D?æ?

you sound like someone who really cares about their child. I'm not here to tell you that you're a horrible parent for wanting what's best for your son, but you owe it to him to know exactly everything that's going on where he's at. You should be honest with yourself and ask if making your decision to send him there out of desperation and fear. If the main reason you send him there is because "you didn't know what else to do" or "he could end up dead / insane / in jail" then you should get him out of the program as fast as possible.
If your intent is to keep your child in A program no matter what a few red flags to look out for are:
- Using food as an incentive / punishment
- Using a "cool down" room
- Restricting access to the outside world
- Censoring letters (You may not know this is happening)
- Sparse phone calls, and revoking communication between you and your son should he get 'out of line'
- Revoking rights to go to class
- Keywords like "tough love", "Behavioral Modification", and "breaking them down to build them back up again"
Something to keep in mind though, is that even in totally beneficial rehab centers (I assume you sent him there for drug use) involuntary treatment seldom works for very long. Even if he graduates the program and is a model student it is a VERY likely possibility that he will try them again, and this time much harder substances. (increasing with how abusive the program might be, and how long he's trapped)
Until he has the desire within himself on his own to change, you're probably waiting your money that could be better spent towards a good education later on in life. If you take anything at all from what I'm saying it's this. Children do grow up. It might be a bit rough but families are not supposed to be easy. He has free will and he should be able to use it. Most of these programs try to take it away from them and replaces it with rules on how to think.
So, think about what's best for your son, investigate it more. Hear from BOTH sides, not just what the educational consultant and schools have to say. Talk to him, hear what he wants. Ultimately it's his life in there and if it was you, I think you'd want to have a voice in the matter.
I hope this helps.
