What kind of degree would it take to be a manager of a group home?

A friend of mine use to work at a group home and I guess there are a lot of corrupt people in the management. He said it is pretty bad, I am not sure what exactly he means. I have a feeling it is about their money and he did say there was some neglect. This really sickens me. I tried to get him to tell on them and report it but I guess they were horrible to him too and he just wants to be done with them. He thinks that the problem goes pretty high up. I am in school now for nursing. I have just gotten started with my prerequisites. I have been wondering if this is what I really want to do. I am not sure. My uncle is in a group home and it is a nice one, not like what my friend has told me. I have been around autistic people my entire life. This kind of job wouldn't bother me and I would probably like it. So I was just curious, what kind of education do you think I would need to be pretty high up with that group home? Even if I didn't work in the home, it wouldn't matter, I just feel so bad for the people living there. It might even make me switch careers. Any advice?
