This question comes up every fall from people choosing a school, and it usually gets answered with whatever the person asking happened to do. Both routes work. The right one depends on where you are starting from and where you want to be in five years.
The credits below are from Alberta's Power Engineers Regulation. Other provinces handle school credit differently, so check yours.
The Two Routes
A 4th Class certificate program is typically about a year. NAIT's, for example, is a one-year program that prepares you to write the 4th Class exams. Some schools also offer the 4th Class theory as part-time or distance courses (Part A and Part B) with a separate power lab, which suits people who are already working.
A power engineering technology diploma is typically two years full time. SAIT describes its diploma as giving you the knowledge and skills to obtain your 3rd Class certification. It goes further and deeper than a 4th Class program.
When You Can Write Your 4th Class
A certificate program makes you eligible for the 4th Class exams when you finish the course (or, in Alberta, each part as you finish it: Part A for 4A, Part B for 4B).
The diploma does not make you wait two years. In Alberta, finishing the first full term of a two-year power engineering technology program makes you eligible to write the 4th Class exams.
Experience Credit Toward Your 3rd Class
This is where the routes genuinely differ. In Alberta, the 3rd Class certificate normally needs twelve months of qualifying experience. ABSA may credit part of that from school:
| What you completed | Credit toward the 12 months for 3rd Class |
|---|---|
| A power engineering course leading toward the 3rd Class exam | 6 months |
| A 2-year power engineering technology program | 9 months |
Further up, a 3rd Class holder who has completed a two-year power engineering technology program may be credited half of the experience required for a 2nd Class.
So the diploma buys real time back on the ladder. Whether that is worth a second year of school is the actual decision.
Steam Time for Your 4th Class Certificate
Whichever program you choose, the 4th Class certificate needs operating time on top of the exams. In Alberta that is six months assisting in a power plant over 250 kW, and some school labs count toward it: SAIT's 200 hour Fourth Class lab is accepted by ABSA as meeting the six month requirement. BC accepts 200 hours of approved power lab training.
When you compare schools, ask exactly how each program handles this. Does it include a lab that your regulator accepts? Is the lab a separate course with its own intake? A program that leaves you to find six months of plant time on your own is a very different proposition. Our guide to getting steam time for your 4th Class covers the other routes.
Who the Certificate Suits
- You need to be earning soon. One year of school instead of two, and you can be working in a plant while you build toward your 3rd.
- You are already working, or changing careers. Part-time and distance 4th Class courses let you keep your income. If you are coming from engineering or a trade, our guide to switching into power engineering covers credit you may already have.
- You are not sure the trade is for you. A year is a smaller bet than two.
Who the Diploma Suits
- You are young, with no plant experience, and can afford two years. You come out with the 3rd Class material covered and nine months of credit toward the 3rd Class experience.
- You know you want to climb. If 2nd Class is the goal, the diploma's credit carries all the way up.
- You want the broader technical background. A diploma goes deeper than a 4th Class program, which some people find makes the later papers easier.
What Neither One Does
Neither route excuses you from the exams. Every paper is 100 multiple-choice questions and you need 65 percent, whether you studied in a classroom or at a kitchen table. School teaches you the material, but it does not always give you enough repetitions under real exam conditions, and that is where a lot of people come unstuck. Plan on timed practice before you write, whichever program you choose.
Questions to ask any school before you enroll: Which exams does this make me eligible for, and when? Does it include a power lab my regulator accepts toward steam time? What experience credit does my regulator give for it?
Summary
A one-year 4th Class certificate program gets you writing exams and earning sooner. A two-year power engineering technology diploma covers the 3rd Class material and, in Alberta, earns nine months of credit toward the twelve months of experience for a 3rd Class, against six months for a course leading to the 3rd Class exam. Diploma students in Alberta can write the 4th Class exams after their first full term. Both routes still need operating time for the 4th Class certificate, so ask any school how it handles steam time before you sign up.
