I did not go to the same schools as MAD or If You Want to Know... I went to CEDU RS. And at my school, especially with the education I now have, there is no way I could say that CEDU was anything other than unethical, abusive, and coersive in its therapeutic and academic capacities. Also, the staff were either power trippin' cultists (some with shady histories who I would NOT want associating with my child)or impressionable newbies who were fucked up themselves and needed a niche to work out their own crap.
Who knows why Devin was sent to this school? During my time, parents often sent their children to CEDU because they were miseducated on the type of place it really was. For example, some parents thought it was a school for non traditional learners. (It wasn't. It was a group home.) Many parents overreacted when their children rebelled and sent them to CEDU. Other parents were fed up with their out of control kids and either didn't want to or didn't know how to handle it themselves. Some kids had serious problems, such as depression, etc. that remained unaddressed by CEDU.
Whatever the case, CEDU's faults were not isolated, but SYSTEMIC.
Having said all that, of course there were also good times to be had. Many people loved the wilderness trips, for example. There were special events that were interesting. I liked all the outdoor stuff: wilderness, the ropes course, the olympics, even working outdoors with my peers...
Other people enjoyed the intense relationships you can't help but form at CEDU given the unique experiences you share together. Sundays were good days because the week is so structured and taxing that it was nice to be in a beautiful locale and do what you want to do. I don't think I ever valued free time as much!
I don't know what Devin's BCA experiences were, but I'm deeply sorry for your loss. Even people who complain about CEDU often say they had forged some great friendships and unique experiences. I will say that because you are pushed so hard, you do experience some of your highest highs at the school.
It sounds like you are trying to make sense of it all. I wish you much luck. Have you written to his family?
