I know how group homes, especially state run ones operate. They’re horrible.
My brother had Autism. Completely non verbal. He was fine until he was three years old. (my brothers autism was exactly like the boy’s autism in that old movie Son Rise)
By the time my brother was ten years old, my mother couldn’t physically care for him any longer.
She placed him in the state ran facility that housed all ages, but in different buildings.
The Air conditioning wasn’t working one night, so an employee propped open a door.
My brother got through the open door and drowned in a pond that was on the grounds.
Even when my brother was alive and we would visit, you could tell that over half the people there didn’t know how to care for people, or they just didn’t care about the people housed there period.
So, in my experience, state run group homes are usually not good, unless they’ve changed a lot since 1987.
