Official exam informationMillwright Red Seal exam: questions before you book
Ontario details come from Skilled Trades Ontario, checked . Other provinces and territories set their own rules, so confirm yours with your apprenticeship authority.
How many questions are on the Millwright Red Seal exam, and what is the pass mark?
135 multiple-choice questions in four hours, with a 70% pass mark. Each question has four choices and one correct answer, according to the Red Seal Program’s exam preparation guide. The exam guide on this site breaks the questions down by work area.
Can I write the exam in French?
Yes. The Red Seal exam preparation guide asks you to confirm your exam language (English or French) when you register. In Ontario, Skilled Trades Ontario says exams are available in English or French only. Every question in the app is available in both languages.
Is the Red Seal exam online?
In Ontario you write it in person at an exam centre. Skilled Trades Ontario delivers certifying exams itself, and Red Seal exams there may be written on a computer through the rsexam.ca system with an invigilator present. Your exam confirmation email says whether your location uses it. In other provinces, check with your apprenticeship authority.
How much does the exam cost in Ontario?
Skilled Trades Ontario lists an exam fee of $150 plus HST, paid through the STO Portal. Apprentices who completed an Ontario training agreement do not pay it for their first attempt. Experienced workers who apply to challenge the exam also pay $235 plus HST for the Trade Equivalency Assessment. Other provinces set their own fees.
How long do I wait to rewrite the exam in Ontario?
30 days. Skilled Trades Ontario says there is a mandatory 30-day waiting period before you can retake an exam you did not pass, and you pay the exam fee again before rebooking. Rewrite rules differ between provinces and territories, so confirm yours with your apprenticeship authority.
Can I challenge the 433A exam without an Ontario apprenticeship?
Yes, through Skilled Trades Ontario’s Trade Equivalency Assessment. You need verifiable proof of the trade’s skills and experience at least equal to the full apprenticeship, school hours included (8,000 hours for 433A). If you are approved, you can write the certifying exam, and after passing you pay a fee to receive the Certificate of Qualification.
