You missed the latest endorsement that is required for school buses. The "S" for student came through about 2 years ago. As I understand it was a federal requirement. I got Grandfathered in since I had 45 years of bus driving at that time and had worked for the same employer for over 1 year. One advantage for the State of Michigan is that we pay extra for each endorsement. I have a $95. driver's license.
