the staggering logic of florida accountability

i'm trying to understand this. a charter school in tampa bay, FL, has earned "F"s two years in a row according to the state's accountability system. based on my understanding, here is what happened:

1. community isn't happy with their local schools so they create a charter school.
2. parents send their kids to the charter.
3. charter gets an "F" in FL's "A-plus" accountability scheme for the '02-'03 school year.
4. parents still send their kids there. they're "voting with their feet."
5. charter gets an "F" again. according to the accountability scheme, these parents may not choose to send their kids to the charter anymore.
6. charter revoked; school closes down as per accountability requirements in the charter law.
7. parents can no longer send their kids to this "F" charter, but they can send their kids, with a voucher, to a school that is under no accountability scheme whatsoever.

am i missing something? under No Child Left Behind, no child should be "trapped" in an underperforming school (or, in an even more ghastly metaphor, "shackled to" a failing school). under "A-plus," no child is allowed to attend an underperforming charter school. the remedy is to send these kids to private schools where the state has no idea of how well they're performing.

i can only make sense of this if i conclude that what happened with this hillsborough charter school illustrates that the voucher project is not really about choice. it's not about a parent's right to choose the path of their child's education. it's not about free markets. it's not even about accountability.

it's about privatization. pure and simple.
