What are my options if I fail one or more exams?

Testers are given 2 attempts total per category (ie. core, 901a, 901b, etc.). If the tester does not pass their required categories in the allotted attempts, the tester is required to submit an affidavit of training, signed by their supervisor (or provide a certificate of completion with the affidavit of training) prior to being reset by PSEP or WDA.
If the tester does not pass on the third (3^rd) attempt, the tester will be required to wait 45 days to retest or must attend a training approved by WDA and submit a certificate to WDA prior to retesting. A list of approved trainings is located at http://agriculture.wy.gov/online-training/pesticide-applicator
Wyoming does have a “direct supervision” regulation that allows a non-certified applicator to work under the direct supervision of a certified applicator. The supervised employee must be within 50 miles or 1 hour of Supervisor, direct phone or radio contact, AND all instructions for the employee must be in a written document.
