What This Cheat Sheet Covers
This is a condensed, one-page-style review of the facts every candidate for the Kentucky Commercial Pesticide Applicator Core Exam needs pinned to memory before test day. It is not a substitute for full preparation - for that, see our KY-PEST Study Guide 2026: How to Pass on Your First Attempt - but it is exactly the kind of quick-scan reference you should reread the night before you test, whether you're sitting the exam through Everblue online proctoring or at a Kentucky Department of Agriculture (KDA) in-person session.
Everything below is specific to the Kentucky Commercial Pesticide Applicator Core Exam administered under KDA authority. If you're still unclear on what the credential even is, start with What Is KY-PEST? or KY-PEST Meaning before diving into logistics.
Registration and Fee Facts
These are the mechanics that trip up first-time applicants - memorize them exactly.

Exam Format at a Glance
Whether you test online through Everblue or in person at a KDA session, the exam is written and proctored - there is no unproctored or take-home version.
- Closed book: The online route is strictly closed book. No personal notes, printed manuals, or reference sheets at your desk.
- Calculator: Online candidates may use only the supplied on-screen calculator. Personal calculators, phones, or physical calculators are not permitted.
- Technical setup: Online testing requires a compatible computer, a working webcam, a microphone, and a single-monitor setup - dual monitors will get you flagged or disqualified.
- Completion window: Once you register online and receive notification, you have 30 days to complete the exam. Miss that window and you'll need to re-register.
- Passing score: 70%. There is no partial credit tier or curve mentioned in KDA guidance - 70% is the line.

The 10 Core Standards of Competency
These are the official content areas defined in 302 KAR 26:020. Every question on the Core exam maps back to one of these 10 domains. Treat this list as your master checklist.

- Pest life cycles and behavior basics
- Integrated pest management concepts
Domain 5: Pesticides
Formulations, modes of action, and how chemical properties affect handling and application decisions.
- Formulation types and their handling implications
- Compatibility and mixing order
Domain 6: Equipment
Application equipment types, calibration basics, and maintenance to ensure accurate, safe delivery.
- Calibration principles and common equipment components
- Cleaning and storage practices
Domain 7: Application Methods
Matching the application technique to the target site, pest, and label instructions.
- Method selection based on label and site conditions
- Weather and timing considerations
Domain 8: Laws and Regulations
Kentucky and federal pesticide law as it governs certification, use, recordkeeping, and enforcement.
- KDA authority and certification categories
- Recordkeeping and reporting obligations
Domain 9: Responsibilities of Supervisors of Noncertified Applicators
What a certified applicator must do when directing uncertified staff performing pesticide work.

Domain 10: Professionalism
Ethical conduct, customer communication, and business practices expected of certified applicators.

Key Takeaway
The University of Kentucky's Pesticide Safety Education Program points to the National Pesticide Applicator Certification Core Manual, third edition (2025), as the study resource aligned to these 10 domains. Use it as your primary text.
License and Renewal Facts
Passing the exam is the start, not the finish line. Kentucky commercial pesticide applicator licenses run on a strict annual calendar.
- Expiration: Every license expires December 31 - regardless of when during the year you were certified.
- CEU requirement: 12 continuing education units are required over the preceding rolling three-year period.
- Category coverage: At least one CEU must be earned in each category you hold - Core CEUs alone won't cover a multi-category license.
- UK's practical deadline: University of Kentucky guidance advises completing CEUs by November 30, giving you a buffer before the December 31 hard expiration.
These renewal mechanics matter even before you sit your first exam, because they shape how you'll plan ongoing training once certified. See KY-PEST Training for continuing education pathways.
A One-Week Cram Timeline
If you're using this cheat sheet in the final stretch before an already-scheduled exam, here's how to sequence a short review week around the 10 domains rather than generic study advice.
Label, Safety, Environment (Domains 1-3)
- Re-read label anatomy: signal words, REI, PHI, precautionary statements
- Review PPE selection tied to specific label language
- Memorize drift and buffer zone basics
Pests, Pesticides, Equipment (Domains 4-6)
- Run through pest categories and IPM logic
- Drill formulation types and mixing order
- Review calibration math using only the on-screen calculator style, since that's all you'll have online
Application, Law, Supervision, Professionalism (Domains 7-10)
- Match application methods to site and weather scenarios
- Review Kentucky's pesticide law framework and recordkeeping duties
- Study supervisor responsibilities for noncertified staff and professional conduct expectations
Full Review and Logistics Check
- Take a full practice test on our practice test platform
- Confirm single-monitor setup, webcam, and microphone if testing online
- Double-check ID matches your registration exactly
This compressed schedule works because it's built around the actual domain weighting of the exam, not a generic study calendar. For a longer runway with more repetition, follow the full plan in the KY-PEST Study Guide 2026: How to Pass on Your First Attempt.
