Actually, from visiting/touring it this morning, it doesn't look very bad at all!
There's a grand total of 30 kids, from grade 5 through 12. They all have one teacher in the morning, and another in the afternoon: they alternate, so each class has about 15 kids. It's very quiet in there, everyone is expected to do their work, individually, and nothing else. They can't even walk around without permission, and they can't roam the halls without an adult escort.
The school assigned police officer gathers everyone up on Friday afternoons, for a lecture
We were also assured that all kids there are kept so busy, that they'll do more in the few hours that they're there, than they've been doing in an entire day. Also, most kids there are in the same circumstances: they had a momentary lapse of judgement
So far, we're satisfied that it's exactly what she needs. We'll still be looking at the Catholic school, but at $5'000 /yr, it's not an easy decision, especially when money isn't easy to come by.
I'm glad to hear that you got out of it. I think that the lesson is "don't do it" and "use your head". She got caught up in the social goings-on. Even this morning, I caught her trying to use the phone

It's like an addiction to her.
