NYSSIS (New York State Student Identifier System) is a NYSED-developed technology that assigns and maintains unique student identifiers based on an LEA-submitted set of student demographic data, fed into a matching algorithm, and returned with either a matched ID, a new ID, or placed in a Hold Queue for manual resolution. IDs are used to provide longitudinal continuity for a student's records over their time in the NYS Student Information Repository System (SIRS).
