Technical Certification

Technical certification cards are an individual's responsibility.

Certification cards


A personal certification card is made available to each Technician with a certification number.

An up to date printed or electronic certification card is required each and every year.

This card shows which discipline(s) a Technician is currently certified and its respectable expiration date.

Certifications will remain valid for five years; as long as, a technician attends a one-day recertification class in the season that their certification expires!

A limited amount of Online Recertification classes are available to be taken over the training season. The online exam must be taken by April 30 to qualify. After April 30, students will be required to register, pay and attend the full classroom training the following season.

  • Have you completed full Payment for your classes?

Aggregate Production Tester Certification currently does not expire!

Those with Aggregate Production Tester certification will have "YES" after the words "Aggregate Production" on their card. Some cards will show "Credit" after Aggregate Production. This means you have satisfied the Aggregate Production Tester prerequisite, but do not have Aggregate Production Tester certification.
