🚌 School Bus (S) — additional Texas 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
- Texas DPS, via Regional Education Service Centers (RESC)
- State credential
- Texas School Bus Driver Certification, administered by DPS through the Regional Education Service Centers (RESC) — required in addition to the CDL S endorsement.
- Initial training
- 20 hours minimum
- Renewal / in-service
- Re-certification through the DPS School Bus Driver Certification & Re-certification course (the enrollment certificate expires no later than 180 days after issuance).
- Other prerequisites
- Be at least 18; hold a valid license of the appropriate class/endorsement; acceptable driving record; a criminal-history review per the Texas Education Code; a physical exam by a licensed physician with pre-employment/pre-duty drug testing; then complete the basic 20-hour course.
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).
