- The exam is 100 questions, closed-book, 2 hours, and requires 70% to pass.
- You need a TDA eligibility letter and account number before you can even schedule.
- The $64 exam fee is separate from the $200 commercial applicator license fee.
- Study from AES-5073 (General) and AES-5056 (Laws and Regulations) - no other source is official.

Registration Sequence Before Test Day
Unlike exams you can register for the moment you decide to study, TX-PEST has a required paperwork sequence that has to happen in order. Skip a step and you simply cannot book a seat.
- Apply to TDA. This is your formal application to become a commercial applicator.
- Pay the $200 commercial applicator license fee. This is separate from - and paid before - the $64 exam attempt fee.
- Receive your TDA eligibility letter and account number. This document is your proof that you're cleared to test.
- Schedule with Metro Institute. Only after you have the eligibility letter can you book the in-person, computer-based session.
- Pass the Agricultural General Standards exam and at least one category exam. Licensure requires both - General alone doesn't complete the process.
For a deeper look at what "eligible" actually means and common reasons applications get delayed, see TX-PEST Requirements 2026: Eligibility, Prerequisites & How to Qualify. If you're trying to figure out when to actually sit for it once you're eligible, TX-PEST Exam Dates 2026 covers scheduling windows and deadlines.
Key Takeaway
Budget for two separate payments: $200 to TDA for the license application, and $64 to Metro Institute (or via TDA's process) for each exam attempt. Don't confuse the two when planning your total cost.
All 22 Domains in One Pass
The General Standards exam draws from 22 content domains. None of them are described publicly with individual weightings, so treat every domain as fair game rather than skipping the ones that sound minor. Here's the full list in the order most candidates find logical to study:
Domains 1-3: Regulatory Foundation
Pesticide Applicator Certification and Licensing, State Laws and Regulations, and Federal Pesticide Laws form the legal backbone of the exam. Expect questions on who can apply which products, what records TDA requires, and how state rules interact with federal statutes like FIFRA.
- Know the difference between certified and licensed status
- Understand supervisory requirements for noncertified applicators
Domains 4-6: Toxicity, Residue, and Ecology
Toxicity of Pesticides, Residue/Tolerance/Registration, and Ecology and Environmental Protection test your understanding of how pesticides behave in the body and in the environment after application.
- Signal words and their relationship to toxicity categories
- How tolerances and registration status affect legal use
- Environmental fate concepts: runoff, leaching, drift into sensitive areas
Domains 7-9: Safety and Poisoning Response
General Safety Precautions, Protective Equipment and Personal Safety, and Pesticide Poisoning and First Aid cluster together because they're all about protecting the applicator and bystanders.
- Match PPE requirements to specific label statements
- Recognize symptoms tied to different poisoning routes (dermal, inhalation, oral)
- Know immediate first-aid steps before professional care arrives
Domain 10: Integrated Pest Management
IPM shows up not just as its own domain but woven into label and application questions. Understand the hierarchy of prevention, monitoring, and treatment thresholds before resorting to chemical control.
Domains 11-14: Pests, Pesticide Types, Labels, and Formulations
Pests, Types of Pesticides, The Label, and Formulations are where a lot of memorization work happens.
- Label sections: signal words, precautionary statements, use directions, re-entry intervals
- Formulation abbreviations (EC, WP, G, etc.) and what they imply about handling
- Basic pest identification categories relevant to commercial application
Domains 15-18: Mixing, Math, Equipment, Calibration
Filling and Mixing Practices, Calculations for Mixing Pesticides, Equipment, and Calibration are the most math-heavy domains on the exam.
- Dilution and mixing ratio problems
- Calibrating sprayers to deliver a target rate per acre
- Matching equipment type to application scenario
Domains 19-22: Application Conditions and Recordkeeping
Weather-Wise Application, Disposal, Storage, and Record Keeping and Liability round out the list - these are often underestimated because they feel procedural, but they're tested just like everything else.
- Wind speed and temperature inversion effects on drift
- Container disposal and triple-rinse procedures
- What records must be kept and for how long, plus liability exposure for noncompliance
For narrative explanations of each domain with example question angles, see the TX-PEST Exam Domains 2026: Complete Guide to All 22 Content Areas. If you're still deciding how much time this whole process will actually take you, How Hard Is the TX-PEST Exam? Complete Difficulty Guide 2026 gives a realistic assessment based on the domain spread above.
The Two Manuals You Actually Need
There is no ambiguity here: the exam is built around two Texas A&M AgriLife publications.
- AES-5073 - General manual. Covers the technical content behind most of the 22 domains: toxicology, safety, equipment, formulations, IPM, and pest biology basics.
- AES-5056 - Laws and Regulations manual. Covers Domains 1-3 in depth, plus the recordkeeping and liability material in Domain 22.
Calculations, Calibration, and the Calculator
Domains 16 and 18 - Calculations for Mixing Pesticides and Calibration - are where candidates without a math background tend to lose the most points. The good news: you're given a four-function calculator and scratch paper during the test, so you're not doing long division by hand.
Practice these problem types until they're automatic:
- Converting a label rate (oz/acre or pt/100 gal) into the actual amount needed for your tank size
- Calculating output per nozzle to hit a target gallons-per-acre rate
- Adjusting mixes for partial tanks or split applications
- Working backward from spray swath width and travel speed to confirm calibration is correct
These questions are typically presented as short word problems rather than pure formulas, so reading comprehension matters as much as arithmetic. Misreading units (ounces vs. pints, acres vs. square feet) is the most common error candidates report.
The Label, Safety, and PPE Cluster
If you had to pick the single highest-value domain to over-prepare, it would be Domain 13, The Label. Label literacy threads through Domains 4, 7, 8, 9, 14, 19, 20, and 21 - meaning label-reading skill pays off across roughly a third of the exam's content areas.
What "reading the label" actually means for this exam
You're expected to locate and interpret specific sections quickly: signal word, active ingredient percentage, precautionary statements, PPE requirements, re-entry interval, first-aid statements, storage and disposal instructions, and environmental hazard statements.
- Practice with real specimen labels, not just summaries
- Memorize which signal word corresponds to which toxicity category
- Know where re-entry interval and PPE information typically appear on a label layout
A Compressed Final-Week Plan
If you've already worked through the full manuals and just need a short structured review before test day, this compressed plan sequences the highest-yield domains first.
Laws, Licensing, and the Label
- Review Domains 1, 2, 3, and 13 from AES-5056 and AES-5073
- Drill signal words, PPE statements, and re-entry intervals from sample labels
Math and Equipment
- Work calibration and mixing-ratio problems (Domains 16 and 18) using a four-function calculator, same as test day
- Review equipment types and matching scenarios (Domain 17)
Safety and Environment
- Cover toxicity categories, first aid, PPE, and poisoning symptoms (Domains 4, 7, 8, 9)
- Review ecology, drift, and weather effects (Domains 6 and 19)
Remaining Domains
- Cover pests, formulations, IPM, disposal, storage, and recordkeeping (Domains 10, 11, 12, 14, 20, 21, 22)
Full Review and Rest
- Skim both manuals' summary sections
- Confirm your eligibility letter and account number are in hand for scheduling
This is a compression of a longer-term plan - if you have more than a week available, the full TX-PEST Study Guide 2026: How to Pass on Your First Attempt lays out a more gradual schedule. And if you want to double-check the exact score threshold you're working toward, TX-PEST Passing Score 2026: Exactly What You Need to Pass breaks down what 70% means in practical terms for a 100-question test.
After You Pass: Recert and Renewal
Passing the General Standards exam and at least one category exam gets you licensed, but the work doesn't stop there. Commercial and noncommercial applicators must recertify annually with 5 continuing education units (CEUs).
Also remember that your exam score itself is only valid for 12 months. If you pass General Standards but delay completing a category exam past that window, you may need to retest. This detail trips up more candidates than the exam content itself.

FAQ
No - it's a review and orientation tool, not a substitute for AES-5073 and AES-5056. Use it to check your recall after studying the manuals, not instead of them.
You don't need to recite domain titles, but you do need working knowledge of the content each one covers, since questions are drawn from across all 22 areas without published weighting.
You can attempt again by paying the $64 fee for another sitting. Since scores are valid for 12 months, plan your retake and any category exam within that window.
No - a four-function calculator is provided at the testing center along with scratch paper, so you don't need to bring your own.
No. Licensure requires passing the General Standards exam plus at least one category exam, in addition to completing the TDA application and license fee steps.
