I live in a school district in MN that went to 4 fays school weeks last year. The district actually lost money. Enough parents transferred their kids to a different school districts that it ate through any cost saving realized. Wow, no-one saw that one coming (morons) There were some students whose parents transferred their children into the district because the four day school week was a benefit. But not enough to make up the losses. They also send additional buses out at noon to pickup/drop off kindergarteners who now have half day kindergarten instead of full day. So they are actually using the buses more now than they used to.
The teachers love the new schedule. Only one hour a day was added to school days, but they got their Fridays off. And they get this for 5 years due to the contracts signed with the teachers union. When they announced the change, my initial thought was why do they only need to add four hours. Out of a 8 hour day you are only educating my kids for four hours?
the problem with my local district is that the admin to teach ratio is way too high and the admins get paid about 15% above state average and the teachers about 5% below. Once the first local levy was voted down after building a new school (levy to build a new school passed in 2005, the next year they asked to pass a levy because they didn't have the funds to operate it. WTF) the superintendent and school board just seemed to want to stick it to the parents. Their attitude seemed to be; you stuck it to us, now we are going to stick it to you.
