How do you get an Oklahoma pesticide applicator license?
- Order study materials from Oklahoma State University (OSU) Central Mailing Service, or private packets from many county extension offices.
- Book with Pearson VUE online or by phone at least 48 hours ahead. Walk-ins aren’t accepted.
- Pass the core exam first. You then have a year to pass a category exam. Categories 11b, 12a and 12b have 25 questions in 50 minutes.
- Categories 7a General Pest, 7b Structural and 7c Fumigation also need a practical at OSU in Stillwater within 12 months.
- Private applicators and service technicians take their own exam without the core.

Recertification on a five-year schedule
Each category recertifies on a fixed five-year schedule, not from the date you were certified. Each cycle ends December 31 of its fifth year, as ODAFF’s CEU table shows, and recertification opens September 1 of that year. Category totals run from 5 to 20 continuing education units (CEUs), prorated if you join late; private applicators need 20. CEUs earned in the year you’re certified don’t count. You can retest for $92 instead.
Business licenses run October 1 to September 30 for company names starting with a number or A to L, and January 1 to December 31 for M to Z.
