Getting Certified

What do I study for the exam?

Commercial, Noncommercial, and Public Applicators--To become certified as a commercial pesticide applicator, a person must pass both a 50 question, closed-book exam over the Iowa Core Manual, and a 35 question exam specific to the categories for which he or she needs to be certified to do the job. All manuals are available from the Extension Distribution Center.

Certified Handlers--To become certified as a certified handler, a person must pass a 50 question, closed-book exam over the Certified Handlers Manual.

Where can I take the exam?

Pesticide applicator certification exams are available at many community colleges throughout Iowa. More information on dates and locations can be found on Pesticide Applicator Testing Dates page of the Iowa Department of Agriculture and Land Stewardship website.

Fees for Certifiation

Fees are payable to IDALS and cover your 3 year certification. For any questions about examinations or fees, please contact the Pesticide Bureau, IDALS, at 515-281-8591.

  • $75 for Commercial Applicators

  • $15 for Public Applicators

How do I maintain my certification?

Recertification by Exam

Recertify by passing exams, [covering the Iowa Core manual and appropriate category manual(s)] every 3 years. Exams for commercial recertification are available at community college locations throughout Iowa. If an applicator fails an exam the exam may be retaken, but only once per day. Successful passing of the exams and the submission of the appropriate fee to IDALS completes the recertification-by-exam process.

Recertification by Continuing Instruction Course (CIC)

For commercial applicators, C-CICs are offered on a calendar-year basis.

C-CICs are presented in the following formats: live programs and prerecorded blu-ray discs. The following programs are available as statewide video programs with fixed presentation dates: Commercial Agricultural Weed, Insect and Plant Disease; Ornamental & Turf Applicators; Roadside, Forest and Aquatic Pest Management; Fumigation; Seed Treatment; Certified Handlers; Mosquito and Public Health Pest Management; and Pest Control Operators.

Applicators needing Aerial Applicator certification and those needing Greenhouse and Ornamental Applicator certification need to contact their local extension office to arrange a time to watch these C-CIC programs.

Category 1D (Fruit and Vegetable) is available live once a year at the Iowa Fruit and Vegetable Growers Conference, usually in January.

Also, please note recertification by video C-CIC in the county extension is not offered in 1E (Animal Pest Control) and 7E (Wood Preservatives). Recertification in these categories are TEST ONLY.

If C-CICs are missed in one or more years of their three-year cycle, the applicator is required to take the certification exam(s) to renew his or her certification. C-CICs cannot be “made up” if an applicator forgets to attend in a given year, nor can an applicator attend two C-CICs in one year to cover future years’ requirements.

Multiple Category Commercial Pesticide Recertification

Applicators who are certified in more than one category may recertify by examination for some categories and by attending a C-CIC for others. Applicators who choose to maintain their certification by attending an IDALS approved C-CIC must attend a program during each year their certification card covers, including the year they passed the exam (if certification occurs prior to October 1).

Fees for Attending a Commercial Pesticide Applicator Continuing Instructional Course (C-CIC)

There is a $35 fee for attending a C-CIC for all categories except Pest Control Operators. The fee for the Pest Control Operators C-CIC is $60. If you register less than seven days before the C-CIC scheduled date there could be a $10 late registration fee, please check with your local extension office for their policy.
