The extent to which National Assessment of Educational Progress (NAEP) Executive Summary reports are intelligible to policy makers and educators was studied, and recommendations were offered for improving NAEP reporting practices. Detailed interviews were conducted with 59 policy makers and educators. In general, these two groups had considerable difficulty with the presentation of results in the Executive Summary report they were given. Misunderstandings and mistakes in reading the NAEP report were common. Many of the people interviewed had limited prior exposure to the NAEP, were unfamiliar with its reporting scale, and had a limited knowledge of statistics. These shortcomings contributed substantially to the problems encountered in reading the Executive Summary reports. Several recommendations are offered for report improvement. First, all displays of data should be field tested prior to their use in NAEP reports. A second recommendation is that NAEP reports for policy makers and educators should be simplified considerably. A third recommendation is that NAEP reports tailored to particular audiences may be needed to improve clarity, understandability, and usefulness. Appendixes display key tables and figures from the executive summary of the NAEP 1992 mathematics report card, describe participant characteristics, and present the interview protocol.

Hambleton and Sharon C. Slater University of Massachusetts at Amherst Background The main purpose of the National Assessment of Educational Progress (NAEP) is to provide policy makers, educators, and the public with information about what students in the elementary, middle, and high schools know and can do, and to monitor any changes in student achievement over time. In view of the importance of NAEP data for effective educational policy-making and for informing the public about the status of education in America as well as the trends in educational achievement over time, considerable statistical and psychometric sophistication (the best that is available in the country) is used in test design, data collection, test data analysis, and scaling (see, for example, Beaton & Johnson, 1992; Johnson, 1992; Mislevy, Johnson, & Muraki, 1992). Considerably less attention in the NAEP design has been given to the ways in which data are organized and reported to NAEP audiences which include policy makers, educators, and the public though important progress has been made (Beaton & Allen, 1992). Item response theory (IRT) scaling, the use of anchor points and performance standards in score interpretations, and plausible values methodology for obtaining score distributions have been important in enhancing NAEP score reporting. Still, concerns about NAEP data reporting have become an issue in recent years, and were documented recently by Jaeger (1992), Koretz and Deibert (1993), Linn and Dunbar (1992), and Wainer (1994, 1995a, 1995b). Controversy, also, exists with respect to the proper interpretations of anchor levels and achievement levels (i.e. performance standards) which have become central concepts in NAEP reporting (American College Testing, 1993; Forsyth, 1991; Hambleton & Bourque, 1991; National Academy of Education, 1993; Stufflebeam, Jaeger, & Scriven, 1991).
