    • Metropolis Resort and Conference Center, Eau Claire

  • Due to the expiration of the temporary certification (Oct. 31, 2020), registration for the online tests will stop on Oct 1, 2020.
  • If you have a temporary certification number (number-T) you will be able to use that number to take the in-person exam once DATCP is providing it.  There will be no additional charge.
  • The PAT program is not scheduling any live in-person training / review sessions in 2021.  We will host online training through Zoom, but unfortunately, the test will not be connected to the training at this time.  Registration is available through the PAT Store.  You must register to be accepted into the Zoom session.  [ How to Join a Zoom Meeting ]

For questions about certification, licensing, testing, regulations and pesticide laws please contact the Wisconsin Department of Agriculture, Trade and Consumer Protection at datcppesticideinfo@wi.gov.  If you have questions about training materials and test access please contact the UW PAT Program at patprogram@mailplus.wisc.edu.

Please be advised that pdf delivery is not automated.  Your order will be processed. We aim to process orders the same day they are received (if received before 4 p.m.).


What is the PAT Program?

The University of Wisconsin Pesticide Applicator Training (PAT) Program develops and provides educational material to help you become certified to apply pesticides in Wisconsin. In order to become certified, you must pay a certification fee to obtain some of these educational materials. You can learn more about the certification process on the “Certification” page.

Before ordering, you should determine whether you are a “commercial” or “private” applicator, because your options are different for each. You can find out the difference between commercial and private applicators by clicking on the “certification” or the “ordering materials” menu link above.

There are many different categories you can get certified in (list of categories here). With your certification fee, you can choose to get a printed manual, a PDF manual, or an online course (for some categories only). Don’t know which to choose? Check out this podcast for an introduction to these choices:  What Should I Order?

Having trouble navigating through our online ordering process? Here’s a podcast that explains how to do it.

After you have studied the training material, you will have to take and pass a certification exam to become certified. Note: The UW PAT program does NOT write or process the certification exam.  The UW PAT Program does not have access to your test score.  The following is a link to DATCP’s exam scheduling site (which also shows the testing centers around the state: Online Pesticide Exam Scheduling.

Commercial Applicators

Private Applicators



Training Registration Certificates for commercial applicators are folded and placed between the front cover and the first page of your manual. DO NOT lose this certificate. You must bring this page with you when you take your certification exam. The exam proctor from the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) will collect it. Your exam will not be processed without the certificate. Manuals will no longer have this certificate as a tear out page as it was in the past. If you lose this form there is a $10 fee to replace it.

The Wisconsin Department of Agriculture, Trade and Consumer Protection’s Role in Certification

DATCP enforces the pesticide laws in Wisconsin.  DATCP also writes and administers the certification exams and grants certification. DATCP also issues individual pesticide applicator and pesticide application business licenses in the state.   Note: The UW PAT program does NOT write or administer the certification exam. Also, the exam is NOT given at the UW-Madison campus. Exams are given ONLY at DATCP test-only facilities or at training/review sessions.  DATCP provides the test location on the receipt you get when you schedule an exam. You need to contact DATCP (see below) for any questions dealing with scheduling an exam, exam results or any other exam-related questions.
