20 questions, multiple choice. You need 16 right to pass (80%). The test focuses on school bus-specific topics like danger zones and student safety.

Danger zones are the areas around the bus where children are most at risk - especially the 10-foot area in front of the bus and the area immediately behind it. You must know how to monitor these zones.

It depends on the felony and when it occurred. Most states have strict disqualifiers for crimes against children, violent crimes, and drug offenses. Check your state's specific requirements.

The endorsement is valid as long as your CDL is valid, but you may need to renew your background check periodically (every 2-5 years depending on state requirements).
