What each practice exam covers
Every Idaho professional applicator must pass the Applicator Core Competency (CO) exam (or competency training), which ISDA describes as general knowledge of pesticides including proper use, disposal, product characteristics, first aid, labeling and laws (IDAPA 02.03.03.100; ISDA Study Material Guide). Each practice exam follows the federal core competencies every certifying agency must test (40 CFR 171.103), plus Idaho law from the Pesticides and Chemigation Act (Idaho Code Title 22, Chapter 34) and ISDA's rules as rewritten effective July 1, 2026 (IDAPA 02.03.03).

Questions
What exam do these practice tests prepare me for?
The Idaho Applicator Core Competency (CO) exam (Idaho State Department of Agriculture). Professional applicators pass the Applicator Core Competency (CO) exam plus at least one category exam, and commercial apprentices take the CO exam (IDAPA 02.03.03.100; ISDA licensing application).
How is the real Idaho Applicator Core Competency exam set up?
The exam is closed book, 70% passes, it may be retaken after one day, and scores stay valid for 12 months; ISDA staff or an authorized agent proctors it (IDAPA 02.03.03.100.03), and ISDA's exam schedule lists ISDA sessions and Metro Institute remote and testing-center sessions. ISDA doesn't publish the number of questions or the time limit.
