Renewal Process

An applicator’s credential expires December 31 of every third year. Individuals receive a renewal application and information approximately three months prior to the expiration of their credential. Renewal may be obtained by accumulation of seminar credits or by taking renewal examination(s).

An applicator may not renew his or her credential before the renewal window opens the year the credential expires. The renewal window opens around the first week in October each year. (For example, if an applicators certification expires December 31, 2020, he cannot renew his certification before the first week of October in 2020.)


The renewal application fees are as follows:

  • Commercial application fee is $75
  • Registered application fee is $45
  • Private application fee is $50

Renewal by Examination

Once the renewal application is received, the applicator may take it and the appropriate fee with him or her to a paper-based exam site and take the tests that he or she needs. If the applicator chooses to attend a computer-based exam session, the applicator must mail the application with the appropriate fee (made payable to the “State of Michigan”) to: The Michigan Department of Agriculture and Rural Development, P.O. Box 30776, Lansing, Michigan  48909.

Exams are given by appointment only.  For computer-based exams, schedule online at Note: Computer-based exams have an additional service fee per test. Service fee(s) paid to Metro Institute have nothing to do with MDARD. Therefore, paper application and appropriate fee also need to be mailed to MDARD at the address above. 

Renewal by Seminar Credits

During the 3-year certification/registration period, pesticide applicators may obtain credits towards their renewal certification by attending eligible pre-approved seminars. See the list of seminars approved for recertification credits.

Seminar credits must be category specific. At the end of the 3-year certification/registration period, if the applicator has earned the proper number of credits, he or she can renew his or her credentials without taking an exam(s). It is the pesticide applicator's responsibility to keep track of the number of credits earned during the 3-year certification/registration period. The applicator may choose to keep track of the number of credits earned by utilizing the Seminar Attendance Record (also lists credit requirements).
