Pesticide Exams

To get a new pesticide license, or to add a category to an existing license, candidates will need to pass one or more exams.

  • For new licenses, the core exam and at least one category exam must be passed. In addition, the license application and fee must be submitted within one year of the exam date.
    • The exam proctor will provide you with an ID number when you arrive at the appointment. You will need this number to look-up your test results later and will later be used as your license ID.
  • For those with an existing license, once a new category exam is passed it will automatically be added to the license and re-issued.

Exam sessions are offered at no cost around the state throughout the year and are proctored by our inspectors. Seating is limited at these exam sessions, and it is strongly recommended that you register for an appointment to guarantee a seat.

Exams will be graded within 10 business days. Results will be available to check online at that time, and will also be mailed to the candidate. Due to security concerns, we do not provide exam scores over the phone.


After selecting an open exam session you will be asked to select the exams you want to take during that  session. Candidates can only be registered for a maximum of 2 exam sessions at a time, and must have at least 5 business days between sessions. Multiple exams may be taken during a session, if time allows.

You will receive an email confirmation once the appointment is scheduled.

  • Photo IDs will be required; pencils and calculators will be provided.
  • Candidates can only be registered for a maximum of 2 exam sessions at a time, and must have at least 5 business days between sessions.
    • Multiple exams may be taken during a session, if time allows.
  • If you have scheduled future exams but no longer need it, or cannot attend a scheduled session, please call us as soon as possible to cancel your appointment. This will free up the limited seating for others.
