The Republican measure would allow schools to extend their days rather than force them to stay open later in the summer to make up time lost to weather-related closings and parent-teacher conferences. Schools that don't meet the hourly quota would still lose state aid.
Rural schools support the proposal as a way of saving money by keeping doors closed and avoiding higher transportation costs.
The Senate passed the bill last week on a voice vote. The Assembly approved it on a voice vote Tuesday. It now goes to Gov. Scott Walker.
