My ideal school year would be to start after Labor Day and end by Memorial Day. It could be done easily by eliminating the Teacher Duty Days and the Early Release Wednesdays. In our district the Teachers negotiated to have classes shortened on Wednesdays so they would have time for Prep, Meetings, etc. However, you can't find a Teacher in the Middle School 5 minutes after they dismiss - all gone. The only Teacher I am aware that will allow them to be in his class room prior to school is the Band Teacher (who is AWESOME). Kiki may know of some others, but they are definetly few and far between.
When I had to pick Lisa up from school each day to take her to the gym last year, I asked if she could stay on campus for that early release hour and study in the library or elsewhere. I was told that was not possible. All kids must be off campus immediately following school unless they had a special group meeting (like Band, Dance, etc). All I wanted was a place for her to do her homework rather than wasting the time walking home, only to have me pick her up and drive right back by the school (Yes, I am bitter!!!

)
