This course prepares you for the School Bus (S) endorsement knowledge test. It is for a driver who will carry school children. The S endorsement is added on top of the Passenger (P) endorsement, and needs its own knowledge test and a skills test in a school bus. States add their own school bus laws and background checks.
Alabama gives the test at its own driver licensing office, and sets its own fees and required documents, so confirm those with the state before you go.
This course drills 49 questions. Every one is written from 49 CFR Parts 383, 390, 392, 393 and 396 — the federal rules that apply in every state — and names the section that proves its answer. A state may add rules of its own on top of the federal minimum.

Questions
Common questions
Is there an official test, and how is the mock test scored?
80 percent is the federal pass mark for every CDL knowledge test (49 CFR 383.135). No federal rule sets the question count: 49 CFR 383.133 sends the states to AAMVA's test system, which is not public. The count here is the one used by the states that publish theirs -- Michigan's CDL manual and Ohio Administrative Code 4501:1-1-08 -- so your state may differ. 20 questions, 16 correct to pass.
Where do the questions in this course come from?
Every question is written from 49 CFR Parts 383, 390, 392, 393 and 396, and names the passage or section that proves its answer.
Where do I take the CDL School Bus (S) test in Alabama?
Alabama gives the test at its own driver licensing office, and sets its own fees and required documents, so confirm those with the state before you go.
