What exams should I take?

Farmers and other growers who need a private applicator permit for purposes of purchasing, using, and/or supervising the use of restricted-use pesticides on property that they control, for purposes of producing an agricultural commodity, will need to pass the Core certification test.

Technicians who work for commercial, for-hire pesticide application businesses, and who need a registered technician credential to apply general- or restricted-use pesticides without a certified and licensed supervisor directly on-site, will need to pass the Core certification test. Technicians who apply restricted use pesticides to their employers property only and who need a registered technician credential so that they may conduct their work without a certified and licensed supervisor directly on-site, will need to pass the Core certification test also.

Persons who are interested in becoming certified as commercial pesticide applicators need to pass the Core certification test and at least one Category certification test. Please note that if you are interested in certification in any of Indiana's limited categories, you need to take the Core certification test ONLY.

How can I prepare for my exam(s)?

Core and Category training materials may be obtained from The Education Store. Call 888/398-4636 to order the materials you need or online at: https://mdc.itap.purdue.edu/
 

Or, you may want to register to attend Core or Category training programs offered by Purdue Pesticide Programs. Core and Category training sessions are day-long events with the test administered at the conclusion of training. Call Purdue Pesticide programs at 765/494-4566 for more information.​

What if I want to become certified to do commercial, for-hire lawn care pest control or termite control?

To become certified in Indiana to apply fertilizer or weed, insect and disease control products in for-hire, residential and industrial lawn care situations you must pass the Core certification test and the Category 3b certification test and document proof of turf pest control experience. Experience may be in the form of 90 days of employment as a registered turf technician or attendance at a hands-on, turf training workshop sponsored by Purdue Pesticide Programs. Call 765/494-4566 for workshop information. Please note that there are certain waivers to the experience requirement for for-hire turf pest control applicators including completion of a two- or four-year college turf degree program or holding a license in another category for a period of at least one year. Contact the Office of Indiana State Chemist (OISC) at 765/494-1594 for more information about waivers.

Termite control operators pursuing full certification take Core and Category 7b certification tests and must meet an experience requirement also. The experience requirement for termite control operators is met by attending a mandatory hands-on wood destroying pest control workshop sponsored by Purdue Pesticide Programs. Call 765/494-4566 for information about workshop availability.

Do home inspectors have to be certified to inspect for wood destroying pests?

Persons who inspect, but do not treat, structures for the presence of wood destroying pests must be certified to do so. Persons interested in becoming certified to inspect homes for wood damaging pests must take the Category 12 (Wood Destroying Pest Inspection) certification test and attend a one day mandatory hands-on training sponsored by Purdue Pesticide Programs. Call Purdue Pesticide Programs at 765/494-4566 for more details.

How do I get the appropriate credentials?

Once you have passed your certification tests (and met any necessary experience requirements) you will need to apply to the OISC for the appropriate applicator credentials. Private applicators need a private applicator permit. Registered technicians need registered technician credentials, and commercial applicators require the proper commercial applicator license (for-hire, not-for-hire, or public). Your employer will likely handle the license application for you, but be certain to have the proper credentials before making any treatments. Call OISC at 765/494-1594 for licensing information, forms, fees, etc.

How do I keep my certification current?

Commercial pesticide applicator certification can be renewed by either of two methods: retesting (i.e., retaking the core and/or category exams) or by accumulating continuing certification hours (CCH's). Approved CCH programs can be located at the OISC website: www.isco.purdue.edu.​
