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. Premium opens every course to learn, with no timer and no credit. To earn credit and a certificate, take the course for credit: $20 a course, or the $150 Course Pass for every course for a year, with Premium included.

For You

Taking a course for credit costs $20, or $150 for the Course Pass.

The first part of every course is free, so you can try a course before you pay. Premium opens every course to learn with no timer, but that way gives no credit and no certificate.

Operator Master certificates count for renewal now in Alabama, Arizona, Idaho and South Carolina, with no course pre-approval. Other boards are reviewing the courses. Check with your board, and if it won't accept a certificate you paid for, we refund it (see below).

Course Pass + Premium

Already have Premium? The Course Pass is $100 for you; the price drops at checkout.
The pass does not renew on its own, so you are never charged again unless you buy it again.

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.
