School Bus Endorsement


Who is required to have a school bus endorsement on their license?

Public and private school employees who operate school busses transporting students from home to school, school to home, and school-sponsored events are required to have a school bus endorsement on their license. Any school bus driver who has not obtained the new S endorsement may be charged with a violation of driving a commercial motor vehicle without the required endorsement.

Per the Federal Motor Carrier Safety Administration (FMCSA), mechanics operating an empty school bus are not required to have the S endorsement. They are only required to have the proper class of CDL with passenger vehicle (P) endorsement.

What is school bus endorsement grandfathering?

During a period from May 2005 through September 30, 2006, Missouri drivers meeting specific driving history and driving experience criteria were able to "grandfather" to obtain the new S endorsement. As of September 30, 2006, grandfathering is no longer an option. All new S endorsement applicants are required to complete the applicable written and skills tests to obtain a license with the S endorsement.

Am I required to submit proof of training or retake a written or skills test to renew my license with a school bus endorsement?

Drivers less than 70 years of age are required to submit proof of training or testing upon renewal of a license with an S endorsement.

Drivers age 70 or over are required to submit proof of a school bus skills test to retain the S endorsement on their driver license at time of renewal. The license and skills test fees are waived, but a $2.50 office processing fee will still apply.

State law requires drivers transporting pupils for a public school district to complete training, at least 8 hours in duration, providing special instruction in school bus driving. This training must be completed annually. It is the responsibility of the employer or school district to verify the required training has been completed.

The school district will submit the information on DESE’s website and mail the cards and cover letter to DESE.

I have a CDL with a hazardous materials endorsement. What is required to add the school bus endorsement to my license? 

Adding a new endorsement or upgrading CDL class requires a new license transaction.  Based on Federal regulations defined by the USA PATRIOT Act, any applicant for a new or renewal license with a hazardous materials (HazMat) endorsement must have an approved security threat assessment response from the Transportation Security Administration (TSA) prior to issuance. If you do not have a current security threat assessment on file, you will be required to apply and obtain approval from the TSA prior to issuance of a full-term CDL with a HazMat (H or X) endorsement. This also includes applicants adding a motorcycle endorsement.

How do I notify the Department of Revenue when a driver fails a drug, alcohol, or chemical test failure?

Notification should be made to the Department using the Notice of Failure to Pass A Drug, Alcohol or Chemical Test Regarding Persons Possessing School Bus (Form 4684). As the employer, you must provide the following information regarding the employee:

You must certify that the employee failed to pass either a drug, alcohol, or chemical test. You (the employer or officer of the employer) must sign and date the Form 4684. Results of the failed test must accompany the notification to the Department. If any information is omitted, or if the test results are not submitted with the report, the documentation will be sent back to the employer for correction.

Upon receipt of acceptable notification, the Department of Revenue will suspend the school bus endorsement for one year for failing to pass the drug, alcohol, or chemical test. An individual who is aggrieved by the decision of the Director may appeal this decision in the circuit court of his or her residence. The appeal must be filed pursuant to statute 302.272, RSMo.

An individual's school bus endorsement may be reinstated upon completion of the one-year suspension period and payment of a $20 reinstatement fee to the Department of Revenue.

The completed Form 4684 (from the employer or officer of the employer) and any reinstatement fees should be mailed to the following address:
