What moves this number
A personal call home on the first unexplained absence, a recorded reason for every absence, and a weekly attendance team meeting where every student gets an owner and a next step. Chancellor’s Regulation A-210 asks every NYC school for all three. BrainBridge makes them the easiest thing your team does each day.
