This report summarizes Year One and Year Two study findings and describes findings from Year Three of the assessment of school readiness with a strategic sample of children entering kindergarten in fall 2004. It is the intent of the Minnesota School Readiness Studies to use results to inform school administrators and teachers; parents; early childhood education and care teachers, providers, and administrators; policymakers; and the public about progress towards the goals of ensuring that children are ready for school and schools are ready for children. It is expected that the results will promote children's learning and development over time by improving early childhood programs and services, better preparing schools to meet the needs of children as they enter school, and easing the transition for children and families from home to school. The information gathered to complete the studies' developmental checklists is a valuable resource to teachers in modifying curriculum, working with individual children in their classrooms, preparing for parent conferences, and identifying children eligible for Title I and other services. The Minnesota Work Sampling System (WSS)[R]Kindergarten Entry Developmental Checklist and Parent Survey are appended. (Contains 12 tables and 5 charts.)
