This report synthesizes the results of activities of the National Center on Educational Outcomes (NCEO) focused on determining whether secondary data analysis of state and/or national data collection programs could produce policy-relevant reports on the status of children and youth with disabilities. The report describes methodology and findings of the NCEO's five-step approach: (1) identifying a working list of potentially useful and relevant state and national data sets; (2) targeting specific data collection programs that include indicators relevant to NCEO's conceptual model of educational outcomes and indicators; (3) conducting disability-sensitive reviews of the targeted databases; (4) analyzing the databases to determine the extent to which NCEO's conceptual model of outcomes and indicators is represented in state and national data collection programs; and (5) developing and completing a list of prioritized secondary data analyses. The report concludes that the exclusion of significant numbers of students with disabilities from both state and national data collection programs and/or the nonexistent or varying disability-specific variables used to identify these students make it all but impossible to describe the status of students with disabilities. Recommendations are offered for improving the collection and reporting of information in state and national data collection programs. These include: develop broader and more uniform definitions of sample eligibility across state and/or national data collection programs; increase adherence to inclusion guidelines; and include follow-up studies and special analyses of ineligible students as a standard component of data collection programs.
