While I know for sure that we are not "siphoning" anything from anyone...

after all, we'd otherwise be homeschooling--

most of my DD's classmates are NOT from homeschooling backgrounds. Most of them are from public schools in their own districts.

So yeah-- they constitute a loss of $$ for their home district. We're the seeming exception there, in that our enrollment results in a small amount going to our district that used to simply stay as a windfall at the state level.

In that sense, cyber-charters are GOOD for districts if they can enroll previously homeschooled children. But they can be very, very bad for districts which are already struggling (rural ones especially, but also inner city schools that need every "good, rule-following" kid they can GET).

Schrödinger's cat walks into a bar. And doesn't.
