Continuing Education
Frequently Asked Questions:
- If you have 24 CEUs and your license does not expire in the coming year, DO NOT submit for a license renewal. You will lose the time between submitting the license renewal and your current expiration date. The Wyoming Department of Agriculture will not add an additional three years to your current expiration date. Regardless of the situation, a Wyoming Pesticide Applicators license will only be good for three years.
- The Department of Agriculture keeps track of CEU's submitted to the department but our system is not perfect. Sometimes sign in sheets get misplaced or not submitted. Sometimes license numbers or names are not legible. Sometimes e-mails get lost. The point is, in the end, it is your responsibility to prove to the department that you received CEU's come time to renew your license. It is advisable to keep a record of your CEU attendance in case you need to prove you attended a conference/event.
- If you do not agree with the amount of CEUs that have been awarded to you, we encourage you to dispute it. This can be accomplished by sending proof of attendance (agenda is essential) to the Wyoming Department of Agriculture, Attn: Technical Services Division.
