The finite population correction (FPC) factor is often used to adjust variance estimators for survey data sampled from a finite population without replacement. As a replicated resampling approach, the jackknife approach is usually implemented without the FPC factor incorporated in its variance estimates. A paradigm is proposed to compare the…

Income inequality has soared in the United States over the past half century. Has educational inequality increased alongside, in lockstep? Despite the topic's importance, surprisingly little scholarship has focused on long-term changes in the size of the achievement gap between students from higher and lower socioeconomic backgrounds. The authors'…

Validity evidence based on test content is of essential importance in educational testing. One source for such evidence is an alignment study, which helps evaluate the congruence between tested objectives and those specified in the curriculum. However, the results of an alignment study do not always sufficiently capture the degree to which a test…

Many articles and reports have reviewed, researched, and commented on international assessments from the perspective of exploring what is relevant for the United States' education systems. Researchers make claims about whether the top-performing systems have transferable practices or policies that could be applied to the United States. However,…

The purpose of this study was to examine science assessment data as generated by the 2005 National Assessment of Educational Progress (NAEP), and through the analysis of four research variables: teaching practices, teacher background characteristics, school conditions, and student characteristics, determine their relationship to science…

This technical report and user's guide is designed to provide researchers with an overview of the design and implementation of the 2009 Program for International Student Assessment (PISA), as well as with information on how to access the PISA 2009 data. This information is meant to supplement that presented in Organization for Economic Cooperation…

In the context of Phase Four of the National Assessment of Educational Progress (NAEP) Science Attribute Study, this report includes a discussion of item attributes, an overview of the item attributes used in the study, some psychometric characteristics of the blocks analyzed, a general description of the rule-space methodology, the results…

This report examines the potential of adaptive testing, two-stage testing in particular, for improving the data quality of the National Assessment of Educational Progress (NAEP). Following a discussion of the rationale for adaptive testing in assessment and a review of previous studies of two-stage testing, this report describes a 1993 Ohio field…

The National Assessment of Educational Progress (NAEP) has measured students' progress toward higher achievement since 1969, assessing students in public and nonpublic schools in various subject areas on a regular basis. The NAEP has also collected background information about students to provide a context for interpreting assessment results and…
