In order to buy or use the riskiest pesticides, some applicators must become certified and licensed. Usually, they study for one or more exams, pay a fee, and maintain competency by taking classes over time. With their level of education about pesticide laws and safety practices, some states/tribes/territories allow them to 1) supervise unlicensed applicators, and 2) train unlicensed pesticide handlers in agriculture.

In keeping with our policies, PERC will not share manuals online in their entirety when they are associated with certification exams. For example, if a manual was used as the basis for an exam, that manual will not be available online. This is because many states rely on publication-related income to support other educational offerings for applicator communities.

States and tribes are welcome to use or modify the manuals and exams we create. Reach out to us at
