"... parents do not have a constitutional right to homeschool their children..."

It's an appeals court ruling in California:

A California appeals court ruling clamping down on homeschooling by parents without teaching credentials sent shock waves across the state this week, leaving an estimated 166,000 children as possible truants and their parents at risk of prosecution.

...

The Second District Court of Appeal ruled that California law requires parents to send their children to full-time public or private schools or have them taught by credentialed tutors at home.

Is Wisconsin any more than a step or two behind this right now?

Anyway, the California teacher's union is happy. Parents aren't. Somehow I think the reactions will reverse by the time the whole thing's finished.
