Iowa Department of Agriculture and Land Stewardship Expands Online Pesticide Applicator Testing Options

Applicators are also encouraged to apply for certification using the online system

DES MOINES, Iowa (Jan. 10, 2022) – Iowa Secretary of Agriculture Mike Naig announced today that the Iowa Department of Agriculture and Land Stewardship’s Pesticide Bureau has expanded the option for online testing to all commercial and private pesticide applicator category exams. The Department also strongly encourages pesticide applicators to apply for certification using the online self-service portal to avoid delays in the spring.

“The online testing platform gives commercial and private pesticide applicators the flexibility to take the exam from their homes or offices at a time that works for them,” said Secretary Naig. “The expansion of online testing options, along with the Department’s new online pesticide self-service portal, are examples of our continued focus on customer service across the Department. We encourage applicators to take advantage of these online options as they work to get certified for the upcoming growing season.”

Online Commercial Pesticide Applicator Testing

All commercial pesticide category exams are now available online. Commercial pesticide applicators can create an account to take the online exam at The online exams are monitored, recorded and reviewed by a third-party proctoring service. A web camera, high-speed internet connection and government-issued photo ID card are required for online testing. There is a $25 fee for each commercial pesticide applicator test completed online, payable directly to the third-party online testing service.

Commercial pesticide applicators will receive a preliminary pass/fail test result as soon as they complete the online exam; these preliminary results cannot be used to apply for pesticide applicator certification. The third-party proctoring service will certify the test results and send the final scores to the email address used to register for the exam. Feedback on test results is only available at in-person testing sites and will not be provided for online exams.
