Who needs to take the School Bus Written Test?

The School Bus Knowledge Test is one of the requirements for any CDL holder who wants to receive the School Bus (S) endorsement.

The CDL School Bus Endorsement also requires you to pass the knowledge test for the Passenger (P) Endorsement.

The School Bus Endorsement will also require you to pass background checks, regular medical examinations, and other additional criteria as mandated by your state and local school districts.

To receive your School Bus (P) Endorsement on your CDL, you’ll also need to pass a skills test in a School Bus Passenger Vehicle.
