What you describe is why I kept teaching for 31 years.
Oak, in reference to the article you linked, 2 things. One, they are using the restorative justice concept in some schools around here, and two, I had the occasion to deal with a KIPP school last fall, in my old job. One of my clients, transferred to this new charter school. She had been going to a very good elementary school in a very rough part of Lowell. She didn't live near the school, Lowell has school choice in a limited way. This kid was referred for counseling by this public school and I saw her at school. The kid and her mom were relocated here in a "protective" program by the courts in another state, far away, because of DV perpetrated by the father. That said, the KIPP school was uncooperative in every way, to the point I was meeting with the kid in an open area in the cafeteria! One day, I went in, in January, and I was told I could no longer see her at school. Basically, they didn't want outsiders observing their program. There must have been 10 different therapists coming in, from different agencies and we were all banned. It was so creepy, I left every week with a sick feeling in my stomach.
