The result of this project will be a comprehensive research design for a Migrant and Seasonal Head Start (MSHS) Survey that: describes the characteristics and experiences of children and families served by the programs, reflects the variations in program service delivery approaches, and identifies strengths and gaps in MSHS services. It will be conducted through a collaborative partnership with MSHS program staff and administrators, children and families of MSHS and the Office of Head Start. This partnership will result in practical applied information that will inform MSHS policy and practice. The primary tasks of this project are selecting the most culturally and linguistically appropriate measures and developing plans for sampling MSHS programs, data collection, and data analyses. All planning activities will include close collaboration with MSHS staff.
