Passing the exam is not the end. An Ohio pesticide license has to be renewed, and every three years you also have to recertify.

Many applicators miss this because the annual renewal and the three-year recertification are two different things. One is a fee, the other is training time.

This guide covers both, for commercial and private licenses. The license is issued by the Ohio Department of Agriculture (ODA). This site is an independent practice test site and is not affiliated with ODA or OSU.

In short

  • Commercial: 5 hours of credit every 3 years, including 1 hour of Core and half an hour per category.12
  • Private: 3 hours of credit, including 1 hour of Core and half an hour per category.3
  • You can retest in Core and each category instead of attending training.23
  • Commercial licenses expire September 30 and cost $35 a year. Private licenses expire March 31 every three years and cost $30.23

Commercial recertification

A commercial applicator needs a minimum of five hours of recertification credit every three years. The credits must include 1 hour of Core and at least 30 minutes in each category on your license. The rest can be in any category.21

Example: with two categories, 1 hour of Core and 1 hour for the categories makes 2 hours. The other 3 hours can be added in any category.

You can collect the five hours in half-hour steps over the three years, and you must be done by the September 30 deadline.2 Wood-destroying insect inspectors also need 5 hours, with 1 hour of Core and 4 hours in any category.4

Private recertification

A private applicator needs three hours: 1 hour of Core, at least half an hour per license category, and the remainder in any private category.3

The private license expires every three years on March 31. ODA mails a renewal letter in December of the last year, with a statement of your recertification status. You can renew and pay online or by mail, at $30.3

Renewing late

The Ohio Revised Code says a renewal filed after the deadline gets a 50 percent penalty added to the fee. If a license is not renewed within 180 days after it expires, the person must take the exam again.5

The same section lets commercial and private holders renew within 180 days without re-examination unless the director decides a new exam is necessary.5

Finding a class

OSU lists commercial recertification meetings and webinars on its Commercial Recertification page, with in-person days in several Ohio cities and webinars by category for early 2027. There is also a self-paced course and a look-up tool for your status.1

For private applicators, OSU Extension county offices run programs in nearly every county, usually for a fee. ODA also has a private recertification class search.3

Common questions

How often do I recertify?

Every three years, for both commercial and private licenses.23

Do I pay a fee to renew each year?

Commercial applicators pay $35 each year. Private applicators pay $30 once per three-year license.23

Can I check my credits?

Yes, OSU offers a recertification status look-up.1

Do trained servicepersons recertify?

They hold no license. They need training before first exposure and the employer keeps the records for three years after they leave.4
