Research studies have shown that a smaller percentage of students with learning disabilities participate in state assessments than do their peers without learning disabilities. Furthermore, there is almost always a performance gap between these groups of students on these assessments. It is important to evaluate whether a performance gap on a…

There has been an increased interest in developing computer-adaptive testing (CAT) and multistage assessments for K-12 accountability assessments. The move to adaptive testing has been met with some resistance by those in the field of special education who express concern about routing of students with divergent profiles (e.g., some students with…

Three multidimensional item response theory (IRT) models for testlet-based tests are described. In the bifactor model (Gibbons & Hedeker, 1992), each item measures a general dimension in addition to a testlet-specific dimension. The testlet model (Bradlow, Wainer, & Wang, 1999) is a bifactor model in which the loadings on the specific dimensions…

This paper presents a socio-cognitive framework for connecting writing pedagogy and writing assessment with modern social and cognitive theories of writing. It focuses on providing a general framework that highlights the connections between writing competency and other literacy skills; identifies key connections between literacy instruction,…

This paper presents a framework that institutions of higher education can use to improve, revise and introduce comprehensive systems for the collection and dissemination of information on student learning outcomes. For faculty and institutional leaders grappling with the many issues and nuances inherent in assessing student learning, the framework…

This paper presents the rationale and research base for a reading competency model designed to guide the development of cognitively based assessment of reading comprehension. The model was developed from a detailed review of the cognitive research on reading and learning and a review of state standards for language arts. A survey of the literature…

Item parameter estimates vary for a variety of reasons, including estimation error, characteristics of the examinee samples, and context effects (e.g., item location effects, section location effects, etc.). Although we expect variation based on theory, there is reason to believe that observed variation in item parameter estimates exceeds what…

The purpose of this report is to help in the evolution of these systems by examining the measures used, including, but not limited to, tests. The author asks: Are these the best measures? Are they used right? Are there other measures that should be employed? It is the model of reform itself that is examined, and the report does not address…
