This report describes the process followed by the National Center on Educational Outcomes (NCEO) in developing a comprehensive model of educational outcomes and indicators for all students, including students with disabilities, who are completing school. Stage One involved identifying five alternative models of educational outcomes--an educational model, a sociological model, a political/pragmatic model, a psychological model, and a developmental model--and proposing to develop outcomes and indicators as a function of disability severity and age level of the student. In Stage Two, the terms "outcomes" and "indicators" were defined, a set of assumptions to identify "outcomes indicators" was generated, and the work was reviewed and revised. Stage Three brought about more formal and broad-based review of the proposed model. Stage Four's focus was presentation of a new model which distinguished between "enabling outcomes" and "educational outcomes." In Stage Five, additional review and consensus-building took place, resulting in agreement on and publication of a final list of indicators of school completion outcomes. NCEO's plans for the future are outlined. (JDD)
