Grading System: Percentage

 

Passing Grade: 70%

 

Percentage of Individual Work: 100

 

Additional Comments:
Students are required to sign and adhere to the Trades and Apprenticeship Safety and Attendance Rules and Regulatory Practices for Students Policy.

If a student fails to obtain the pass mark on the final exam, the student will be allowed one supplementary exam. The successful completion of the supplementary exam would allow a student to pass with a grade no higher than 70%.

A minimum of 70% on the final exam is required to write Part B of the BC Safety Authority 4th Class Power Engineering Interprovincial Exam.
