How our classes work
Enviro-Clear classes are held virtually, with in-person sessions offered as possible. Class dates are confirmed when you register — pick a course below and reserve your seat.
Virtual on Microsoft Teams
Live, instructor-led sessions held on the Microsoft Teams platform — join from anywhere, no travel required.
Payment options
Blue or green MDNR vouchers accepted. Check and card payments (card processed through Square for a small processing fee) are also accepted.
Real-world video clips
Classes are virtual, so hands-on instruction isn't possible — relevant video clips are shared instead to demonstrate real-world plant and lab work.
Continuing education credit
Courses align with WPI ( formerly ABC) Need-To-Know Criteria and count toward CEU requirements.

Enviro-Clear Inc. is not responsible if a student does not pass their certification exam. Certification exams draw from thousands of potential questions based on the sources published in the WPI criteria — the same sources we use in our training — and significant individual effort is required by students to be successful.
We do not publish pass rates because the state has not tracked them. What we can tell you: Mary Alice works closely with operator certification in Missouri and has with Hawaii — the two main states our certification students come from — and she will do all she can to help every student be successful.
If a student does not pass, they may reapply immediately; however, PSI (the exam company working with WPI) requires a 60-day waiting period between attempts. Private tutoring is available for students who want extra help before a retake.
