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.

Chronically absent means missing 10 percent or more of the days a student was enrolled, for any reason; it counts students enrolled at least 10 days who attended at least once. Group figures the city suppresses for privacy are left out. District figures include transfer schools.
