I was at RMA 87-89.
As far as I know, the common elements among all of them were smooshing, raps, propheets and workshops. Mindfuckery 101
Punishment terminologies and methodologies changed over time between the schools. For example, a full-time at RMA was a table restriction at CEDU, from what I have gleaned off the boards so far.
In addition, punishments seemed to become more severe in the 90s in the later schools, i.e. NWA, BCA and Ascent wilderness in terms of absurdity and brutality. One poster here actually said that he was beaten and restrained at Ascent, and they never would have done anything like that in my era.
Most of the info on the later schools is available on the net in the form of the affadavits and testimonies relevant to the lawsuits. Kids left out in the cold, buried (I'm assuming that was a newer version of the funeral exercise in the summit), cutting the lawn with scissors. Those are a few of the things I recall off of the spokesman review article.
The only one I hear very little on is King George. I have read the testimony of one poster so far, and the account was FAR from positive.
I also know next to nothing about CEDU middle school, except for the fact that the very idea of sending adolescents through this makes the hairs on the back of my neck stand up. I think a survivor from there posted here a long time ago, but it might have been a request to hear from survivors of that place. I can't remember.
So far, it has been difficult to paint a complete picture of what the story is, because we are all scattered about, from different eras, different sister schools, and not all of us want to come forward and re-live or re-tell what we have been through. I know that it took me a while to warm up to talking about my own history on the boards.
