I just read the parent's handbook... it's really insane how they're actually using the parents as part of the "indoctrination" process, asking them to hang up on the student (who has probably looked forward to the phone call for the longest time). A very, very effective method of making the student feel isolated, and, needless to say, an effective programming device.
I'm very familiar with IFB (independent fundamental baptist) beliefs... and actually, this sort of thing doesn't surprise me. Fundamentalists such as the people who started Mountain Park also started dozens of other schools, including the extremely cultic college that I attended for a while (Pensacola Christian College) and some of my elementary schools (all of which used ACE, and most of which regularly used "corporal punishment"). It's very sad that people who were called to grace and love are instead turning to legalism and abuse.
