In most states the School Bus (S) endorsement requires the Passenger (P) endorsement as a prerequisite. That means two separate exams at the licensing office — 20 questions each, 80% to pass each. Preparing for only one is how drivers end up making a second trip.
The School Bus Endorsement Test
Your state administers the S endorsement knowledge test after your ELDT is on file. Here is what you are walking into:
| Test | Questions | To pass | Prerequisite |
|---|---|---|---|
| School Bus (S) endorsement | 20 | 80% — 16 correct | Passenger (P) in most states |
A few states use 25 questions. Confirm the format with your state licensing agency.
This prep gives you 49 practice questions — roughly two and a half times the length of the real test — so you see every topic more than once before test day.
What's Inside
The area around the bus where children are at greatest risk, and how the cross-view, flat, and convex mirrors cover it. Consistently one of the most-tested areas.
The most dangerous part of the route. Student crossing procedure, hand signals, counting students, and what to do when a student drops something near the bus.
When to evacuate and when to stay put, the types of evacuation, and how to run one safely with a bus full of students.
School buses stop at every crossing. The stopping distances, the procedure, and why you never shift gears on the tracks.
Handling behavior without taking your attention off the road, plus the special safety considerations unique to student transportation.
Pre- and post-trip inspection items specific to a school bus, school bus security procedures, and route and stop reviews.
Why 49 Questions Beats a 20-Question Practice Test
A practice test the same length as the real exam shows you a score. It does not show you the topics you would have missed on a different draw. At two and a half times the test length, every area gets covered several times, which is what actually surfaces the gaps.
Right or wrong, you find out why immediately. Wrong answers are built from the mistakes drivers actually make, so a miss teaches you something instead of costing you a point.
After each attempt you see where you are weak — danger zones, evacuation, crossings — and you can retake only the questions you missed. Unlimited attempts, any device.
Where This Fits
53 practice questions for the P endorsement test, which most states require before they will issue S. Same format, explanation on every answer.
