What your students practice

The Red Seal Plumber exam is the interprovincial certification exam for plumbers in Canada (trade code 306A in Ontario). It has 125 four-option multiple-choice questions, you have up to 4 hours, and you need 70% to pass. Questions follow the 2023 Red Seal Occupational Standard's seven Major Work Activities, with sewers, sewage treatment and DWV systems (26%) and water service and distribution (19%) the largest, and code questions are based on the National Plumbing Code of Canada 2020.

Tigertest's practice follows the Red Seal Plumber exam information and weightings (2023 RSOS) and the Red Seal Exam Preparation Guide, checked October 2026. Students train in short sets where missed questions come back until they are mastered, then take full practice tests.

  • Common Occupational Skills
  • Pipe Preparation & Joining
  • Sewers, Sewage Treatment & DWV
  • Water Service & Distribution
  • Fixtures, Appliances & Water Treatment
  • Hydronic & Low-Pressure Steam
  • Specialized Systems

Questions teachers ask

Is the Red Seal Plumber class free?

Yes. Classes are free for teachers. A student in your class also gets that test's full stats and every step of it at no charge.

Do my students need accounts?

No. A student opens your class link, types the name you know them by and starts practicing. An account is optional and keeps their progress across devices.

What do I see as the teacher?

Who practiced and when, each student's practice test scores, the Red Seal Plumber topics the class is weakest on, and every question the class answered with how many missed it and which wrong answer they picked.

Can I use my own questions too?

Yes. Any account can turn its own material into a Tigertest quiz and limit it to one class, so only your students can play it.
