I hear you Sue. I don’t like to invest a lot in a foreign language program until I see my child is really serious about learning it, so I might begin with Getting Started With French, and then follow up with Duolingo. If my student were diligent enough to work through both of these programs, I would be willing to invest in something more expensive and thorough. I would award credit according to time spent on the language.
I’m a bit leery of expensive programs for foreign language because the truth is, very few students actually learn how to speak the language and most usually forget the majority of what they do learn.
My daughter has dabbled in several foreign languages and I am very glad I didn’t purchase a curriculum for each one she was interested in! When she showed an interest in Japanese, I had her use the free components of an online program. After she worked diligently at this for several months, I purchased the other components of the program as well.
This is how I have handled foreign language so that is why I shared those resources even though neither is worth a full high school credit on its own.
Hope you find the right program for your daughter!
