The short version is that in the first year there were increased disciplinary incidents and decreased student subjective well-being. This was attributed to the disruption of the change. In further years the disciplinary incidents returned to baseline and the student subjective well-being improved to measurably above the previous baseline. Test scores were not significantly affected.
Magic solutions are seldom magic, especially in education. It all looks so easy from the outside. Remember Daviess County KY and its 13-year (1997-2010) intensive experiment to build better brains? I really though that one was going to work.
