Technical Certification


Certification cards


Every June, we send out laminated certification cards to every individual who has at least one certification in our program database. This card shows what discipline(s) they are certified in and when the expiration date is. Certifications are good for five years and technicians must attend a one-day recertification class in the season that their certification expires to renew their certification. There are four online recertification classes that can be taken over the course of the training season, but the exam must be taken by April 30 or students will have to register and pay for the class again next season.

Report changes

To report an address or employer change, contact John Micheau. Please provide:

  • Your name
  • MnDOT Tech ID number (5 digits beginning with a 0 or 1)
  • Daytime phone number
  • Brief description of the problem (e.g. "Missing Level 2 Bituminous Plant")

Corrected cards will be mailed in approximately two weeks from the time we receive your request.

I never received my card

Please contact John Micheau if you did not receive a certification card. Note that you may not have received a card this year because:

  • We do not have a valid address for you
  • You completed a certification class, but have not yet fulfilled all the requirements for at least one certification
  • All your certifications have expired (you did not complete a recertification class)
  • Payment is due for a class

Aggregate Production certification

Aggregate Production certification does not expire. Those with Aggregate Production 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 prerequisite, but do not have Aggregate Production certification.
