While
free online high schools are certainly an option that I would not dismiss out of hand, I think that there are a number of other options available as well.
One possibility is
Laurel Springs School in Ojai, California. It serves a wide variety of students including those with extra needs. There is certainly a cost involved, but it may well be worth it if it helps your daughter be successful.
Because my two daughters are Ethiopian, I well understand the need to address issues outside and inside the curriculum.
I am happy to answer other questions about schools here. Feel free to ask away!
