What each practice exam covers

Arizona gives the National Pesticide Applicator Certification Core Exam, and its rule has the core test the federal core standards (A.A.C. R3-8-211; 40 CFR 171.103(c)). Mississippi, Oklahoma, Iowa and North Dakota set their core exams by the same federal standards. Those standards include knowledge of applicable state laws (40 CFR 171.103(c)(8)), so those four exams may also ask about state law, and this practice exam has none. Each practice exam follows the federal core competencies, plus federal certification, restricted use pesticide and Worker Protection Standard rules.
