H Exam Dates 2026: Testing Windows, Deadlines & Scheduling

Why There Is No Single National Exam Calendar

Many certification exams run on fixed testing windows through a central vendor. The Hazardous Materials (H) endorsement does not work that way. There is no single national Pearson VUE, PSI or Prometric appointment system for the H exam, and no published list of nationwide testing windows you can mark on a calendar.

The H endorsement is a federal standard delivered locally. The Federal Motor Carrier Safety Administration (FMCSA) sets the knowledge requirements in 49 CFR 383.121, but your state's Driver Licensing Agency administers the knowledge test and issues the endorsement on your commercial driver's license. That means "exam dates" in practice are the appointment slots, walk-in hours and testing rules of the specific state office or approved third-party tester where you apply.

If you are still deciding whether this endorsement fits your career, the What Is H Certification? overview and the H Requirements guide explain eligibility before you start worrying about scheduling.

Who Controls Your Date: State, TSA and Training Provider

Three separate parties can each delay or accelerate your H endorsement. Knowing which one controls which step prevents the most common scheduling mistake: booking a test before the prerequisites are actually done.

Because states administer the test under federal standards, details such as whether the test may be written, verbal or automated can vary in delivery even though federal rules permit all three formats under 49 CFR 383.133. Always check the administering state's own instructions through the FMCSA states directory and your state's current CDL manual.

The Order Things Must Happen In

Candidates lose weeks by doing steps out of order. A workable sequence for a first-time applicant looks like this:

1. Confirm CDL eligibility. You need appropriate CDL eligibility, identity and citizenship or immigration documentation, and to satisfy driver qualification requirements. See the H Requirements guide for the full checklist.
2. Complete theory-only ELDT. Enroll with a provider listed on the FMCSA Training Provider Registry and finish the hazardous materials theory curriculum, including the theory assessment.
3. Start TSA enrollment. Begin the security threat assessment early, because clearance is separate from your exam and can run in parallel with study.
4. Prepare for the state knowledge test. Study your state's current CDL manual and practice with question styles that match the five federal knowledge areas.
5. Schedule and take the knowledge test. Book through your state, bring required documents, and aim for at least 80% correct.
6. Receive the endorsement. The state issues the H endorsement on your CDL once all requirements, including TSA clearance, are satisfied.

Notice that the written exam is not the longest-lead item. The steps most likely to set your finish date are ELDT completion and TSA processing, so start those first and let the exam appointment follow.

ELDT Timing: The Step That Gates Your Test Date

Since February 7, 2022, first-time H applicants must complete theory-only Entry-Level Driver Training through a provider on the FMCSA Training Provider Registry before taking the state knowledge test. This is a hard gate, not a recommendation. A state generally cannot let you sit the H knowledge test as a first-timer until your provider has reported your completion.

A few facts shape how you plan around this requirement:

• There is no federal minimum number of theory-training hours. What matters is that every prescribed topic is covered and that you pass the ELDT theory assessment with at least 80%.
• States may require more than the federal minimum, so confirm local expectations before choosing a provider.
• The curriculum is defined in Appendix E to Part 380. It is a separate document from the five federal exam knowledge areas, so completing ELDT and studying for the state test are related but distinct efforts.
• Training-provider tuition varies by provider and state; no national price applies. The H Certification Cost breakdown covers how to itemize these charges.

For options and what to look for in a course, see the H Training page.

TSA Screening Timing and the October 2026 Fee Notice

The TSA security threat assessment is separate from the state exam, and it carries its own fee and its own timeline. This is also where current fee information is genuinely unsettled, so read the details carefully rather than trusting a single number.

Here is what the reviewed TSA-related sources show:

The practical timing lesson is simple. Because a fee change takes effect on a specific date, enrolling before or after that date could mean paying a different amount. Check the live TSA enrollment pages, and if you hold a valid TWIC, ask your state whether the comparability provision applies in your situation. Keep in mind that the screening charge is entirely separate from your state's written-exam and endorsement fees.

What to Confirm With Your State Before Booking

Several details that candidates assume are nationwide are actually set by the administering state. Do not infer national rules for any of these. Confirm each one directly:

• Appointment method: whether you must book ahead, can walk in, or must use an approved third-party tester.
• Question count and timer: no exact nationwide question count, scored/unscored split or exam timer was verified. Your state's current manual and testing rules control.
• Test language and delivery: language options and whether the test is written, verbal or automated.
• Retake rules: waiting periods, retake fees and attempt limits.
• Open-book, calculator or at-home testing: no nationwide permission exists for any of these, so check before test day.
• Fees: state exam and endorsement fees vary; no national exam price applies.

The exam itself is multiple-choice knowledge testing built from FMCSA-approved test-generation rules and state question pools, with no separate H skills test. The passing standard under 49 CFR 383.135 is at least 80% correct. For a deeper look at how that threshold plays out, read H Passing Score, and for realistic expectations on difficulty see How Hard Is the H Exam?. Note that no national observed pass rate has been publicly disclosed in the reviewed official sources, as discussed in H Pass Rate: What the Data Shows.

Scheduling Your Prep Around the Five Domains

Once your ELDT and TSA steps are in motion, use the waiting time to study the five federal knowledge areas. No public percentage weights were verified for these areas, so do not assume one is heavier than another. Instead, sequence them by dependency: the regulations come first because every later topic references them.

This four-week layout is an example; your own timeline may stretch or compress depending on how quickly your provider and TSA process things. For a full breakdown of each area, see H Exam Domains: Complete Guide to All 5 Content Areas, and for a structured approach to retention, the H Study Guide walks through first-attempt preparation. When you are ready to test yourself, the H practice test lets you drill these areas under exam-style conditions, and the H Cheat Sheet condenses the must-know facts for last-minute review.

Renewal Deadlines: The Dates That Come Back Around

Your first test date is not the last date you need to track. Two federal provisions create recurring deadlines:

• Five-year ceiling: Under 49 CFR 383.141, states must renew H endorsements every five years or less, with the applicable security requirements. Your state may use a shorter cycle.
• Knowledge test at CDL renewal: Under 49 CFR 383.71(d)(3), retaining H when you renew your CDL requires passing the hazardous materials knowledge test again.

That second point catches many drivers off guard. The H endorsement does not simply carry forward; you generally need to be ready to test again when your CDL renews. TSA screening requirements also recur on the endorsement's renewal cycle, and the TWIC comparability provision can align expiry dates when it applies. No H-specific continuing-education total is published in these provisions.

Put your renewal window on your calendar the day you receive the endorsement, and start refreshing your knowledge well before your CDL renewal date. If the endorsement is part of a longer career plan, the H Jobs overview and the Is the H Certification Worth It? analysis help you weigh ongoing renewal effort against the opportunities it opens.

Test-Day Preparation

A well-timed exam can still go wrong on logistics. Before your appointment, verify the following with your state:

• The exact identity, citizenship or immigration documents the office requires
• Proof that your ELDT completion has been reported
• Your TSA enrollment status or TWIC documentation, if applicable
• Payment methods accepted for state exam and endorsement fees
• Whether you must bring anything specific, or are prohibited from bringing reference materials

Arrive early, since walk-in and appointment systems vary by office. Because the pass line is at least 80%, treat every question as worth carefully reading, especially scenario questions that combine shipping papers, placarding and emergency response in a single stem.
