I think year 'round school is a great idea (now that I'm out, heh...). But, I think each state should enforce the switch at once (similar to the quarter -> semester conversion in Georgia colleges in 99.) This way, afterschool care (day-cares, kid camps {summer camps,etc}, and the like) can all be setup to coincide with the cutover. Also, employers would be able to draft changes to assist parents with time off and such.
I dunno... Most of the above conversations seem to stem from "think of the kids/teachers/administrators". I just think that THEY (school board system) need to take into account the parents.
