If you farm in Illinois and use restricted use pesticides, you need your own license.

The private applicator license is built for exactly that. It is cheaper than a commercial license and has a shorter exam, and you can take it as a farmer without any company behind you.

This guide explains who needs it, which exam to choose, the fee and how renewal works. This site is an independent exam trainer. The license is issued by the Illinois Department of Agriculture (IDOA), and we are not affiliated with IDOA or the University of Illinois.

In short

  • The private applicator license is for applying restricted use pesticides to produce an agricultural commodity on property you own or control.1
  • It costs $90 for a 3-year license.1
  • Pass the 50-question Private Applicator exam (35 or more correct) or the 100-question General Standards exam (70 or more).1

Who needs it

PSEP describes the private applicator as a person applying restricted use pesticides to produce an agricultural commodity on property they own or control.1 A restricted use pesticide is one the EPA limits to certified applicators because of its potential to harm people or the environment.

If you spray general use products on your own farm, the private license is not what the rule asks for. Spraying for hire is a different matter. Individuals who use or supervise pesticides for hire need a commercial applicator or operator license.2

Which exam to take

You have two routes. Either pass the Private Applicator exam, which has 50 questions and needs 35 or more correct, or pass the 100-question General Standards or Aerial General Standards exam with 70 or more.1

ExamQuestionsTo pass
Private Applicator5035 correct
General Standards10070 correct
Aerial General Standards10070 correct

The Private Applicator exam is half as long as General Standards. Private applicators who apply by aircraft, including drones, can use the Aerial General Standards exam, and then submit the application and fee to IDOA.3

Cost and training

The license costs $90 for 3 years since the fee change on January 1, 2026.4 IDOA does not take credit or debit cards for licensing, so plan on a check or money order.5

Training is optional. PSEP lists $45 for the Private Applicator course, and online access lasts 30 calendar days.56 In-person workshops are offered for private applicators too, and testing at the workshop is free.6

Where to test

You can test in person at a clinic or an IDOA test-only session, which needs pre-registration and a photo ID, or online with ProctorU, which charges a fee for each attempt.65 The details are the same as for commercial exams, so see the General Standards guide for the comparison.

Renewal

Illinois licenses run on a 3-year cycle and expire on December 31.5 Exams taken on or after October 1, 2026 count through the end of 2029.7

A continuing education option is being written. It would let applicators use approved CEUs instead of retaking the General Standards and Private exams, targeted for the 2027/2028 licensing year. Until the rules are final, plan on retesting.45

Good stewardship on the farm

A few habits cover much of what the exam asks about:

  • Read the label before every application, including the pre-harvest interval. The interval is the minimum number of days between application and legal harvest and is listed on the label.8
  • Keep records of every application. Illinois sets a retention period for restricted use records, so confirm the current rule with IDOA.
  • Watch drift and weather before spraying, and talk to neighbors with sensitive crops.

Common questions

Is your practice test the actual exam?

No. The questions are our own. The exam is written and given by IDOA.
