NCEO Technical Reports: Secondary Analysis of State Assessment Data: Why We Can't Say Much About Students with Disabilities (#10)
This year 1994 report summarizes activities of the National Center on Educational Outcomes (NCEO) directed at producing a report on the status of students with disabilities from the secondary analysis of state collected achievement data. Although more than half of the 50 states reported that large-scale achievement data were available for some students with disabilities, potentially usable data were obtained from only six states. The report describes numerous difficulties encountered in attempts to collect and aggregate state achievement data on students with disabilities and concludes that it was not possible to produce a synthesis report on the achievement status of students with disabilities from aggregated state data bases. Recommendations are presented for improving the probability of conducting such analyses in the future.
