In an effort to cut costs without reducing programs, colleges around the nation are cutting back to four-day class schedules.

Plans for four-day weeks have been announced at colleges in New York, Missouri, Georgia, and other states. The idea is even being considered at a few high schools.

The shift is expected to reduce heating and maintenance costs, and reduce commuting expenses for students, faculty, and staff. 

On colleges with large on-campus student populations, a four-day week could make it easier to schedule student events and meetings. On commuter campuses, it could have the reverse effect.
