Class B vs. Class A ELDT Requirements: What Changes for Your Curriculum

If you run a Class A program and you're adding Class B — or the other way around — the first question is what actually changes under federal ELDT rules. The short answer: less than you'd fear on compliance, more than you'd guess on curriculum content.

This guide walks the differences appendix by appendix, covers the endorsement layer, and ends with a practical adaptation checklist.

Both classes sit squarely inside ELDT

There is no "ELDT-lite" for Class B. Under FMCSA's ELDT framework, entry-level driver training is mandatory for anyone who wants to:

• Obtain a Class A CDL for the first time
• Obtain a Class B CDL for the first time
• Upgrade an existing Class B to a Class A
• Obtain a school bus (S), passenger (P), or hazmat (H) endorsement for the first time

The rule is not retroactive: per the TPR applicability page, it applies to individuals who obtain a commercial learner's permit on or after February 7, 2022. A driver who held a CDL or endorsement before that date is grandfathered for what they already hold — but still needs ELDT for a class upgrade or a first-time endorsement. That grandfathering nuance matters at enrollment: an experienced pre-2022 Class B driver walking in for a Class A upgrade is an ELDT student, full stop.

For your school, that means every Class B student flows through the same machinery as your Class A students: registered-provider training, curriculum coverage, proficiency standards, and certification submission to the Training Provider Registry before they can test.

Appendix A vs. Appendix B: the curriculum split

The ELDT curricula live in the appendices to 49 CFR Part 380. Per the TPR provider requirements, your instruction "must cover all topics outlined in 49 CFR part 380 appendices A through E, as applicable":

• Appendix A — Class A CDL curriculum
• Appendix B — Class B CDL curriculum
• Appendix C — Passenger (P) endorsement
• Appendix D — School bus (S) endorsement
• Appendix E — Hazmat (H) endorsement

Appendices A and B are structural siblings: both require a theory portion and a behind-the-wheel portion, and the BTW portion in both splits into range and public road instruction. The completion standards are identical in kind — theory requires an overall assessment score of at least 80%, and BTW completion is determined by instructor assessment of proficiency in each curriculum element, with no federal minimum hour requirement for either class (per the TPR training FAQ).

So the compliance shape of a Class B program is a copy of your Class A program. What changes is the content inside that shape.

What actually differs in the vehicle and skills content

The substantive differences follow from the vehicles. Class A means combination vehicles; Class B means heavy straight trucks and buses. When you adapt an Appendix A curriculum to Appendix B (or build B first and later add A), the work concentrates in a few areas:

• Combination-vehicle content drops out. Coupling and uncoupling, fifth-wheel inspection, trailer backing, off-tracking with an articulated vehicle — the hallmark Class A range skills have no Class B equivalent. This is why a Class B BTW course is typically shorter to deliver on the range.
• Straight-truck dynamics come in. Longer single-unit wheelbase behavior, different mirror setup and reference points, different backing geometry. Students who trained in a tractor-trailer mindset need explicit re-instruction, not assumption.
• Air brakes stay — and stay important. Most Class B training vehicles (buses, dump trucks, refuse trucks) run air brakes, so air-brake theory, inspection, and in-cab checks remain core curriculum. Train on a vehicle with air brakes unless you want your graduates carrying an air-brake restriction that makes them unhirable for most Class B jobs.
• Pre-trip inspection changes shape. No trailer, no coupling components — but bus-specific items (passenger entry, emergency exits) appear the moment you point the program at bus employers via the P/S endorsements.
• Vehicle group must match (§380.711). Your training vehicles must be in the same group and type as the CDL your students will test for. A tractor-trailer does not satisfy a Class B BTW program; you need a straight truck or bus.

The endorsement layer: C, D, and E

Class B programs usually exist to feed bus and specialty employers, which makes endorsements part of the product, not an afterthought:

• Passenger (P) — Appendix C: requires both theory and BTW training.
• School bus (S) — Appendix D: requires both theory and BTW training. (S candidates also need P — plan them as a stack.)
• Hazmat (H) — Appendix E: theory only. No BTW component exists for hazmat under ELDT; it's the one branch of the framework you can legitimately deliver without a vehicle.

Each first-time endorsement is its own ELDT event with its own certification. A student leaving your school as "Class B + P + S" generates multiple curriculum completions — and multiple TPR submissions.

TPR submission: identical rules, more records

Here's the operational relief: nothing about TPR reporting changes between Class A and Class B. Under 49 CFR 380.717, you must electronically submit each driver-trainee's certification to the Registry by midnight of the second business day after the driver completes training — the same rule for every class and every endorsement.

Two structural rules to design around, per the TPR training FAQ:

1. Theory and BTW may come from separate providers — and when they do, each provider submits its own driver-specific certification to FMCSA. If you run theory online through a partner or accept transfer students with completed theory, both entities carry submission duty for their portion.
2. Both BTW portions must come from one provider. Range and public-road instruction cannot be split between providers. If a student starts BTW with you, they finish BTW with you.

The practical consequence of adding Class B is volume and variety, not new rules: a mixed A/B school with endorsements is submitting several certification types on rolling two-day deadlines. That's a workflow problem more than a legal one — but it's the workflow problem auditors check first.

The B-to-A upgrade: your built-in second sale

Don't overlook the reverse direction. Because a Class B-to-Class A upgrade requires ELDT, every Class B graduate you produce is a future Class A enrollment — one who already knows your school, your instructors, and your range. Bus and refuse drivers who later want freight wages have to go through a registered provider for Appendix A training; a school that runs both programs captures that upgrade revenue instead of donating alumni to a competitor. Structure your records so a returning B-holder's file picks up where it left off, and market the upgrade path to graduates at the 12–24 month mark.

Curriculum adaptation checklist

Use this when standing up Class B alongside an existing Class A program:

1. Map Appendix B topic-by-topic against your Appendix A theory curriculum; mark shared, modified, and dropped units. Don't just delete combination content — verify every Appendix B topic is affirmatively covered.
2. Rebuild the range syllabus for straight-truck maneuvers; remove coupling/uncoupling and trailer backing.
3. Confirm a compliant training vehicle — correct group and type (§380.711), air brakes if your target employers require them.
4. Verify instructor qualifications for the new class under §380.713/§380.605 and your state's instructor rules.
5. Write Class B proficiency rubrics — element-by-element BTW assessment sheets and an 80%-threshold theory assessment; don't reuse Class A rubrics with a find-and-replace.
6. Add endorsement modules (Appendix C theory+BTW, Appendix D theory+BTW, Appendix E theory-only) if bus or hazmat employers are the target market.
7. Update your TPR listing to reflect the new training types before enrolling students in them.
8. Extend your submission workflow so Class B and endorsement completions hit the Registry within two business days — same deadline, more certification types.
9. Check your state overlay — state hour minimums or licensing conditions may differ by license class.
10. Build the B-to-A upgrade pathway into your catalog and alumni outreach from day one.

The pattern across all of it: same federal skeleton, different muscle. If your Class A compliance is genuinely solid, Class B is an expansion, not a second startup.

Running two license classes plus endorsements on rolling TPR deadlines is precisely the multi-program tracking problem DriverTrack's Class B module exists to solve.
