3.4 Recertification, CEUs, Reciprocity, and Enforcement

Key Takeaways

  • OAC 35:30-17-6: each certified applicator recertifies every five years; within 12 months of expiration, pass a Phase II exam or earn the specified CEUs.
  • If the applicator elects re-exam and does not pass Phase II within 12 months of expiration, the person must retake Phase I and Phase II and the practical when applicable.
  • ODAFF: categories share a five-year recertification calendar (not a personal anniversary); CEUs earned in the year of certification do not count; the recertification procedure fee is $50 by CEU or $95 by retest.
  • Verified OSU/OAC CEU examples: Category 1a Agricultural Plant 20 CEUs in five years (max 10 in any one year); 1b Agricultural Animal 5 (max 2); 3a Ornamental and Turf 20 (max 10); 7a/7b 20 (max 10); 7c Fumigation 10 (max 5).
  • Pesticide complaints go to Damardray Williams, ODAFF Pesticide Complaint Program Administrator, 405-522-5981, using a PESTICIDE COMPLAINT STATEMENT; the inspector does not estimate monetary losses.

Why Recertification Is Not Your Birthday

Passing Core in 2026 does not start a private five-year clock that nobody else shares. OAC 35:30-17-6(a) says each certified applicator shall seek recertification every five (5) years. ODAFF's public CEU Recertification Guide is more concrete: each category recertifies on a five-year schedule not based on the date the individual was certified. All certified applicators in a given category share the same window (ODAFF's examples are spans such as 2020–2024 or 2022–2026). ODAFF's own illustration: a person who initially certifies in Ag Plant in 2019 recertifies in 2023, because that is the year the category recertifies — not 2024 from a personal anniversary. Confirm the live "Recertify in" column on the OSU Pesticide Applicator Certification Categories table before you plan CEU travel; those year stamps move when a cycle rolls.

Two Lawful Paths: Phase II or CEUs

OAC 35:30-17-6(b): within twelve (12) months of expiration, a certified applicator shall either pass a Phase II examination or earn the specified number of Continuing Education Units approved by the Department. If the applicator elects to re-examine and does not pass Phase II within twelve months of expiration, the applicant shall retake the Phase I and Phase II examinations and a practical examination, when applicable. That is the expensive miss: skip the CEU path, miss the Phase II window, and you are back to Core (Phase I) plus category (Phase II) plus 7a/7b/7c practical at OSU Stillwater if the category requires it.

If the applicator elects CEUs, approximately one hour of education equals one CEU. ODAFF's published recertification procedure fee is $50 for the CEU path or $95 for retest. Those procedure fees are not the same as a business-license renewal.

CEUs accrued during the year of certification do not count toward recertification. ODAFF repeats that note on the pesticides page. A January 2026 initial 3a certificate does not get to bank the February 2026 turf seminar toward the 3a cycle that is already running for everyone else in 3a.

OAC 35:30-17-6(c) adds counting rules:

  • No more than one-half of the total credit units shall be accepted for any one calendar year (this matches the "max in any one year" column).
  • Credit units shall be obtained in at least three (3) of the five (5) years, in any combination, so the five-year total is met.
  • CEUs may be prorated if the applicator's recertification period is shorter than five years.
  • The Department may allow a CEU to be credited to more than one category.

CEU programs are reviewed by the Department and the OSU Pesticide Coordinator. Awarded CEUs are not valid for more than five years after approval; after that the course is resubmitted. Print your name, include your certified applicator number, and keep your own log of date, place, and CEUs — the sign-in sheet is how the credit exists.

Verified CEU Totals (Do Not Guess the Rest)

Cite only figures you can point to in OAC 35:30-17-6 and the OSU category table. Examples:

CategoryTotal CEUs in 5 yearsMax in any 1 year
1a Agricultural Plant2010
1b Agricultural Animal52
2 Forest105
3a Ornamental and Turf Outdoor2010
3b Interiorscape105
3c Nursery/Greenhouse157
6 Right-of-Way157
7a General Pest2010
7b Structural Pest2010
7c Fumigation105
8 Public Health157
10 Demonstration and Research2010
15 Aerial52
16 Private Applicator2010

A 1a applicator cannot dump all 20 into a single winter. The max is 10 in any one year, and credits must land in at least three of the five years. A 1b applicator needs only 5 total but only 2 in any one year — that is a different pacing problem. If another category's number is not in this table, look it up on the live OSU chart or in 35:30-17-6; do not invent it in the testing center.

CEU content over the five years is supposed to cover laws and rules; pesticides (formulations, registration, labels, handling, toxicity); equipment and calibration; pests and IPM; hazardous areas; drift prevention; endangered species; groundwater; and worker protection. A five-hour sales pitch with no safety or law content may not be what the reviewers credit.

Reciprocal Certification and Reciprocal CEUs

If an individual is a certified applicator in another state, that person may be able to attain Oklahoma certification under a reciprocal arrangement. The Board fee is $100 per category (2 O.S. § 3-82(C)(9); OAC 35:30-17-1.2). Reciprocity is not automatic for every state or every category, and it does not erase Oklahoma's business license, insurance, or vehicle-marking duties.

Reciprocal CEU agreements exist between some states. ODAFF posts a CEU Reciprocal Agreement Chart. Procedures, when an agreement is in effect: applicators certified in both reciprocating states who complete a recertification course accredited by either state may request that proof of completion go to the other state, to the extent the credits meet that state's recertification requirements. Do not memorize a partner-state list from a prep blog. Open the current ODAFF chart. Texas last year is not a fact you should invent on an Oklahoma Core item.

Complaints and How CPS Actually Investigates

ODAFF is the lead state agency for pesticide regulation, including alleged pesticide/herbicide misuse. File a PESTICIDE COMPLAINT STATEMENT with:

Damardray Williams
Pesticide Complaint Program Administrator
Oklahoma Department of Agriculture, Food, and Forestry
2800 N. Lincoln Blvd., Oklahoma City, OK 73105
Phone: 405-522-5981
Email: damardray.williams@ag.ok.gov

Once received, the complaint gets a number and a field inspector. You receive confirmation with the inspector's name and the number. The inspector contacts the complainant within three to four days to schedule. The inspection includes a narrative, photos, and samples as needed. The inspector does not estimate monetary losses. Sources that might have been involved are contacted. After the program administrator completes the investigation, the complainant is notified of the final action.

The report is subject to the Oklahoma Open Records Act. Copies are provided upon written request that references the complaint number, through the Public Records Center or the Office of General Counsel at the same Lincoln Boulevard address.

2 O.S. § 3-82(N) and OAC 35:30-17-7: upon a written complaint, the Board notifies the complainant of receipt and status within two (2) working days, and notifies the person complained against within two (2) working days. Landowners or operators may also be notified. The complainant is notified in writing within seven (7) working days after resolution.

Enforcement tools remain those in § 3-86: license or certificate action after notice and hearing; administrative penalty $100 to $10,000 per violation; misdemeanor $100 to $10,000 and/or 30 days to one year in the county jail. Use inconsistent with labeling is separately called out as unlawful and a misdemeanor unless the Board gave prior written approval. Do not quote a revoked first/second/subsequent dollar table as if it were 2026 law.

Unwanted Pesticide Disposal

2 O.S. § 3-82.1 created the Unwanted Pesticide Disposal Fund. A portion of pesticide registration revenue (the statute dedicates $300,000 annually from label fees) supports the program. ODAFF operates an Unwanted Pesticide Disposal Program. That is the legal leftover-product path — not a ditch west of Guymon and not a burn barrel. Collection dates, eligible materials, and packing rules are Chapter 12 material. For this chapter, know the program exists under ODAFF and that dumping is not a recordkeeping solution.

Scenario: the 3a CEU cram in year five

A still-current 3a applicator in Oklahoma City skipped years two through four, then tries to take 20 CEUs in December of the recertification year. Max 10 in any one year, and credits must appear in at least three of five years. The cram fails both counting rules. Phase II within 12 months of expiration is the remaining path; miss that window and Phase I, Phase II, and any practical come back.

Scenario: a drift complaint in Kiowa County

A landowner files a PESTICIDE COMPLAINT STATEMENT after a May application. CPS assigns an inspector who arrives in three to four days, photographs, and samples. The landowner asks "what's my crop worth?" The inspector does not estimate monetary losses. If the landowner later wants a civil crop-damage action, § 3-82(H) still has its own 90-day / 25% harvested written-complaint and access rules. Open-records copies require a written request with the complaint number — not a verbal ask at the tailgate.
