A large body of literature demonstrates that children who experience unstable housing and homelessness are at risk for developmental delays and social–emotional challenges. However, there is also evidence of variability in the functioning of these children. Our primary aims were to identify unique profiles among preschool-aged children who were unstably housed and determine whether family-level and classroom-level factors predicted children’s profiles. Participants, drawn from the national Head Start CARES study, were 314 4-year-old children in one of 107 Head Start centers. Teachers’ reports of children’s behavior and social skills were entered into a latent profile analysis that revealed a four-profile structure with four subgroups of unstably housed children that were distinct in their functioning.
