In Tucson, Arizona there was a JW school called the "New World School". It was run by mostly uncredentialed JW's who really didn't have a clue what they were doing. (Although I do believe that the principal of the school and his wife had bachelor's degrees from the University of Arizona) From what I know it was just a school of JW propaganda. I knew a few kids who did go to that school. My cousin's wife taught there and from what I understand she was a very mean teacher; she had no credentials either.
