The school makes a huge difference. We tried two, and the difference was like night and day. I learned about the superior option from a friend who was a school principal on her long service leave (year off). She previously did inspection of trouble students, so had her finger on the pulse. She let me know where to look, and it was a great help. So maybe call up the local education office and have an off the record chat with the people who inspect/resolve issues with home school children's learning, those people will know where the best programs are. In our case, out of state.
