There's been a lot of excitement about homeschooling in California this year.  I gather the ruckus (I love that word) over legality has pretty much disappeared.  Good.

California has a great California Virtual Academy.   You might have to accept that not all online virtual academies are great.

 There are different types of online distance learning programs.

There are learning services like Time4Learning and Switched on Schoolhouse.
There are private schools paid for by students like Keystone, BJU, and the (one in Baltimore).
There are the virtual schools that are public schools such as Florida Virtual school which provides education for kids of a variety of sorts, but including Florida home school students who are homeschooling in Florida.
