🚌 School Bus (S) — additional Missouri requirements
Beyond the federal CDL School Bus knowledge + skills test, this state adds its own school-bus driver credential. (Practice here covers the knowledge test only.)
- Administering agency
- Missouri DESE, with the Department of Revenue (DOR)
- State credential
- Missouri requires a CDL with passenger and school-bus (S) endorsements for buses 26,000 lbs or more, or a Class E license with the (S) endorsement for buses under 26,000 lbs; the S endorsement requires passing a knowledge test and a skills test in a school bus.
- Renewal / in-service
- Each school district must provide at least 8 hours of training annually to every school bus driver; drivers must have a physical examination biennially.
- Other prerequisites
- Pass the school-bus knowledge and skills tests for the (S) endorsement; have a medical examiner's statement on file showing physical qualification to operate a school bus (the physical can be done by anyone licensed in Missouri to perform physical examinations).
Languages, fees and rules change — confirm with the official source linked for each state. 待核 / 'To confirm' = not yet confirmed from an official source (shown honestly, never guessed). The 2025 federal English-Language-Proficiency action is roadside out-of-service enforcement, not a state test-language mandate; states set their own written-test languages (Texas and Florida moved to English-only in 2026).
