The New York pesticide applicator core exam is a 50-question, 90-minute, closed-book test administered by the New York State Department of Environmental Conservation. To pass, you need 35 of the 50 correct overall (70%) and at least 7 of 10 correct on the label questions specifically. The content is drawn from FIFRA and the federal pesticide regulations in Title 40 of the Code of Federal Regulations.
How many questions are on the core exam?
The core exam has 50 multiple-choice questions. The time limit is 90 minutes, and the exam is closed book: you cannot bring the training manual, notes, or any reference material into the room.
The questions are drawn from five topic areas. Label comprehension is the only area with its own mandatory sub-score (see below); the rest contribute to the 35-question overall threshold.
What is the pass mark?
You need two things at the same time to pass:
- Overall: at least 35 of the 50 questions correct (70 percent).
- Label rule: at least 7 of the 10 label-reading questions correct.
Both must be met in a single sitting. If you score 36 overall but only 6 on the label questions, you fail. If you score 7 on label questions but only 34 overall, you also fail.
This two-part threshold reflects how the law views label compliance: under FIFRA, using a pesticide in a manner inconsistent with its labeling is a federal violation. The DEC therefore requires demonstrated label-reading competence as a separate condition of certification, not just a contribution to an overall score.
What topics does the exam cover?
The core exam draws from five areas, all grounded in public federal law:
- Pesticide laws and regulations (12 of the 50 questions in our practice mock): FIFRA itself, what counts as a restricted use pesticide, the certification and recertification system under 40 CFR Part 171, categories of certified applicator, supervision of non-certified applicators, and recordkeeping requirements.
- Label and labeling comprehension (10 questions, with the 7-of-10 mandatory rule): required label content under 40 CFR Part 156, signal words (Danger/Poison, Warning, Caution), use directions and restrictions, and why the label is the law.
- Safety, PPE, and worker protection (10 questions): toxicity and exposure, personal protective equipment requirements, first-aid procedures, safe storage and disposal, and the Worker Protection Standard (WPS) under 40 CFR Part 170.
- Environmental protection (10 questions): pesticide drift (and why larger spray droplets reduce it), runoff, leaching, weather considerations, and protecting non-target organisms including pollinators and aquatic species.
- Pests, pesticides, equipment, and application (8 questions): correctly identifying the target pest before selecting a product, pesticide formulations, calibrating application equipment, and choosing appropriate application methods.
All five areas are based entirely on FIFRA (7 U.S.C. 136 et seq.) and the Code of Federal Regulations, Title 40, which are public-domain United States federal laws.
Who needs to take the core exam?
Any person seeking to become a certified commercial pesticide applicator in New York must first pass the core exam. The core covers the knowledge that applies across all pesticide use, regardless of which category or categories of work the applicator will go on to do. Passing the core is the prerequisite before sitting any category-specific exam.
Uncertified persons working under the direct supervision of a certified applicator are not required to pass the exam themselves, but the certified applicator is responsible for their actions.
How is the exam scored, and what happens if you fail?
The DEC sets the scoring: 35 correct overall and 7 of 10 on the label section. Scores are reported after the exam sitting; the DEC administers the exam at authorized testing sites in New York.
If you do not pass, you may retake the exam. The DEC determines the waiting period and any limits on retake attempts; check the current DEC pesticide certification program page for the rules in effect when you sit.
What is the best way to prepare?
Because the label questions carry a mandatory sub-score, drilling label comprehension is not optional, even for candidates who are strong in the law and safety sections. A score of 8 or 9 on the other four areas counts for nothing if label reading falls below 7.
The practice app below includes 756 practice questions and 304 flashcards covering all five topic areas, with a timed 50-question mock that enforces both the 70% overall threshold and the 7-of-10 label rule so you can gauge real readiness before the exam day.
