WEST PALM BEACH, Fla. (AP) - School district officials are trying to figure out why a kindergartner was left on a school bus for about two hours.

The Benoist Farms Elementary student was taken to St. Mary's Medical Center for observation Monday after officials found him in the bus at the Palm Beach County school district compound.

Officials say the bus drivers are supposed to check the buses before they leave the compound.

School district spokesman Nat Harrington did not identify the bus driver. He did not say whether the driver would face discipline.
