The Illinois State Board of Education (ISBE) Student Information System includes a unique child identifier for children in publicly funded early care and education (ECE) programs. For each child in the system, ISBE tracks ECE program participation, whether a child meets criteria for being "at risk" and/or low household income, and family structure (e.g., two-parent vs. singleparent family). School administrators and teachers have access to data for an individual child in their classrooms. In aggregate, the state uses descriptive data to meet reporting requirements and to support longitudinal research on child outcomes.
