Homebound was a farse. The instructor we had at first expected to just transfer work back and forth between the school and my son. Apparently the child is suppose to teach himself or the parent is suppose to do it. That might work for elementary students but my son was taking Latin, Chemistry, Social Studies, Algebra III and Advanced English. I was told that the normal amount of time was seven hours a week but the school got authorization from the state to provide 20 hours (but then the person who told me that had lied to me so often, I don't know what to believe). But once the homebound teacher spent an hour or so collecting the work at school, then driving to our house, there really wasn't that much time to teach. And he was a social studies teacher (my area of concentration) and it, along with English, was the subject for which my son needed the least instruction.
We eventually got a Special Education teacher for homebound. The problem with her was that she simply didn't have the acedemics my son needed. But she did know how to talk to him without provoking him. (Or provoking me. I told the first homebound instructor to leave and not come back when I finally had enough of him telling my son he should be in school and he could if he just decided he was going to... He. had. no. clue. And didn't want one.) But the Special Education teacher gave it a real shot, got along with my son and the school gave him the credit for the year.
That reminds me...you might want to try to get a homebound instructor with Special Education certification.
