This booklet is designed to be used in developing a system of indicators of educational outcomes for 3-year-old children, including those with disabilities. The document summarizes a conceptual model of educational outcomes, lists specific outcomes for the early childhood level, and matches indicators with each of the outcomes. It then focuses on identifying information sources for each of the 62 indicators listed in the conceptual model. The model addresses eight outcome domains: presence and participation, family involvement/accommodation and adaptation, physical health, responsibility and independence, contribution and citizenship, academic and functional literacy, personal and social adjustment, and satisfaction. Sample information sources suggested for use in measuring the outcomes include: parent surveys or interviews, local or state poverty rate statistics, surveys of private and community day care programs, local education agency records, and teacher observations. Appendices list instruments for assessing each domain and sources of the instruments. (Contains 12 references.) (JDD)
