The NC One Water Plant Operations & Maintenance Committee holds two annual Maintenance Technologist certification schools, typically in the Spring and Summer of each year. Students can then register for one of three exam periods - one during the Spring, one during the Summer, or one in the Fall. Students must apply and be accepted to be able to take the exam.
Please note that these school schedules are subject to change based on instructor availability.

Renewals
Renewals of valid certificates are required every year, following the successful completion of the examination. In order to renew, technologists must submit six (6) hours of continuing education hours approved by NC DEQ for water OR wastewater operators. Certifications must be renewed every year by December 31, after which renewals are considered "late" and may result in an increased fee.
Renewal is accomplished either by (1) submitting continuing education hours and paying the renewal fee, or (2) by successful completion of the next certification level exam. Re‐examination at the level that is being maintained is not necessary for renewal.
When a technologist successfully completes their next MT certification level, they are automatically granted a renewal extension through December of the following calendar year. As an example, if an MT1 successfully passes their MT2 exam in June 2026, their renewal deadline will be automatically updated to December 2027, and no renewal fee is due until that deadline.
A notice will be sent as a reminder that renewal is required; however, timely renewal is the sole responsibility of the certificate holder. Click the following link for the current certification renewal form and follow instructions to complete renewal submission.

Exam Information
All MT Exams will be administered via computer-based testing (CBT). All eligible candidates will receive an email to schedule the exam. Exam costs are reflected in the registration price. No additional fees are required.
If you require any specific testing accommodations due to the Americans with Disabilities Act (ADA), please notify NC One Water at least six (6) weeks in advance to ensure arrangements are completed in a timely manner.
Exam Retakes
If a student fails their MT exam, they are eligible to retake the exam a maximum of three (3) times, as long as they pay the registration fee for each exam.
If a student fails the same MT certification level three times, they will be required to retake the MT school before they are able to sit for an exam again.
