I have thought, for a long time, that a 4-day school week would be a great idea. Now, in Georgia, due to budget shortfalls, school districts are trying the idea. The students go to school for the same number of hours annually and they have longer school days. The great part is the 3-day weekend.
The kids love it. The teachers love it. Test scores have risen and attendance has improved. The parents, however, find it very inconvenient. The superintendent of one district makes a great point. She says that the school district is not in the business of providing child care. It has been a side benefit to providing education for the students and it is no longer in the position to provide such a service 5 days a week. It's a good point.
