a carpenter should check it for square by:
- Sighting along the bottom plate
- Measuring the diagonals
- Measuring the top plate only
- Checking one stud for plumb
Show the answer
B. Measuring the diagonals — Equal diagonals mean the frame is square before sheathing.
Question 3
After a wall is raised, temporary diagonal braces are used to:
- Hold it plumb and secure until permanent framing is complete
- Level the floor
- Hold the insulation and vapour barrier in place until the drywall is installed
- Support the roof permanently
Show the answer
A. Hold it plumb and secure until permanent framing is complete — Bracing keeps walls plumb and safe against wind until the structure is tied together.
Question 4
When installing floor joists, the crown (natural bow) should face:
- It does not matter
- Up
- Toward the outside wall

Show the answer
B. Up — Load and drying tend to flatten an upward crown.
