Policy makers are caught between two powerful forces in relation to testing in America''s schools. One is increased interest on the part of educators, reinforced by federal requirements, in developing tests that accurately reflect local educational standards and goals. The other is a strong push to gather information about the performance of students and schools relative to national and international standards and norms. The difficulty of achieving these two goals simultaneously is exacerbated by both the long-standing American tradition of local control of education and the growing public sentiment that students already take enough tests.
Finding a solution to this dilemma has been the focus of numerous debates surrounding the Voluntary National Tests proposed by President Clinton in his 1997 State of the Union address. It was also the topic of a congressionally mandated 1998 National Research Council report (Uncommon Measures: Equivalence and Linkage Among Educational Tests), and was touched upon in a U.S. General Accounting Office report (Student Testing: Issues Related to Voluntary National Mathematics and Reading Tests).
More recently, Congress asked the National Research Council to determine the technical feasibility, validity, and reliability of embedding test items from the National Assessment of Educational Progress or other tests in state and district assessments in 4th-grade reading and 8th-grade mathematics for the purpose of developing a valid measure of student achievement within states and districts and in terms of national performance standards or scales. This report is the response to that congressional mandate.

The issues surrounding the comparability of various tests used to assess performance in schools received broad public attention during congressional debate over the Voluntary National Tests proposed by President Clinton in his 1997 State of the Union Address. Proponents of Voluntary National Tests argue that there is no widely understood, challenging benchmark of individual student performance in 4th-grade reading and 8th-grade mathematics, thus the need for a new test. Opponents argue that a statistical linkage among tests already used by states and districts might provide the sort of comparability called for by the president''s proposal.
Public Law 105-78 requested that the National Research Council study whether an equivalency scale could be developed that would allow test scores from existing commercial tests and state assessments to be compared with each other and with the National Assessment of Education Progress.
In this book, the committee reviewed research literature on the statistical and technical aspects of creating valid links between tests and how the content, use, and purposes of education testing in the United States influences the quality and meaning of those links. The book summarizes relevant prior linkage studies and presents a picture of the diversity of state testing programs. It also looks at the unique characteristics of the National Assessment of Educational Progress.
Uncommon Measures provides an answer to the question posed by Congress in Public Law 105-78, suggests criteria for evaluating the quality of linkages, and calls for further research to determine the level of precision needed to make inferences about linked tests. In arriving at its conclusions, the committee acknowledged that ultimately policymakers and educators must take responsibility for determining the degree of imprecision they are willing to tolerate in testing and linking. This book provides science-based information with which to make those decisions.

This book describes a cost/performance trade-off model useful for illustrating the effects of budget decisions on the quality of expected performance in the military enlisted force. The model links recruit quality to job performance on the one hand and personnel costs on the other. Understanding these linkages provides a clear rationale, based on performance and cost differences, for choosing applicants for military service.
The book examines trends in the quality of military personnel from the beginning of the All-Volunteer Force in 1974 to the year 2000 and beyond. It discusses technical issues associated with the development of the various components of both cost and performance linkages and presents applications of the fully developed model.

This celebrated primer presents an introduction to all of the key ingredients in understanding computerized adaptive testing technology, test development, statistics, and mental test theory. Based on years of research, this accessible book educates the novice and serves as a compendium of state-of-the-art information for professionals interested in computerized testing in the areas of education, psychology, and other related social sciences. A hypothetical test taken as a prelude to employment is used as a common example throughout to highlight this book''s most important features and problems.Changes in the new edition include: *a completely rewritten chapter 2 on the system considerations needed for modern computerized adaptive testing; *a revised chapter 4 to include the latest in methodology surrounding online calibration and in the modeling of testlets; and *a new chapter 10 with helpful information on how test items are really selected, usage patterns, how usage patterns influence the number of new items required, and tools for managing item pools.
