Based on interviews with state personnel and a review of state documents, this report summarizes activities by the states in assessment of educational outcomes for students with disabilities. The report is divided into six sections addressing: (1) state contexts; (2) special education federally reported data; (3) state assessment of outcomes; (4) assessment of achievement; (5) state needs; and (6) practices, programs, and plans related to outcomes. Among major findings are: historically, data collection has documented the educational process, not its results; participation and exit data comprise much of states' data collection efforts; few state-level data collection efforts yield outcomes data on students with disabilities; the extent of participation of students with mild disabilities in state-level general education assessments is uncertain; few states in which students with disabilities do participate in educational assessments report this data; there is inconsistent application of criteria for assessment participation and accommodations for students with disabilities; states are attempting to shift to collecting information on schooling outcomes; states are looking for guidance related to this new emphasis; and some states are exploring use of Individualized Education Program data as a source of outcome data for students with disabilities. Extensive charts and graphs provide supporting details. (DB)
