Which Path Are You On?
Apprentice writing the IP exam
You have finished your technical training and are booked to write the Interprovincial (IP) exam. Use our 8 full-length tests to pace yourself, find weak areas, and walk in ready.
Trade Qualifier / Challenger
You have around 7,200 hours of documented work experience but did not go through the apprenticeship schooling. You plan to challenge the Red Seal exam through your provincial Trade Equivalency Assessment. Our book covers the full NOA so you can close the gaps before exam day.
Rewriting after a previous attempt
If your last attempt did not go the way you wanted, use our detailed answer explanations to fix the knowledge gaps, not just memorize answers. Every question in the book has a written explanation.

What is the maximum on-centre spacing for 2×6 floor joists spanning 3.5 metres in a residential application, per the National Building Code of Canada span tables?
A. 300 mm (12 inches)
B. 400 mm (16 inches)
C. 500 mm (20 inches)
D. 600 mm (24 inches)
Answer: B
Explanation:
Standard residential framing uses 2×6 floor joists at 400 mm (16 inches) on centre for spans up to about 3.5 metres in No. 1 / No. 2 SPF lumber. Wider spacing (600 mm) is used for engineered lumber or when joists are deeper. Always confirm the exact span using NBCC 2020 Table 9.23.4.2 or the manufacturer span tables for the lumber grade and species being used.
What is the correct procedure for laying out a stair stringer with 8 risers and 7 treads?
A. Mark all 8 risers and 7 treads, then drop the bottom riser by the thickness of one tread
B. Mark all 7 risers and 8 treads, then drop the bottom riser by the thickness of one tread
C. Mark equal numbers of risers and treads
D. Drop the top tread by the thickness of one tread
Answer: A
Explanation:
A stringer always has one more riser than tread because the top tread is the floor above and the bottom riser sits on the floor below. After laying out 8 risers and 7 treads, the bottom riser is shortened (‘dropped’) by the thickness of the tread material so that, once the treads are installed, all riser heights are equal. This drop is essential — without it, the bottom riser ends up the thickness of one tread taller than the others.
A floor system uses I-joists at 600 mm on centre. After installation, the homeowner reports that the floor feels bouncy and dishes plates rattle in the cabinet when someone walks across the room. The joists meet code span. What is the most likely solution?
A. Replace all the joists with deeper joists
B. Install bridging or strongback at mid-span to stiffen the system
C. Add subfloor adhesive between joists and sheathing
D. Reduce the on-centre spacing to 400 mm
Answer: B
Explanation:
Floors that pass code span calculations can still feel bouncy because code addresses safety, not stiffness or vibration. The most efficient retrofit is to install bridging or a strongback (a 2×4 or 2×6 attached perpendicular to the joists at mid-span) which ties the joists together and dramatically reduces vibration. This is much cheaper than replacing joists. Subfloor adhesive helps prevent squeaks but does not significantly reduce bounce.

Carpenter Red Seal Exam — Frequently Asked Questions
What is the Red Seal Carpenter exam?
The Red Seal Carpenter exam is the national trade certification exam for carpenters in Canada. It tests the knowledge listed in the Carpenter Red Seal Occupational Standard. When you pass, you receive the Red Seal endorsement on your provincial Certificate of Qualification. This lets you work as a journeyperson carpenter in any province or territory in Canada without re-certifying.
How many questions are on the Carpenter 403A exam?
The exam has 125 multiple-choice questions. Each question has one correct answer out of four options. The questions are split across the six Major Work Activities in the National Occupational Analysis.
What is the pass mark?
The pass mark is 70%. You need to answer at least 88 out of 125 questions correctly to pass.
How long do I get to write the exam?
You are given 4 hours to write the exam. Most candidates finish before the time is up.
Can I challenge the exam without an apprenticeship?
Yes, in most provinces. You need to show around 6,000 hours of documented work experience in the trade through your provincial apprenticeship body. This route is called Trade Qualifier (TQ) or Trade Equivalency Assessment. Check the rules in your province before you apply.
Is the Carpenter Red Seal the same as the General Carpenter ticket in Ontario?
Yes. In Ontario the trade is registered as General Carpenter (Ontario code 403A) and the Ontario exam is the Red Seal exam. Passing in Ontario earns you both your Ontario Certificate of Qualification and the Red Seal endorsement in one sitting.
