In most states, this was a matter of political compromise. Because there wasn't support across the board for charter schools, the opposition was concerned they would expand rapidly and this was to make sure they don't.

a very reasonable compromise between those who support further development ... to meet our growing energy demands and the citizens of Florida who oppose drilling in the waters off their coastline.

Our support facilities weren't growing at the same pace as our new schools.

We were very impressed with the support of public schools by our Maine delegation.

We saw that other schools had so much support at athletic events.

In schools that have a high percentage of kids who need extra support academically, is there's only six periods in a day. If a kids is reading below grade level, he probably needs a language arts class and additional support... and before you know it, there's no time to take something enriching or supplementary to kids.
