- Passing score is 70% on the National Core Exam plus your category exam.
- Metro testing costs $55 per exam; limited NMDA staff testing costs $20 per exam.
- Wait at least 48 hours after NMDA application approval before scheduling a Metro exam.
- All exams and licensing steps must finish within 60 days of the original application under 21.17.50 NMAC.
What This Cheat Sheet Covers
This is a one-page reference built specifically for the New Mexico Commercial Pesticide Applicator Core Exam administered under the authority of the New Mexico Department of Agriculture (NMDA), Agricultural and Environmental Services, Pesticide Compliance program. It is not a substitute for full preparation - for that, work through our NM-PEST Study Guide 2026 and the domain-by-domain breakdown in the NM-PEST Exam Domains 2026 guide. Instead, treat this page as the quick-reference sheet you skim the night before scheduling, and again the morning of your test, to make sure no fee, deadline, or domain slipped your mind.
Everything below reflects the current 21.17.50 NMAC rule that replaced the prior version effective October 7, 2025, so if you studied from older materials, double-check dates and dollar figures against what's listed here.

The Ten Domains, Condensed
The exam is built on the federal commercial-core competencies in 40 CFR 171.103(c), used here as a study framework rather than a percentage-weighted New Mexico blueprint. That means there's no official "this domain is worth 15% of the exam" breakdown - you need working knowledge across all ten. Here they are in the order they're typically studied.
Domain 1: Label and Labeling Comprehension
Reading and interpreting product labels correctly is the backbone of the whole exam.
- Signal words, precautionary statements, and use-site restrictions
Domain 2: Safety
Covers personal protective equipment, exposure routes, and emergency response basics.
- PPE selection tied to label REI and hazard statements
Domain 3: Environment
Focuses on protecting water, soil, air, and non-target organisms during and after application.
- Drift, runoff, and groundwater contamination avoidance
Domain 4: Pests
Pest identification and biology across categories relevant to New Mexico's climate and cropping systems.
- Life cycles that determine timing of control measures
Domain 5: Pesticides
Chemical classes, formulations, modes of action, and resistance concepts.
- Matching formulation type to target site and equipment
Domain 6: Equipment
Calibration, maintenance, and appropriate equipment selection for different application scenarios.
- Calibration math and nozzle/sprayer selection logic
Domain 7: Application Methods
How to apply product correctly given weather, site, and target pest constraints.
- Choosing method based on label directions and site conditions
Domain 8: Laws and Regulations
Federal and New Mexico-specific rules governing licensing, use, and enforcement.
- 21.17.50 NMAC provisions on licensing and recordkeeping
Domain 9: Responsibilities of Supervisors of Noncertified Applicators
What a certified applicator owes to workers operating under their supervision.
- Training, instruction, and availability obligations
Domain 10: Professionalism
Recordkeeping, communication with clients/employers, and ethical conduct standards.
- Application records must be completed within 24 hours and retained for two years
Key Takeaway
Domain 10's recordkeeping rule - records completed within 24 hours and kept for two years - shows up in both the Core Exam and real-world compliance, so memorize it exactly rather than approximately.
Eligibility Snapshot
Before you can even schedule the Core Exam, NMDA has to approve your application. The full walkthrough lives in our NM-PEST Requirements guide, but the essentials are:
- Two years of pesticide-application experience, or one year plus 20 college credit hours in biological or agricultural sciences
- Proof of financial responsibility through qualifying insurance or a surety bond
- NMDA application approval and an assigned testing identification number before you can schedule anything
Skipping the approval step is one of the most common - and easily avoided - mistakes candidates make. You cannot book a Metro exam the same day your application is approved; NMDA requires a 48-hour buffer first.
Registration, Fees, and Scheduling Math
Once you have your testing identification number and the 48-hour wait has passed, you can schedule. Two testing paths exist:
- Metro testing: $55 per examination, proctored, requires government-issued photo identification
- Limited, prearranged NMDA staff-administered testing: $20 per examination
Public-applicator exemptions apply only to the NMDA staff examination fee - not to Metro charges. Budget accordingly if you're testing both the Core Exam and a category exam, since each is billed separately at whichever venue you use.
For a deeper look at exactly what counts as a passing performance on test day, read the NM-PEST Passing Score guide, and if you're weighing how tough the exam actually feels compared to expectations, the How Hard Is the NM-PEST Exam guide is a useful reality check before you commit to a test date.
Recertification and Recordkeeping
Passing the exam and getting licensed is only the start. The commercial license costs $100 annually and expires every January 31, regardless of when during the year you were issued it - so mark your renewal date the moment you're certified. Annual general recertification requires at least four continuing education units, though specific categories can require additional credits beyond that baseline.
On the recordkeeping side, application records must be completed within 24 hours of the application and retained for two years. This isn't just an exam-day fact - it's an ongoing compliance obligation once you're working in the field.
Final Review Week Plan
If your test date is roughly a week out, don't try to relearn everything - triage by domain difficulty and personal weak spots instead of running a generic study cycle.
Label, Safety, Environment
- Re-read label components (Domain 1) and PPE/exposure rules (Domain 2)
- Review drift, runoff, and non-target protections (Domain 3)
Pests, Pesticides, Equipment
- Drill pest life cycles and identification cues (Domain 4)
- Review chemical classes and calibration formulas (Domains 5-6)
Application, Law, Supervision, Professionalism
- Match application methods to site conditions (Domain 7)
- Memorize 21.17.50 NMAC essentials and recordkeeping timelines (Domains 8-10)
Simulate Test Conditions
- Run a timed practice session on the main practice test site
- Confirm your photo ID and testing ID number are ready for check-in
Running full-length timed sets on our practice test platform before test day helps surface which of the ten domains still need attention, rather than guessing based on how confident you feel.
Metro vs. NMDA Staff Testing
Choosing where to sit for your exam affects both cost and scheduling flexibility.
| Feature | Metro Testing | NMDA Staff-Administered |
|---|---|---|
| Cost per exam | $55 | $20 |
| Availability | Standard scheduling once approved | Limited, prearranged sessions only |
| Wait after approval | At least 48 hours | Set by NMDA arrangement |
| ID requirement | Government-issued photo ID, proctored | Per NMDA session terms |
| Fee exemption for public applicators | Does not apply | Applies |
Most commercial applicants default to Metro simply because slots are more readily available, but if you qualify for NMDA staff-administered testing and can work within its limited scheduling, the fee savings are real.
Who This Exam Opens Doors With
Because the Core Exam is a prerequisite to holding a commercial applicator license in New Mexico, it's the gateway credential employers check for before assigning category-specific work - agricultural crop protection, structural pest control, right-of-way vegetation management, and similar fields. If you're evaluating whether the licensing investment pays off for your career path, the Is the NM-PEST Certification Worth It analysis and the NM-PEST Salary Guide are worth reading alongside this cheat sheet, and browsing current openings via NM-PEST Jobs can give a feel for which categories are in demand locally.

Keep this sheet handy alongside deeper reads like the NM-PEST Pass Rate data breakdown, and run a few timed practice sets on the practice test site before you commit to a testing date - the fee mechanics and 60-day clock leave little room for a do-over.
