Are the exams open or closed book?
The core exam for public/commercial applicators is closed book. This exam's objective is to establish competency in general pesticide safety topics. The category exams are open book as the questions are specific and detailed relating to the category topic. The exams are multiple choice and contain 50 questions. A 70 percent is needed to pass.
In most cases, private applicators only need to take one exam, which is similar to the core exam for public/commercial applicators. However, this exam is open book and contains 75 multiple choice questions. Additional testing is required for private applicators if they intend to use a restricted use fumigant. Be sure to mention this when pre-registering for the exam.
