Although testing accommodations are commonly provided to students with disabilities within large-scale testing programs, research findings on how well accommodations allow for comparable measurement of student knowledge and skill remain inconclusive. The purpose of this study was to examine the extent to which 1 commonly held belief about testing…

Standardized assessment in school systems has been the center of debate for decades. Although the voices of opponents of standardized tests have dominated the public forum, only a handful of scholars and practitioners have argued in defense of standardized tests. This article provides a critical synthesis of the controversial issues on…

This study contributes to understanding sources of gender differential item functioning (DIF) on mathematics tests. This study focused on identifying sources of DIF and differential bundle functioning for boys and girls on the British Columbia Principles of Mathematics Exam (Grade 12) using a confirmatory SIBTEST approach based on a…

Four item response theory linking methods (2 moment methods and 2 characteristic curve methods) were compared to concurrent (CO) calibration with the focus on the degree of robustness to format effects (FEs) when applying the methods to multidimensional data that reflected the FEs associated with mixed-format tests. Based on the quantification of…

Many of the currently available statistical indexes to detect answer copying lack sufficient power at small [alpha] levels or when the amount of copying is relatively small. Furthermore, there is no one index that is uniformly best. Depending on the type or amount of copying, certain indexes are better than others. The purpose of this article was…

Through a large-scale simulation study, this article compares item parameter estimates obtained by the marginal maximum likelihood estimation (MMLE) and marginal Bayes modal estimation (MBME) procedures in the 3-parameter logistic model. The impact of different prior specifications on the MBME estimates is also investigated using carefully…

In recent years, there has been a large increase in the number of university applicants requesting special accommodations for university entrance exams. The Israeli National Institute for Testing and Evaluation (NITE) administers a Psychometric Entrance Test (comparable to the Scholastic Assessment Test in the United States) to assist universities…

Simulations were conducted to investigate factors that influence the Mantel, generalized Mantel-Haenszel (GMH), and logistic discriminant function analysis (LDFA) methods in assessing differential item functioning (DIF) for polytomous items. The results show that the magnitude of DIF contamination in the matching score, as measured by the average…

Under the adequate yearly progress requirements of the No Child Left Behind (NCLB) Act (2001), states are currently faced with the challenge of demonstrating continuous improvement in student performance in reading and mathematics. Beginning in 2007 to 2008, science will be required as a component of the NCLB Act. This article describes South…

In a coherent educational assessment system, the relation between the cut scores across the grades of a content area should reflect the goals of the educational system moderated by the state of the standards within that system. In this article, we discuss the need for consistent cut scores across the grades of a content area; we present and…

Psychometricians continue to develop and evaluate methods for linking test scores, both horizontally and vertically. This article describes a social moderation process for articulating (i.e., linking) performance standards across grade levels for an operational state assessment program. The researchers used generated data to evaluate the likely…

Two concerns related to setting performance standards on educational assessments are discussed. First, criteria for a standard-setting process from the point of view of a standard-setting sponsor, called here "institutional criteria," are developed using a state department of education as an example. Four institutional criteria are proposed: (a)…

Developmental (vertical) scales are often constructed for subject areas such as reading and mathematics that are taught continuously in elementary schools. In other subjects such as science, and across a wider grade span, such scales are hard to justify. For tracking student progress and school accountability (including the No Child Left Behind…

This article reports on the consistency of the achievement-level classifications (below basic, basic, proficient, and advanced) established in 1999 for the South Carolina Palmetto Achievement Challenge Tests (PACT; Huynh, Meyer, & Barton, 2000) of English language arts and mathematics. It also utilizes the PACT longitudinal data files of student…

The purpose of this study was to address the effectiveness of a Spanish-English dual-language test booklet in 8th-grade mathematics. This study used analyses of test data (n = 402) as well as information gathered through focus groups (n = 68) and cognitive interviews (n = 18) to assess the accuracy and utility of the dual-language format as a…
