Renewal Process

An applicator’s credential expires December 31 of every third year. Individuals will 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 in year that the credential expires. The renewal window opens approximately the first week in October each year. (For example, John Doe’s certification expires 12/31/2019. He will not be able to renew his certification before the first week of October in 2019.)


The renewal application fees are as follows:

  • Commercial application fee is $75.00
  • Registered application fee is $45.00
  • Private application fee is $50.00

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 will need to 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.  Schedule online at for paper-based exams or call 1-800-292-3939. Schedule online at for computer-based exams. (Note, computer-based exams have an additional $55 fee per test). For more detailed information about our exam options, check out the Examination Process.

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. Our website has a list of seminars approved for recertification credits that is arranged by month.

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).
