If Being Early Helps, Why Not Open Earlier?

Since Elementary school, I have wondered why the begging of school schedule and lunch times were so rushed.  A recent letter from the Walnut Hill Elementary reminded me just how crazy the school mornings are.  Mentioned in the letter, the school doors open at 8:20 am, and are literally locked until that time.  The bell to be in calls is 8:35 am.  That gives children who show up when the doors are unlocked only 15 minutes for breakfast and to get to class.  Also in the letter is a statement that basically says statistics prove that kids who get to class on time or early perform better.  It seems, schedule wise, kids here are set up for failure then.  I expressed this concern to my representative on the School Board.  Why not open the doors at 8:10, at least for the kids dropped off by parents?  If it is so important for our children to be early, perhaps the schedule should be adjusted to help support just that, instead of the exact opposite.  Here is a shining example of something very simple we could do to help our kids succeed.  Teacher and administrators just have to show the same initiative to get to school early too, a problem I noticed last year.  Having the kids early to class does no good if the teachers are not prepared.
