The desire for a national picture of educational quality remains a continuing but unresolved goal. A question has been raised among high level policymakers regarding the feasibility of using existing data collected by the states to construct education indicators for state-by-state comparisons of student performance at the national level. A feasibility study was contracted to the UCLA Center for the Study of Evaluation (CSE) to explore the methodological and implementation issues of this approach. The results of the feasibility study are described and discussed in this report. Included in the study are analyses of: (1) the general characteristics of current state testing programs and of the content of currently used state tests; (2) alternative approaches to linking test results across states to create a common scale for purposes of comparison; and (3) the availability of auxiliary information about students and schools and its potential use in creating more valid indicators of achievement. These analyses culminated in a number of recommendations about ways to facilitate the use of state data for national comparisons. These recommendations focus on basic preconditions, proposed approaches, pilot study needs, auxiliary information collection and documentation, and strategies for optimizing political, institutional, and economic support.
