This report from the Institute for Children, Poverty, and Homelessness (ICPH) is part of its Student Homelessness in New York City series. In this report, ICPH looks at disruptions that often coincide with the experience of housing stability, such as mid-year transfers and chronic absenteeism, can threaten the educational stability. Consequently, these school instability factors may negatively affect academic performance and ruin a student’s ability to graduate. This report focuses on mid-year transfers and chronic absenteeism and how to support students experiencing homelessness so they can fully experience the same educational opportunities as their housed peers.
