Students with significant cognitive disabilities present an assessment dilemma that centers on access and validity in large-scale testing programs. Typically, access is improved by eliminating construct-irrelevant barriers, while validity is improved, in part, through test standardization. In this article, one state's alternate assessment data…

Instructional time use is an intervention without equal. The measure of such has clear and important implications for special education practice and research. Although exhortations to maximize instruction and thereby student engagement exist throughout the literature, few studies discuss how special education teachers use their time, and none…

This article reviews research examining technical features of curriculum-based measurement (CBM) in written expression. Twenty-eight technical reports and published articles are included in this review. Studies examining the development and technical adequacy of measures of written expression are summarized, beginning with research conducted at…

In this article, the authors review the research on curriculum-based measurement (CBM) in reading published since the time of Marston's 1989 review. They focus on the technical adequacy of CBM related to measures, materials, and representation of growth. The authors conclude by discussing issues to be addressed in future research, and they raise…

Early intervention professionals (N=95) rated their own knowledge and skills in 16 areas of competency. The paper analyzes the distinction between knowledge and skills, identification of item clusters, and changes in ratings over time. Findings provide partial support for the usefulness of self-ratings in the context of inservice education. (JDD)

This article reviews use of the term "best practice" in special education and suggests that the term is misleading unless measurable criteria have been systematically applied. A proposed definition focuses on the theoretical basis for a procedure, integrity of the research design and extent of replication, consensus with literature, process and…

Curriculum-based measurement (CBM) is an approach for assessing the growth of students in basic skills that originated uniquely in special education. A substantial research literature has developed to demonstrate that CBM can be used effectively to gather student performance data to support a wide range of educational decisions. Those decisions…
