Some Mississippi legislators are trying to undo a law that requires the school year to start later in August.
The Senate voted 31-15 Wednesday to do that. The House and the governor would have to agree before anything could change.
The proposal came from Republican Sen. Videt Carmichael of Meridian, who says local districts should decide when the school year begins.
Under a law that takes effect for the first time in the 2014-15 school year, classes can begin no earlier than the third Monday in August.
Most Mississippi districts have been starting earlier.
Gulf Coast tourism officials persuaded lawmakers to set the later start date, saying it would boost the economy by giving families more vacation time.
Carmichael's proposal was an amendment to Senate Bill 2571.
