Is the Red Seal welder exam a practical test?
The Red Seal exam itself is a written, multiple-choice exam. Your province may add practical requirements. Alberta's experienced-worker route, for example, works like this in trades that have a practical exam:
- Apply to AIT's Trades Qualifier - Work Experience program with proof of your work in the trade.
- Write the theory exam. AIT recommends scheduling the practical after you pass it.
- Pay the practical exam fee, then book it. It's run by AIT and must be done in Alberta.
- Finish every requirement within 18 months of approval.
