Pesticide License Testing 2022

OSU Extension Wayne County has set up testing dates with the Ohio Department of Agriculture (ODA) for the 2021 year to allow private and commercial applicators to obtain a pesticide applicators license. To obtain a license, applicators must take and pass a core exam plus one or more specific category exam(s). The cost of a private applicator license is $30 and a commercial applicator license is $35.  ODA personnel administer the tests. All testing will take place in the commissioners meeting room located on the top floor of the Wayne County Administration Building at 428 West Liberty Street in Wooster.  Exams are administered from 9:00 am until noon and 1:00 pm until 4:00 pm on the following dates:

There are a limited amount of spaces available for each testing session.  Once the spaces are filled, the testing session is closed.  Register to reserve a spot online at, or by phone to the ODA Pesticide Division at 614-728-6987, then press 1 for pesticide licensing.

Anyone taking an exam will be required to show photo identification or some form of identification.

Private applicators are encouraged to obtain study materials from the Wayne County Extension office before taking the exam.  In addition, some study materials are available on-line.  More information about study materials for private pesticide applicators is available on-line at .
