Brigham Young University has online high school courses in 10 languages. I'm aware of several high schools around the country that use our content in a "high school suite" model, where their teacher uses our course materials in the way that works best for their school – fully online, blended, or as materials supplements. Before I came to BYU, in fact, I was the administrator of a charter school where we used BYU's online high school materials for our 8-12 grade students. It was a good fit for our needs, because our teachers needed resources for our remote students. So they were able to use the BYU content to create blended and fully online language courses and resources. It might be useful for you.
