Describes an analytic method for aiding in the generation of subscores that characterize the deep structure of tests and derives a procedure for estimating scores for those scales that are more statistically stable than subscores composed solely of items contained on that scale. Used data from a Praxis administration (9,278 examinees) to show the…

A trilinear chart for understanding the distribution of achievement levels of students' performance in the National Assessment of Educational Progress (NAEP) is described and its use illustrated with data from the 1992 state NAEP mathematics assessment. Trends for all 44 participating jurisdictions are simultaneously displayed. (SLD)

The National Assessment of Educational Progress (NAEP) is an enormous and enormously ambitious project. It generates data of a richness and complexity beyond any simple survey. The broad utilization of the information it provides can be aided through the use of more evocative data displays. In this report, the uses to which data tables are put is…

The accuracy of procedures that are used to compare the performance of different groups of examinees on test items obviously depends on the correct classification of members in each examinee group. The significance of this dependence is determined by the sensitivity of the statistical procedure and the proportion of examinees who are unidentified.…

This report describes the first of a series of research projects which will attempt to characterize the performance of Hawaii's public school system. The measure of performance was the 1992 National Assessment of Educational Progress (NAEP) mathematics examinations and their linked versions used in the 1991 International Assessment. The NAEP was…

In June 1993 the "Wall Street Journal" carried a table of data prepared by the Heritage Foundation that listed the states in order of the average amount they expend on each public school student. The table also contained each state's rank on the average score on the Scholastic Aptitude Test (SAT) and the rank of each state in the average…

This report is the beginning of a series that will examine the performance of the school children of New Jersey relative to the performance of other children in the United States and worldwide. The measure of performance used was the 1992 National Assessment of Educational Progress (NAEP) mathematics examinations and their linked versions of the…

Inferences that spending money (high average per pupil expenditure) does not improve education are questioned because of obvious differences in cost of living; in-state differences; differences in costs and demographic differences; and comparing average measures with measures from a nonrandom sample (Scholastic Aptitude Test scores).
