UM, our experience suggests that it often equals some chimera of the three things-- local/state/district policy + local virtual school administrative/board policy + national corporate policy.
The mix is a bit unpredictable, however. The only thing that is certain is that any HARD limits that are in written law/policy can't be easily circumvented. Beyond that it's policy and caprice, I'm afraid.
You don't really know until you ask. Our experience was that it was slightly more flexible than the local standard, which was WAY more flexible than the state as a whole, and moderately flexible at the corporate level (and that has changed somewhat since 2006) and that our local administration has been VERY willing to go to bat for us with corporate players who were obstructionist.
