Andy...hi
junerain gave you some wonderful information and I hope it helped you.
My own experience is a slightly different...our group homes are limited to 4-6 housemates. Different levels are achieved according to the resident taking his responsibilities seriously--carrying his own weight re doing fair share of chores, maintaining personal hygiene, school grades...things along those lines.
The ages are kept within 2-4 years if possible. Youthful offenders are allowed in the group homes if the offense was not of a violent nature.
A staff member is there 24/7 for help and guidance...

It's a wonderful way to learn social skills and become independent while working through your health issues.

My best wishes for this to be successful...and Fun for you.

In Peace
