1. Understanding the Exam Structure
The pesticide applicator exam has two parts: a core exam (required for everyone) and category-specific exams based on your application area. The core exam typically has 50-100 multiple choice questions with a 70% passing score.
- Private applicators â use RUPs on their own agricultural land
- Commercial applicators â apply pesticides for hire or on non-agricultural property
- Each state administers its own exam, but core content follows EPA guidelines
