Steps to Successfully Completing a Pesticide Certification Exam

The MDA is the authority regulating pesticide use in Minnesota. Persons applying pesticides in Minnesota may need to obtain a license from MDA to do so. By taking and passing a certification exam a person demonstrates they are qualified to hold a license.

The MDA issues different license types with specific categories depending on the intended application site. Persons must determine what type of license they need (Structural, Commercial, Noncommercial) and the categories in which they need to certify.

Private Applicators (typically farmers) apply and test through the University of Minnesota.

Preparing for the Exam

  1. Every person must pass the Core Exam (Category A) and at least one additional exam category. Aerial applicators must pass the Core Exam (Category A), Aerial (Category B) and at least one other category. Study Materials for the exams may be ordered from University of Minnesota Bookstores Extension Publications online or call 612-301-3989. 
  2. Pay application fees, these fees and surcharges are non-transferable and nonrefundable. MDA strongly encourages new applicators to apply online  prior to the testing appointment.  Otherwise complete the application form including the name, address (physical and mailing address, if different) and phone number of your employer. Provide your social security number. Certify that the financial requirements are met.  Bring the complete application and payment to the testing location.  If you were licensed in the previous calendar year and are required to retest, you will need to bring the renewal form with payment or payment receipt to your testing appointment.
  3. Select a testing location.  
  4. If you require accommodations under the Americans with Disabilities Act, you must document your request in writing and submit it to Pesticide.Testing@state.mn.us no later than seven days before the exam.
