Operational testing programs employing item response theory (IRT) applications benefit from of the property of item parameter invariance whereby item parameter estimates obtained from one sample can be applied to other samples (when the underlying assumptions are satisfied). In theory, this feature allows for applications such as computer-adaptive…

This study examined the cross-lingual equating process adopted by a large scale testing system in which target language (TL) forms are equated to the source language (SL) forms using a set of translated items. The focus was on evaluating the degree of error inherent in the routine cross-lingual equating of the Verbal Reasoning subtest of the…

To understand the achievement gap between Black and White students, test performance on Delaware statewide assessments was studied. The study focused on Black-White test score gaps in reading, mathematics, and writing across grades 3, 5, 8, and 10 by achievement level, item format, and gender within each racial/ethnic group over time. The…

A statewide sustained effort to improve student learning in Missouri by adopting and adapting promising research-based educational practices is described. The concept of an Instructional Management System (IMS) with desired learner outcomes determining both instruction and testing was suggested to local school districts beginning in 1980. In 1985,…

The Bookmark Standard Setting Procedure (Lewis, Mitzel, and Green, 1996) is an item-response-theory-based standard setting method that has been widely implemented by state testing programs. The primary purposes of this study were to: (1) estimate standard errors for cutscores that result from Bookmark standard settings under a generalizability…

The primary objective of this study was to investigate overall patterns of gender differences and similarities of test performance in mathematics. To achieve that objective, observed test scores on the Delaware standards-based assessment were analyzed to examine: (1) gender differences and similarities across grades 3, 5, 8 and 10 over 2 years;…

This paper presents the results of ongoing analyses of the reliability of the System for Teaching and Learning Assessment and Review (STAR) as a comprehensive measure of classroom teaching and learning for making teacher certification decisions. Focus was on the effects of high stakes assessment conditions for certification on the generalizability…

Recent trends in achievement test scores among elementary and secondary school students in Iowa are examined. Form 7 of the Iowa Tests of Basic Skills (ITBS) was used to measure the achievement of students in grades 3 and 7; and Form X-7 of the Iowa Tests of Educational Development (ITED) was used for 11th graders. These grade levels were chosen…
