- Written passing threshold is 75%, with up to three hours to finish the exam.
- DEEP's exam/retest fee is $200 for up to three categories per registration, plus an Everblue proctoring charge.
- You must test within 90 days of DEEP fee payment and within Everblue's access window; retakes need a 30-day wait.
What This Cheat Sheet Covers
This is a one-page-style reference for the Connecticut Commercial Pesticide Applicator Core Exam, administered under the Connecticut Department of Energy and Environmental Protection (DEEP) Pesticide Management Program, with online written testing delivered through Everblue. If you already worked through a full CT-PEST Study Guide 2026: How to Pass on Your First Attempt, treat this page as the condensed version you skim the night before your session - dates, fees, domain names, and a few facts people consistently mix up.
One structural point worth repeating because it trips people up: since April 2021, DEEP does not run the core-and-safety component as a separate standalone test. It's folded into the same written exam as your category-specific questions. So when people ask "how many exams do I take," the honest answer is that core knowledge shows up woven into whichever supervisory category exam you sit for, not as its own isolated block.
Registration and Fee Facts at a Glance
These numbers come straight from DEEP's own process documentation, and they're the ones people get wrong most often because other unrelated credentials share the same acronym online. For a full breakdown, see CT-PEST Certification Cost 2026: Complete Pricing Breakdown, but here's the compressed version:
| Item | Amount / Detail |
|---|---|
| DEEP exam or retest fee | $200, covers up to three different supervisory categories per registration |
| Everblue proctoring charge | Separate fee, in addition to the DEEP exam fee |
| Certification issuance / five-year renewal | $285 |
| Written passing score | 75% |
| Time allowed | Up to three hours |
| Minimum age | 18 |
| Testing window | Within 90 days of DEEP fee payment, and within the Everblue access window |
| Retake wait (same category) | At least 30 days |
Key Takeaway
Pay your DEEP fee only when you're ready to schedule - the 90-day clock starts at payment, not at registration approval, and the Everblue proctoring fee is billed separately from the $200 DEEP charge.
The Eleven Domains, Fast
The eleven content lines tested reproduce the National Core Manual chapter headings that UConn links for study purposes. A full walkthrough with study emphasis for each lives at CT-PEST Exam Domains 2026: Complete Guide to All 11 Content Areas. Here's the fast-recall version:
Domain 1: Pest Management
Integrated pest management concepts, thresholds, and non-chemical control tactics candidates need before reaching for a pesticide.
- Know when IPM principles override a straight chemical-treatment answer choice.
Domain 2: Federal Pesticide Laws and Regulations
FIFRA framework, registration categories, and how federal law interacts with Connecticut-specific statutes and regulations.
- Expect questions distinguishing federal minimums from state-added requirements.
Domain 3: Pesticide Labeling
Reading and interpreting label sections - signal words, precautionary statements, restricted-entry intervals, and directions for use.
- "The label is the law" phrasing shows up in scenario questions, not just definitions.
Domain 4: Pesticide Formulations
Differences between liquids, dusts, granules, and other formulation types, plus how formulation affects handling and application choice.
- Match formulation abbreviations (like EC, WP, G) to their handling implications.
Domain 5: Pesticide Hazards and First Aid
Toxicity categories, exposure routes, and appropriate first-aid response before professional medical help arrives.
- Signal word-to-toxicity category mapping is a recurring question style.
Domain 6: Personal Protective Equipment
Selecting and maintaining PPE based on label requirements and exposure risk, not personal preference.
- Study which PPE items the label mandates versus what's simply good practice.
Domain 7: Pesticides in the Environment
Movement of pesticides through soil, water, and air, plus DEEP's pollinator and groundwater supplements referenced in study materials.
- Groundwater protection scenarios often connect directly to Connecticut-specific supplemental guidance.
Domain 8: Transportation, Storage, and Security
Safe transport practices, storage facility requirements, and security measures preventing unauthorized access to pesticides.
- Expect questions on compatible storage and preventing cross-contamination.
Domain 9: Emergency or Incident Response
Spill containment, reporting obligations, and immediate response steps when something goes wrong during handling or application.
- Sequence-of-action questions test whether you know the correct order of response steps.
Domain 10: Planning the Pesticide Application
Pre-application decisions: site assessment, weather considerations, and selecting the right product and method for the job.
- Watch for scenario questions requiring you to reject an application due to conditions like wind or proximity to water.
Domain 11: Pesticide Application Procedures
Correct application techniques, calibration basics, and following label-directed procedures during actual treatment.
- Calibration math and equipment-specific procedure questions cluster here.
If you're unsure which of these deserve more of your remaining study hours, How Hard Is the CT-PEST Exam? Complete Difficulty Guide 2026 breaks down where candidates typically lose the most points.
Format, Timing, and Passing Score
The written exam is delivered online through Everblue and requires a supported computer, webcam, microphone, and proctoring software - test this setup before your scheduled window, not the morning of. You get up to three hours to complete the written portion, and you need 75% correct to pass. For the exact mechanics of how that score is calculated and what it means for guessing strategy, see CT-PEST Passing Score 2026: Exactly What You Need to Pass.
If you don't pass on the first attempt, a same-category retake requires waiting at least 30 days before you can sit again. That gap is meant for real review, not a quick reread - use it to isolate which domains cost you the most points and rework those specifically rather than restudying everything evenly.
The Oral Exam Piece Most People Forget
Passing the written exam isn't the finish line for most supervisory categories. Most categories also require an in-person oral examination in Hartford, typically running 20 to 30 minutes. Candidates who only prep for the online written test sometimes get caught off guard by this step, so build it into your planning from the start rather than treating it as an afterthought once the written score clears.
The oral component tends to probe practical judgment - how you'd respond to a described field scenario, how you'd interpret a label direction out loud, or how you'd sequence an emergency response. It rewards candidates who can explain reasoning clearly, not just recognize correct answers on a multiple-choice screen.
Study Sources DEEP Actually Wants You to Use
DEEP points candidates toward a specific set of materials, and leaning on anything else wastes time. Prioritize:
- Your category-specific study manual (the one matching the supervisory category you're testing for)
- Connecticut pesticide statutes and regulations
- DEEP's pollinator protection supplement
- DEEP's laundry-safety supplement (handling and cleaning contaminated clothing/equipment)
- DEEP's groundwater supplement
- The National Core Manual chapters linked through UConn, which map directly to the eleven domains above
DEEP's supervisory guidance was last updated July 20, 2026, so confirm you're studying the current version of any linked manual or supplement rather than an older cached copy. If you want a structured walkthrough of how to sequence these materials rather than reading them cover to cover, CT-PEST Study Guide 2026: How to Pass on Your First Attempt lays out a fuller plan.
Key Takeaway
Don't skip the three DEEP supplements (pollinator, laundry-safety, groundwater) - they're called out specifically alongside the core manual and category study material, which signals they're fair game on the written exam.
Renewal and Continuing Education Facts
Passing the exam and completing the oral component isn't the end of the obligation - certification runs on a five-year cycle. Renew by January 31 of the expiration year, with 12 continuing-education credits required per category, plus submission of required annual pesticide-use summaries and payment of the applicable $285 fee. Missing the January 31 deadline or falling short on CE credits can force you back through examination rather than a simple renewal.
This renewal structure matters when you're weighing whether certification is worth pursuing in the first place - ongoing CE and reporting obligations are part of the real cost of holding the credential long-term, not just the upfront exam fee. See Is the CT-PEST Certification Worth It? Complete ROI Analysis 2026 for how that tradeoff plays out against what employers typically pay certified supervisors, covered in more depth at CT-PEST Salary Guide 2026: Complete Earnings Analysis.
A Compressed One-Week Review Plan
If you're past the deep-study phase and just need a final tune-up before your Everblue session, spread your remaining hours across the domains that carry the heaviest scenario-based weight rather than reviewing everything equally.
Labeling, Laws, and Hazards
- Reread Pesticide Labeling and Federal Pesticide Laws and Regulations sections
- Drill signal-word-to-toxicity mapping under Pesticide Hazards and First Aid
Environment and Storage
- Review Pesticides in the Environment alongside DEEP's groundwater and pollinator supplements
- Cover Transportation, Storage, and Security compatibility rules
Application Practice and Oral Prep
- Work through Planning the Pesticide Application and Application Procedures scenarios
- Rehearse answering scenario questions out loud for the Hartford oral component
Full Review and Logistics
- Confirm webcam, microphone, and proctoring software work before test time
- Recheck your 90-day testing window and category-specific manual for last details
If you're prepping with practice questions to test recall speed rather than just rereading notes, run a full timed set through the main practice test platform so you get comfortable pacing yourself across all eleven domains within the three-hour window.
Common Mix-Ups to Avoid Before Test Day
A few recurring confusion points worth clearing up before you walk into (or log into) your exam:
- Core isn't a separate exam. Since April 2021, core-and-safety content is combined with category questions - don't schedule expecting a standalone core test.
- Fee scope. The $200 DEEP fee covers up to three categories per registration, but the Everblue proctoring charge is billed separately, so don't assume $200 is the full cost.
- Two testing clocks. Both the 90-day-from-payment window and Everblue's own access window apply - plan around the tighter of the two.
- The oral exam is real and in-person. Most categories require it in Hartford; don't assume a passing written score means you're fully certified yet.
- This isn't the Junior Operator exam. If you're researching a different track by mistake, your requirements and fees will look different from what's listed here.

FAQ
No. Since April 2021, DEEP has combined the core-and-safety component with category-specific written questions rather than running it as a standalone test.
You need 75% to pass, and you're given up to three hours to complete the written exam through Everblue's online proctored system.
The DEEP exam or retest fee is $200 and covers up to three different supervisory categories per registration, plus a separate Everblue proctoring charge. Certification and each five-year renewal cost $285.
Most categories require an additional in-person oral examination in Hartford, usually 20 to 30 minutes, before full certification is issued.
Same-category retakes require waiting at least 30 days, and you must still test within your 90-day-from-payment window and Everblue's access window.
