How it works

This unofficial Colorado commercial pesticide applicator practice test asks 87 questions of our own on the Pesticide Applicators' Act and the state's exam guide. It is not affiliated with the Colorado Department of Agriculture or Metro Institute.

Read the full guide

The general exam

Qualified supervisors and certified operators take the general exam, then a category exam for each kind of work. The department's Licensing and Examination Guide, read October 8, 2026, lists seven subject areas for it. This Colorado pesticide applicator practice test is the state half of the first, laws and regulations.

What is left out

Labels, formulations, pest biology, safety, the environment and calibration are not here, nor are the federal acts the guide names. Federal label and worker protection rules are on the pesticide applicator practice test.

Exam mode

Exam mode draws 40 questions, our number, at the state's 70% pass mark. The guide allows two hours for the real general exam and gives no question count.

  • A technician may mix a restricted-use pesticide with the supervisor away, but may apply it only with the supervisor on site.
  • Records are kept three years by commercial applicators and two by private applicators.

Questions and answers

What is on the commercial pesticide applicator test in Colorado?

A general exam and at least one category exam, both closed book, true-false and multiple choice. The general exam runs two hours, each category exam one hour, and 70% passes, by the department's guide.

Is this a general Colorado commercial pesticide applicator practice test?

It practices one part of the general exam: Colorado's own law. The guide lists seven subject areas, and the other six, from labels to application, are not covered here.

Does it cover the private pesticide applicator test in Colorado?

Partly. The private applicator exam is separate and open book, with the study guide on screen. Some questions here, such as the two-year record rule, are about private applicators.

Where is the Colorado pesticide applicator study guide?

Study guides for the general exam and each category are sold through Colorado State University, and the department says not all exam material is in them. The private applicator guide is also a free download.

How much does the Colorado pesticide applicator test cost?

$41.50 per exam, paid online when you schedule through Metro Institute at least two days ahead. A qualified supervisor or certified operator license is a separate $100.
