Migrant and Seasonal Head Start (MSHS) programs uniquely support the frequent transitions, including the transition to kindergarten, that children in migrant and seasonal families may experience. Lessons learned from how MSHS programs support transitions may have implications for MSHS and other federally funded early care and education (ECE) programs. This brief discusses children and families served by MSHS, details on MSHS centers, and transition practices offered in MSHS centers. Data for this brief come from the 2017 Migrant and Seasonal Head Start Study dataset.
