While children are ready for school by virtue of having attained the chronological age for school entry established by the state, school readiness refers to the conditions that promote their readiness to succeed in school. Wisconsin is one of 17 states participating in the National School Readiness Indicators Initiative, the aim of which is to build an agenda for improving school readiness and ensuring early school success. Based on the initiative, this report provides a definition of school readiness, a comprehensive set of indicators that operationalize school readiness, the data available in the State, and an overview of data still needed to complete the picture of school readiness in Wisconsin. The indicators comprising the School Readiness Outcomes Framework, and their relevance to early education, are detailed in the areas of: (1) Responsiveness--family and community support for school readiness, including health care and physical development, family resources, early care and education, and community conditions; (2) Receptiveness--school's readiness for children, including teacher training and professional development, school policies and environment, transition practices, and classroom environments; and (3) Ready Children, including health and physical development, social and emotional development, approaches to learning, language development and communication, and cognition and general knowledge. The report concludes with recommendations for the state to adopt a broad definition of school readiness, adopt the School Readiness Outcomes Framework, and commit to the development of a comprehensive, interdepartmental data infrastructure that supports the School Readiness Outcomes Framework. The report concludes with a table of data on the school readiness indicators. A list of members of the Wisconsin School Readiness Indicators Initiative Steering Committee is appended.
