Appearance

Operator Master is independent and is not affiliated with WPI, PSI, ABC, the Washington State Department of Ecology or any other state or provincial certification agency.

Prices

Pricing and Payment

Practice questions are free for everyone. Courses cost money only for operators whose certificate is from Alabama, Arizona, Idaho and South Carolina, where Operator Master certificates count for renewal now. Everywhere else, the whole course and its certificate are free until your board accepts the courses.

For You

Do you pay? It depends on your certificate state.

If your operator certificate is from Alabama, Arizona, Idaho and South Carolina, the prices below apply. If it is from anywhere else, courses are free for you.

One Course

$20 per course

One course, with its final, its certificate and any retakes. It has no end date.

Checking your account…

Yearly Pass

$150 for 365 days

Every course for 365 days from the day you buy. It does not renew on its own, so you are never charged again unless you buy it again.

Checking your account…

Prices are in US dollars. Sales tax is added at checkout where the law requires it. You pay on a secure Stripe checkout page, then come back here.

Utility and Team Plans

A utility can cover its whole crew with one yearly invoice, due in 30 days. Each operator gets every course for one year, and supervisors see their crew's courses, scores and certificates. $100 per operator per year for 1 to 9 operators; $80 per operator per year for 10 to 24 operators; $60 per operator per year for 25 or more operators.

To set one up, email support@operatormaster.com. Already on a plan? Ask your supervisor for an invite link, or open the Supervisor Dashboard.

Paid Courses and Refunds

If your state or provincial certification board will not accept an Operator Master certificate you paid for, email support@operatormaster.com within 90 days of purchase and we will refund it in full. A refund ends paid access to what was refunded. Certificates already issued stay on record. Read the terms.
