Exam & certification information
About the Heavy Duty Equipment Red Seal exam.
The published examination has 135 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.
Local trade titles may differ. Prepare for the national scope, including equipment and systems that are less common in your own workplace.
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.
