There are many, many such programs. One, in particular, that is well thought of is Laurel Springs School . The advantage to this school is it provides as little or as much support as you need (and is priced according to that support). While far from the cheapest program, it is considered quite good. And they have a long list of famous/semi-famous graduates from Hollywood and professional sports. There are, of course, many others. Tom Nixon
Choice 2000 online charter school is another good choice http://www.choice2000.org/ ..as is the Florida Virtual School http://www.flvs.net/
