There is some controversy going on here in the Fairfax County. Due to budget a shortfall, they are considering going back to half-day kindergarten again as a way to save $13 million dollars. I am not so good with numbers, but for a school system with an annual budget of $2.2 billion (yes, that's billion with a B), $13 million doesn't seem like a lot. A lot of folks, myself included particularly with a kid expected to enter full day kindergarten in nine months, are encouraging the county to consider other options.
There is an interesting debate. My friends who stay home and whose kids go to preschool a couple of mornings a week, complain that full day kindergarten is too long and it's too hard on the kids. My friends who work think half-day kindergarten is a joke because by the time they get to school, get settled, do an activity and have a snack, it's time to go home -- in many ways a far less academic setting then our kids have been receiving at full-day daycare/preschool. Also, it's a pain in the neck for working parents because you don't find out until August before school starts in the first of September if you will have morning or afternoon kindergarten and you have to make arrangements.
