Pesticide Applicator Training
Getting a pesticide license in Oregon takes five steps.
Confirm you need one. Choose your license type. Study. Pass your exams. Then apply with the Oregon Department of Agriculture (ODA).
The first exam most people take is called Laws & Safety. Oregon State University offers a free online course to help you prepare for it.
ODA publishes every rule you need. The catch is that the details are spread across several pages.
This guide brings the whole path together in plain language, so you know what to do first and what comes next.
The five steps at a glance
Oregon requires a license for specific kinds of pesticide work. You need one if you do any of the following (ODA):
What's a restricted use pesticide? It's a product the U.S. Environmental Protection Agency limits to certified applicators. The label says "Restricted Use Pesticide" at the top.
Most products sold in garden stores are general use, not restricted use.
Good to know
Most homeowners don't need a license. If you use general use products on property you own or lease, no license is required. School campuses are the one exception.
You must be at least 18 to apply for an applicator or trainee license (ODA).
Think of this as two choices.
Your license type depends on who you are. Your categories depend on what and where you treat.
Oregon has 10 license types. These are the most common (ODA):
| If you are... | License type | Exams you take |
|---|---|---|
| Applying pesticides for hire (you must work for a licensed Operator) | Commercial Applicator | Laws & Safety + at least one category |
| A business that sells pesticide application services | Commercial Operator | None (needs insurance and a licensed applicator) |
| Using restricted use pesticides on your own or your employer's non-farm property, such as a golf course | Noncommercial Applicator | Laws & Safety + at least one category |
| A government or tribal employee | Public Applicator | Laws & Safety + at least one category |
| A farmer or forester using restricted use pesticides on land you own or lease | Private Applicator | Private Applicator exam |
| A trainee working under a licensed supervisor | Pesticide Apprentice or Immediately Supervised Trainee | Laws & Safety (Apprentice) or none (Trainee) |
Aerial applicators, consultants and dealers have their own licenses. See ODA's license requirements for the full list.
Categories describe the kind of work you do. Examples include Agriculture, Ornamental and Turf, Right-of-Way, Aquatic, Forest, and Industrial, Institutional, Structural and Health.
Several have subcategories. Each category has its own exam, so choose the ones that match your daily work.
A common mix-up
There's no standalone "herbicide license" in Oregon. Herbicide work is a subcategory, such as Ornamental and Turf: Herbicide.
Structural pest control works the same way. It falls under the Industrial, Institutional, Structural and Health category.
Not sure which fits? Ask your employer, or contact ODA's pesticide licensing staff before you book exams.
Most license types start with the Laws & Safety exam. That makes it the best place to begin.
The exam covers the core knowledge every applicator needs:
Oregon State's Pesticide Applicator Pre-Certification Training: Laws & Safety is free, online and self-paced.
It includes 11 modules and takes about 16 hours. Each module has built-in assessments.
You can work through it over several sittings and review modules once you finish them.
The course comes from OSU's Pesticide Safety Education Program (PSEP). PSEP built it from training materials developed with ODA.
PSEP's lead, Kaci Buhl, also helps develop national pesticide manuals and exams.
What the course does and doesn't do
ODA's official study materials are the National Pesticide Applicator Certification Core Manual plus the Oregon Core Manual Addendum.
Both are free as PDFs from ODA. Print copies are sold through the Chemeketa Community College Bookstore (ODA study materials).
Each category exam has its own manual or exam outline. You'll find those on the same ODA page.
ODA doesn't publish official practice exams. PSEP's resources page gathers study materials in one place, including Spanish-language manuals and outlines.
You don't schedule exams through ODA. You book them through Metro Institute, the state's testing vendor (ODA exams).
Book early. Seats fill quickly. ODA suggests booking up to several months ahead.
To register, you'll need your full legal name, date of birth, email address, and a Social Security number or ITIN.
Testing center locations change from time to time. Confirm yours before exam day.
Didn't pass? Oregon's rules set no waiting period before a retake. You pay again for each attempt (OAR 603-057-0120).
This is the step people most often miss.
Certified is not licensed
Passing your exams makes you certified. It doesn't make you licensed. You can't legally apply pesticides until ODA issues your license (PSEP).
Here's how the last step works (ODA):
Incomplete applications close after 60 days. Double-check yours before you send it.
Applying late in the year? Applications received on or after November 17 are issued for the following year. They usually start in early January.
If you need your license sooner, say so when you apply.
Getting licensed is the first milestone. Staying licensed runs on two clocks.
To keep your certification without retesting, you earn recertification credits during that five-year cycle (ODA renewal):
| License type | Credits needed | Limits |
|---|---|---|
| Commercial, Public, Consultant | 40 per five years | No more than 15 a year |
| Private Applicator | 16 per five years | At least 4 core, no more than 8 a year |
| Pesticide Apprentice | 8 per year | At least 4 core |
If you come up short, you retake the exams.
PSEP's Pesticide Applicator Series offers on-demand online courses. Most are worth 1 ODA core credit each. You can take them any time of year.
PSEP also runs live webinars and in-person short courses each season. These include a recertification webinar in Spanish.
Don't wait until December. Credits can take up to two months to appear in ODA's records (PSEP FAQ).
A good place to start: ODA and You: Pesticide Licensing, Recordkeeping and Compliance. It's a one-hour course on license types and staying compliant.
Oregon is updating its licensing rules to match federal standards. New manuals and exams are expected before 2030.
Check with ODA before you book your exams.
Fees are set by ODA and its testing vendor. They can change, so check the linked pages for current amounts.
| Item | Cost | Source |
|---|---|---|
| Laws & Safety prep course from Oregon State | Free | OSU PACE |
| Each exam, each attempt | $58 | ODA exams |
| Applicator license, one category | $50, plus $7.50 per added category | ODA fees |
| Recertification courses from Oregon State | $35 per on-demand course | PSEP |
An example. A commercial applicator passes Laws & Safety and one category exam on the first try. That's $116 in exam fees, plus the license fee.
It depends on your schedule. The free Laws & Safety course takes about 16 hours. Exam seats can book up weeks or months ahead. After you pass, ODA takes about 2 to 4 weeks to process your application.
No. You can prepare online, but Oregon's exams are taken in person at a testing center booked through Metro Institute.
ODA doesn't publish an official practice exam. Oregon State's free course includes built-in assessments, and ODA's exam outlines show what the exam covers.
National prep sites often call it the core exam. In Oregon, it's called the Laws & Safety exam. "Core" usually refers to a type of recertification credit.
No. It prepares you for the Laws & Safety exam only. Use ODA's category manuals and exam outlines for category exams.
Usually not. Homeowners using general use products on property they own or lease don't need a license. School campuses are the exception.
No. Herbicide work is a subcategory within a license category, such as Ornamental and Turf.
Passing your exams makes you certified. You're licensed only after ODA processes your application and fee. You can't legally apply pesticides until then.
Use ODA's online license database.
Yes. The Laws & Safety and Private Applicator exams are offered in Spanish. PSEP's resources page links Spanish study manuals and outlines.
Oregon's licensing path is clear once you see it in one place.
Know your license type. Pass your exams. Send in your application. Then keep your credits current.
For most people, it all starts with one exam: Laws & Safety.
