You must score at least 80 percent on the School Bus Endorsement knowledge test to pass, which is the federal minimum set by FMCSA. Missing more than four questions on a 20-question test will result in a failing score. Most states allow retakes after a short waiting period, usually one to three days.

Is there a skills test required for the School Bus Endorsement?

Yes, in addition to the knowledge test, applicants must pass a skills test in a school bus representative of the vehicle they will drive. This includes a vehicle inspection, basic control skills, and an on-road driving test. The skills test must be taken in a bus with the same configuration as the endorsement class sought.

What are the eligibility requirements to obtain an S Endorsement?

Applicants must hold a valid CDL (Class A, B, or C), be at least 21 years old for interstate driving or 18 for intrastate in most states, and pass a DOT medical exam. A clean driving record is required, and applicants must submit to a background check including fingerprinting and a review of driving history from all states held in the past 10 years.

How do I register for the CDL School Bus Endorsement test?

Registration is handled through your state Department of Motor Vehicles or Driver Services agency. You must complete a CDL application, pay the endorsement fee (typically $5 to $25), provide proof of identity and residency, and submit a current DOT medical card. Many states require scheduling an appointment in advance for both the knowledge and skills tests.

How much does the School Bus Endorsement cost?

Total costs typically range from $50 to $200, depending on the state. This includes the endorsement application fee ($5 to $25), knowledge test fee, skills test fee ($25 to $100), and any required background check or fingerprinting fees. Training programs, if needed, can add $500 to $2,000 to the total.

How long is the School Bus Endorsement valid?

The S Endorsement remains valid as long as your CDL is current, which is typically renewed every four to eight years depending on your state. You must also maintain a valid DOT medical certificate and complete any state-required annual refresher training. Some states require periodic background re-screening for school bus drivers.

What are the best study tips for passing the S Endorsement test on the first try?

Study your state's CDL manual, specifically the School Bus section, which covers all tested material. Focus on danger zones, railroad crossing procedures, emergency evacuation, and student management. Take multiple practice tests to identify weak areas, and review the pre-trip inspection checklist for school-bus-specific components like mirrors, stop arms, and crossing gates.
