Frequently Asked Questions
How many questions are on the California CDL School Bus endorsement test?
California DMV does not publish a fixed School Bus-only question count on its official CDL pages or Section 10 handbook page. Treat it as a separate DMV endorsement knowledge test and prepare from California Section 10 plus FMCSA School Bus endorsement requirements.
What score do I need to pass the California School Bus endorsement knowledge test?
Federal CDL rules require at least 80% correct on each CDL knowledge test. California DMV also gives applicants three attempts to pass each required knowledge test on the application.
Do I need the Passenger endorsement before the School Bus endorsement?
Yes. FMCSA requires School Bus endorsement applicants to qualify for the Passenger endorsement by passing the Passenger knowledge and skills tests before meeting the School Bus endorsement requirements.
Is ELDT required for the California CDL School Bus endorsement?
Yes, California DMV states that Entry-Level Driver Training is required for CDL applicants obtaining a School Bus (S) endorsement for the first time. DMV electronically verifies ELDT completion before the required skills test, or before the HazMat knowledge test when HazMat applies.
What does the California school bus certificate cost?
California DMV's licensing fee page lists a $25 original application fee for a School Bus, School Pupil Activity Bus, or Youth Bus Driver Certificate. Renewal, replacement, and update transactions are listed at $12.
What should I study first?
Start with California Commercial Driver Handbook Section 10. Then verify CDL, Passenger endorsement, School Bus endorsement, ELDT, and California certificate requirements on DMV and FMCSA pages before scheduling any required test.
