Per President Biden’s Executive Order, any passenger traveling via public transportation must wear a mask while onboard the vehicle.  The Center for Disease Control has reinforced that School Buses and School District Transportation Vehicles are considered public transportation; therefore:

All passengers and drivers must wear a mask on School District of Wild Rose Buses and other School District Transportation Vehicles until further notice.  This expectation has  also been reinforced by the Wisconsin Department of Public Instruction (DPI) and the Wisconsin Interscholastic Athletic Association (WIAA).
