- Metro Institute charges $60 per exam; the commercial license itself is $76 at issuance and renewal.
- You need 70% or better on Category A Core plus at least one additional category.
- Twelve domains cover everything from labeling to Minnesota-specific licensing law.
- Three test attempts are allowed per licensure period, so prep matters more than retakes.
What This Cheat Sheet Covers
This is a compressed, one-page-style reference for the Minnesota Commercial Pesticide Applicator Core Exam (Category A), administered by the Minnesota Department of Agriculture with computer-based testing delivered through Metro Institute. It is not a substitute for full preparation - for that, see the MN-PEST Study Guide 2026: How to Pass on Your First Attempt - but it is the fast-recall sheet you pull out the night before, or during a lunch break at work, to make sure nothing important has slipped through the cracks.
Everything below reflects Category A Core content only. If you're stacking a specific category on top of Core, you'll need supplemental study beyond this page, but the mechanics of registration, scoring, and renewal apply across every commercial license track in Minnesota.
Exam Mechanics at a Glance
Before you memorize a single label rule, lock in the logistics. Confusion about fees, attempts, or format costs candidates more points than people realize because it eats into confidence and time management on test day.

The 12 Domains in One Scan
Category A Core is organized into twelve content domains. You don't need to guess what's on the exam - the domains are published, and each one deserves a distinct block of review time. The MN-PEST Exam Domains 2026: Complete Guide to All 12 Content Areas covers each in depth; this section is the compressed version.
Domain 1: Pest Management
Integrated pest management principles, pest identification basics, and decision-making around when treatment is actually warranted.
- Know the difference between prevention, suppression, and eradication strategies
Domain 2: Federal Pesticide Laws and Regulations
FIFRA framework, EPA registration process, and how federal law sets the floor that state law builds on.
- Understand restricted-use vs. general-use classifications
Domain 3: Pesticide Labeling
Reading and interpreting label sections - signal words, directions for use, restrictions, and precautionary statements.
- The label is legally enforceable; questions test your ability to find specific clauses quickly
Domain 4: Pesticide Formulations
Formulation types (liquids, granules, dusts, baits) and how formulation affects handling, mixing, and application choices.
- Match formulation abbreviations to their full names and typical use cases
Domain 5: Pesticide Hazards and First Aid
Toxicity categories, exposure routes, and appropriate first-aid response before professional help arrives.
- Memorize signal word to toxicity category relationships
Domain 6: Personal Protective Equipment
Selecting and maintaining PPE based on label requirements and exposure risk.
- Know when the label requires more protection than the minimum default gear
Domain 7: Pesticides in the Environment
Movement of pesticides through soil, water, and air, plus factors that increase environmental risk.
- Understand drift, runoff, and leaching as distinct movement pathways
Domain 8: Transportation, Storage, and Security
Safe transport practices, storage facility requirements, and preventing unauthorized access to pesticides.
- Know separation and labeling requirements for storage areas
Domain 9: Emergency or Incident Response
Spill containment, reporting obligations, and immediate actions during an exposure or release incident.
- Sequence of steps matters more than isolated facts here
Domain 10: Planning the Pesticide Application
Site assessment, weather considerations, and choosing the right product and timing before any spraying starts.
- Expect scenario-style questions that combine label info with site conditions
Domain 11: Pesticide Application Procedures
Calibration, application techniques, and equipment operation for accurate, compliant applications.
- Calculator is provided for calibration math - practice using one under timed conditions
Domain 12: Minnesota Pesticide Certification and Licensing Laws and Regulations
State-specific rules layered on top of federal law, including licensing categories and recordkeeping duties.
- This domain is where state-specific detail separates prepared candidates from the rest
Labeling and Laws Quick Hits
Domains 2, 3, and 12 together form a heavy chunk of the exam because label literacy and legal framework questions can appear woven into almost any scenario, not just as standalone items. A few fast reminders:
- Federal law (Domain 2) sets registration and classification baselines; Minnesota law (Domain 12) adds licensing categories, renewal cycles, and state enforcement details.
- Label language (Domain 3) is legally binding - if a question describes a practice that contradicts the label, the label wins every time.
- Signal words appear across both labeling and hazards content, so don't study them in isolation from toxicity categories.
Key Takeaway
Treat Domains 2, 3, and 12 as one interconnected cluster rather than three separate topics - exam questions frequently blend them.
PPE, Hazards, and Environment Crib Notes
Domains 5, 6, and 7 test your ability to protect yourself, your crew, and the surrounding environment. These sections reward memorization of relationships rather than isolated facts:
- Toxicity category → signal word: know which category pairs with which label wording.
- Exposure route → first response: dermal, inhalation, oral, and eye exposure each have distinct immediate actions.
- PPE requirement source: the label dictates minimum PPE, and site conditions can push requirements higher.
- Environmental movement pathway: distinguish drift, runoff, volatilization, and leaching, since each has different mitigation steps.
Application Planning and Procedures Recap
Domains 10 and 11 are where math and judgment meet. Expect calibration calculations (a calculator is provided, so practice using one under time pressure rather than doing mental math you haven't rehearsed), plus questions about weather, drift potential, and site-specific decision-making before and during an application.
Fast Review: Planning Before Application
Before any application, a competent applicator confirms the target pest, checks the label for site and rate restrictions, reviews weather and drift risk, and verifies equipment calibration.
- Sequence questions often test whether you'd check the label before or after selecting equipment - label comes first
Emergency response (Domain 9) often gets tested alongside planning and procedures, since real incidents usually trace back to a planning gap. Reviewing these three domains together - 9, 10, and 11 - tends to be more efficient than studying them in isolation.
Licensing, Renewal, and Retest Rules
Domain 12 content extends beyond the exam itself into what happens after you're certified. Here's the compressed version:
- Annual renewal requires either an approved recertification workshop or category retesting, tied to your license's cycle.
- Category A credit is included automatically within approved recertification workshops - you don't need a separate Core session if the workshop covers it.
- You get three attempts within a licensure period, so plan study time accordingly rather than treating retesting as a casual fallback.
- The $76 renewal fee structure ($50 license fee, $21 ACRRA surcharge, $5 processing fee) repeats every year regardless of whether you retest or attend a workshop.
