The children of migratory workers are extremely disadvantaged and are more likely than their nonmigratory peers to live in poverty and experience disconnected educational experiences that can hinder their educational progress and success (Berger 2014; Quandt et al. 2016; U.S. Department of Labor 2017; Wiltz 2016). Congress established the Migrant Education Program (MEP) in 1966 through an amendment to the 1965 "Elementary and Secondary Education Act (ESEA)". The goal of the program under "ESEA," as amended by the "Every Student Succeeds Act of 2015 (ESSA)," is to help meet the unique educational needs of migratory children. The "Study of the Implementation of the 'ESEA' Title I, Part C Migrant Education Program" examined how state MEP grantees and local/regional MEP subgrantees implemented the program's four central components--identification and recruitment, records transfer, service delivery, and coordination and collaboration--to help reduce barriers to migratory children's school success. The findings can be used to help describe the program and the children it serves and to inform program planning and support by MEP grantees, subgrantees, and the Department.
