Schools could shorten their academic years and weeks and lengthen their school day to save money.
That's according to a bill approved 62-47 Wednesday by the state House.
The legislation would only allow schools to reduce their school week to four days on a limited basis.
Schools wouldn't have to hold at least 180 days of class each year under the bill under the bill. But they would be required to have nearly 1,100 hours of class time.
The House vote comes a few days after Gov. Jennifer Granholm vetoed a similar bill.
The governor vetoed a bill that would have allowed school districts to reduce the class week to four days while keeping the same number of class hours.
She said she vetoed it because it was tied to another bill that had not yet reached her desk.
The House didn't have enough support for a bill that would have allowed school districts to reduce their week without limits.
