This study investigated the application of multidimensional item response theory (IRT) models to validate test structure and dimensionality. Multiple content areas or domains within a single subject often exist in large-scale achievement tests. Such areas or domains may cause multidimensionality or local item dependence, which both violate the…

This study examines the practical implications of using state tests to measure student achievement in impact evaluations that span multiple states and grades. In particular, the study examines the sensitivity of impact findings to (1) the type of assessment used to measured achievement (state tests or an external assessment administered by the…

In practice, vertical scales have been continually used to measure students' achievement progress across several grade levels and have been considered very challenging psychometric procedures. Recently, such practices have been drawing many criticisms. The major criticisms focus on dimensionality and construct equivalence of the latent trait or…

This document describes the breadth of the research that the ETS (Educational Testing Service) Research & Development division is conducting in 2010. This portfolio will be updated in early 2011 to reflect changes to existing projects and new projects that were added after this document was completed. The research described in this portfolio falls…

Securing data on students' academic achievement is typically one of the most important and costly aspects of conducting education experiments. As state assessment programs have become practically universal and more uniform in terms of grades and subjects tested, the relative appeal of using state tests as a source of study outcome measures has…

A Teacher Survey was developed for administration to Illinois teachers whose students take the Illinois Inventory of Educational Progress (IIEP). The IIEP are the achievement tests of the state assessment program. The purposes of the Teacher Survey range from determination of a test's curricular validity to investigations of teachers' abilities to…

Educational assessment and, more broadly, educational research in the United States have entered into an era characterized by a dramatic increase in the prevalence and importance of test score use in accountability systems. This volume covers a selection of contemporary issues about testing science and practice that impact the nation's public…

The statewide teaching performance assessment instruments being used in Georgia, North Carolina, and Florida were examined. Forty-one reliability and validity studies regarding the instruments in use in each state were collected from state departments and universities. Georgia uses the Georgia Teacher Performance Assessment Instrument. North…

Statewide minimum competency testing programs have emphasized basic skills in reading, mathematics, and writing. However, continuing concerns are expressed in national reports about the level of achievement, particularly in mathematics and science, and increased testing has been suggested as a means of encouraging curriculum change and evaluating…

In state assessment programs in which performance has no real immediate consequence for the individual examinee, the issue of examinee motivation arises. Some examinees may respond to questions in ways that do not reflect their real knowledge of the test domain. In this study, a new approach was developed to identify students who have responded to…

Issues in designing valid tests for the National Assessment of Educational Progress (NAEP) are discussed. Test scores are often provided without any information on the nature of the tasks represented. Because test domains are defined by individual item writers, the generalizability between tests and items is suspect. While typical content…

Proposes a process approach to validity that addresses assessment validation in the context of high-stakes assessment. This approach includes a test evaluator or validator who considers the perspectives of five stakeholder groups at four different stages of assessment maturity in relation to six aspects of construct validity. Illustrates each…

The U.S. Department of Education has not yet published an official guidance document for using NAEP achievement level scores to confirm state testing results. A review of the literature, however, identified four principles that inform the valid use of NAEP scores in a confirming analysis. The principles address the appropriate NAEP statistics to…

This resource document represents the integration of both practice and theory related to minimum competency testing (MCT), and is largely based on information collected in a nationwide survey of MCT programs. Chapter 1, To Implement or Not to Implement MCT, by Marcy R. Perkins, presents a definition of MCT and a discussion of the perceived…

This paper examines the validity of measures of teacher effectiveness from the Tennessee Value Added Assessment System (TVAAS). It considers the following claims regarding teacher effects: (1) they capture teachers' unique contributions to student learning adequately; (2) they reflect adequate standards of excellence for comparing teachers; (3)…
