This report reviews the major international and regional large-scale educational assessments, including international surveys, school-based surveys and household-based surveys. The report compares and contrasts the cognitive and contextual data collection instruments and implementation methods used by the different assessments in order to identify…

This article reports on the collaboration of six states to study how simulation-based science assessments can become transformative components of multi-level, balanced state science assessment systems. The project studied the psychometric quality, feasibility, and utility of simulation-based science assessments designed to serve formative purposes…

This paper provides a history of ETS's role in developing assessment instruments and psychometric procedures for measuring change in large-scale national assessments funded by the Longitudinal Studies branch of the National Center for Education Statistics. It documents the innovations developed during more than 30 years of working with…

Differential item functioning (DIF) analysis is a statistical technique used for ensuring the equity and fairness of educational assessments. This study formulates a new DIF analysis method using the information similarity index (ISI). ISI compares item information functions when data fits the Rasch model. Through simulations and an international…

The equating process links scores from different editions of the same test. For testing programs that build nearly parallel forms to the same explicit content and statistical specifications and administer forms under the same conditions, the linkings between the forms are expected to be equatings. Score equity assessment (SEA) provides a useful…

In this technical report, we provide reliability and validity evidence for the easyCBM[R] Reading measures for grade 2 (word and passage reading fluency and multiple choice reading comprehension). Evidence for reliability includes internal consistency and item invariance. Evidence for validity includes concurrent, predictive, and construct…

Psychometricians continue to introduce new approaches to setting cut scores for educational assessments in an attempt to improve on current methods. In this paper we describe the Item-Descriptor (ID) Matching method, a method based on IRT item mapping. In ID Matching, test content area experts match items (i.e., their judgments about the knowledge…

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…

In this series of studies, we investigated the technical adequacy of three curriculum-based measures used as benchmarks and for monitoring progress in three critical reading- related skills: fluency, reading comprehension, and vocabulary. In particular, we examined the following easyCBM measurement across grades 3-7 at fall, winter, and spring…

Many students who are deaf or hard-of-hearing are eligible for a signing accommodation for state and other standardized tests. The signing accommodation, however, presents several challenges for testing programs that attempt to administer tests under standardized conditions. One potential solution for many of these challenges is the use of…

Two approaches, the minimax approach and the Rasch procedure, are described for the simultaneous determination of passing scores for subtests when the passing score for the total test is known. (Author/LMO)

The usefulness of traditional concepts of validity and reliability, developed for large-scale assessments, for the classroom context is explored. Alternate frameworks that situate these constructs in teachers' work in classrooms are presented, and their use in an assessment course for preservice teachers is described. (SLD)

The use of performance assessments in accountability programs is discussed. Performance assessments have the potential to measure important objectives not easily measured by multiple-choice tests. Nevertheless, they are not suitable for every purpose, and their use should not be oversold. Many psychometric issues remain to be resolved. (SLD)

Results are presented from a study of portfolio use for large-scale assessment in the Pittsburgh (Pennsylvania) public schools that are more encouraging for the use of this form of assessment than many other studies have been. Requirements for the psychometric integrity of portfolio assessment are discussed. (SLD)

This technical manual provides all major existing information about the technical characteristics of the Kentucky Instructional Results Information System (KIRIS). The assessment component of the Kentucky Education Reform Act Accountability System was in use between 1991-92 and 1993-94 and was referred to as Cycle One. Two sets of test…
