A lot of it has to do with wanting to get out earlier in the Summer. When I first started working for the schools we didn't start until after Labor Day and we were out before Memorial day. Now with all of the trying to keep up with other countries and unfunded mandates from the government it has been required that we add hours and days to our calendar. The other side of it just has to do with the amount of information students are able to retain over the summer and how much they lose. The biggest thing that is keeping us from year round school is the lack of A/C in all areas of our buildings. I have a feeling year round will happen in some form before I retire...
