Exam & certification information
About the Sheet Metal Worker Red Seal exam.
The published examination has 120 four-option multiple-choice questions, a four-hour writing time and a 70% passing mark. Our two full forms match that length, time and published task distribution. The questions are independently developed.
The trade includes more than duct installation. Review fabrication, architectural products, commissioning and repair against the national scope.
Your provincial or territorial authority determines eligibility, fees, booking and permitted references. This study package does not register you for the official exam or confer certification.
