PROMISE Program (Preventing Recidivism through Opportunities, Mentoring, Interventions, Supports & Education) represents the most comprehensive thinking available to address socially unacceptable or illegal behavior, targeting both short and long term academic success, aligning best practice models and Restorative Justice principles, and developing pro-social and resiliency skills.
Basically PROMISE means ... do not suspend, expel or refer to the police
That is an excellent question.
I believe that everyone involved tried to keep a very low profile on it and the media sure didn't want it widely known.
Last month after the shooting was the first I'd heard of it.
