- Operators need 65% on Core and each category exam; Principals need 70% plus a separate laws exam.
- Initial Core and category exams cost $50 each; reexams cost $35 each; the Operator license itself is $50.
- Retesting waits are 7 days for Operators and 10 days for Principals - plan your calendar around this.
- The Core exam maps directly to six domains under R077-21 Section 8, from operations to pesticide safety.
What This Cheat Sheet Covers
This is a condensed, one-page-style reference for the Nevada Commercial Pest Control Operator Core Exam (NV-PEST), administered through the Nevada Department of Agriculture (NDA). It is built for candidates who already have a study plan underway and need a fast way to confirm they have the right numbers, terms, and domain names memorized before test day. If you haven't built that study plan yet, start with the NV-PEST Study Guide 2026, which walks through a full first-attempt preparation strategy.
This page is deliberately narrow: it does not cover the separate restricted-use-pesticide certification pathway. The Core exam and this site's focus are on the for-hire commercial pest control Operator license and general-use pesticide competency. If you're unsure which license type applies to your situation, review NV-PEST Requirements 2026 before you register.
The Six Core Domains at a Glance
The Core exam reproduces the general-use competency subjects listed in Section 8 of adopted regulation R077-21. These are content areas - competency topics you're expected to know - rather than weighted sections with fixed percentages. For a deep dive into each one, see the NV-PEST Exam Domains 2026 guide.
Domain 1: Operations for Pest Control
Covers the business and procedural side of running a pest control operation for hire.
- Record-keeping expectations tied to licensed work
- Service-related responsibilities of a licensed Operator
Domain 2: An Integrated Approach to Pest Management
Tests understanding of IPM principles as they apply to commercial, general-use pest control decisions.
- Combining monitoring, prevention, and control tactics
- Choosing the least disruptive effective method
Domain 3: Pests
Identification and behavior of pests commonly targeted by licensed operators.
- Recognizing pest categories relevant to general-use control
- Understanding pest biology that drives treatment timing
Domain 4: Recommended Practices for Controlling Pests
Covers accepted methods and techniques for treating identified pest problems.
- Matching control methods to pest and site conditions
- Understanding why certain practices are recommended over others
Domain 5: State and Federal Statutes and Regulations Relating to Pesticides
Legal framework governing pesticide use, licensing, and enforcement in Nevada.
- How NDA oversight applies to licensed Operators
- Distinctions between license types and their obligations
Domain 6: Safety in the Handling and Application of Pesticides
Personal, public, and environmental safety practices required when applying pesticides.
- Safe storage, handling, and application procedures
- Recognizing and responding to exposure risks
Key Takeaway
Because these six domains are content areas rather than weighted sections, don't try to guess a "biggest domain" - study all six thoroughly rather than concentrating effort on assumed high-value areas.
Fees, Passing Scores, and Waiting Periods
Numbers are where candidates lose easy points on quick-reference recall, so memorize these precisely. For a full pricing breakdown, see NV-PEST Certification Cost 2026, and for score specifics, see NV-PEST Passing Score 2026.
| Item | Operator | Principal |
|---|---|---|
| Passing score on Core exam | 65% | 70% |
| Passing score on each category exam | 65% | 70% |
| Additional required exam | None beyond Core + categories | Separate Nevada laws-and-regulations exam |
| Initial Core / category exam fee | $50 each | $50 each |
| Reexamination fee | $35 each | $35 each |
| Minimum wait before retesting | 7 days | 10 days |
| License fee | $50 (individual Operator license) | Varies by category/business licensing |
Operator vs. Principal: Quick Comparison
Confusing Operator and Principal requirements is one of the most common mistakes candidates make when reviewing study materials. Keep this distinction sharp:
| Requirement | Operator | Principal |
|---|---|---|
| Age | Must have reached age of majority | Must have reached age of majority |
| Education/experience prerequisite | Not required | Required |
| Exams required | Core + each requested category | Core + laws-and-regulations exam + each requested category |
| Employment condition | Must be employed by a licensed pest control business and endorsed by its principal | Business-level licensing responsibilities |
Since Operator licensure depends on employment by a licensed pest control business plus endorsement from its principal, most candidates preparing for this exam are already employed or have a pending job offer in the industry - see NV-PEST Jobs for how employment ties into licensure.

Registration & Scheduling Snapshot
Examinations are written and scheduled directly with the Nevada Department of Agriculture. Before you book a date, confirm:
- Whether you're testing as an Operator (Core + categories, 65% passing) or Principal (Core + laws exam + categories, 70% passing).
- Which category exams your intended job role requires you to pass alongside Core.
- That you understand the fee structure: $50 per initial exam, $35 per reexam, plus the $50 Operator license fee once you pass.
- Your retest wait period if you don't pass on the first attempt - 7 days for Operators, 10 for Principals.

Renewal & Continuing Education Checklist
Passing the exam is not the end of the compliance story - license renewal has its own recurring requirement.
- Renewal ordinarily requires 6 approved pest-control continuing-education units completed in the preceding 12 months.
- Principals must include at least 1 unit in laws and regulations among those 6.
- Exemptions exist for first-time licensees who have held the license for less than 12 months.
- Exemptions also apply to qualifying examination-based renewal, where retesting substitutes for CE units.
Key Takeaway
Don't wait until renewal season to check your CE unit count. Track units as you complete them throughout the year so you're never scrambling to hit the 6-unit (or 1-unit laws-and-regs) minimum.
Final-Week Domain Review Plan
If you've already done deep study using the full guide, use your last week before test day to cycle through the six domains in a fixed order rather than reviewing randomly. This isn't a generic study method - it's sequenced to match how the domains build on each other for the Core exam specifically.
Domains 5 & 6 - Regulations and Safety
- Re-read statute and regulation summaries; these underpin every other domain
- Drill pesticide handling and application safety scenarios
Domains 3 & 4 - Pests and Control Practices
- Pair each pest category with its recommended control practice
- Focus on why a practice is recommended, not just what it is
Domain 2 - Integrated Pest Management
- Practice choosing the least disruptive effective method in sample scenarios
- Connect IPM reasoning back to Domains 3 and 4
Domain 1 - Operations
- Review record-keeping and operational responsibilities
- Confirm you know Operator vs. Principal employment and endorsement rules
Full-Length Practice & Weak-Spot Review
- Take a full practice run on the practice test site under timed conditions
- Revisit only the domains where you missed questions
This front-loads the regulatory and safety material because Domains 5 and 6 tend to inform reasoning across the rest of the exam. For more on why the exam feels challenging to some candidates and easy to others, see How Hard Is the NV-PEST Exam?
Common Mix-Ups to Avoid on Test Day
- Confusing passing thresholds: Operators need 65% per exam; Principals need 70%. Don't study to the wrong number.
- Forgetting the Principal-only laws exam: Principals must pass a separate Nevada laws-and-regulations exam in addition to Core and category exams - Operators do not take this separate exam.
- Mixing up reexam and initial fees: $50 for an initial Core or category exam, $35 for a reexam - not interchangeable.
- Assuming domain weighting: The six domains are competency topics from R077-21 Section 8, not percentage-weighted sections, so don't skip any of them assuming they're "minor."
- Overlooking the employment requirement: Operator licensure requires employment by a licensed pest control business and endorsement by its principal - this isn't optional paperwork.
FAQ
Operators need at least 65% on the Core exam and on each requested category exam. Principals need at least 70% on Core, the laws-and-regulations exam, and each category exam.
