This in-brief technical report documents the results from two different analytic approaches for examining the reliability of the slope for easyCBM® reading measures in Grades K-8. Results varied by grade, assessment measure, and the analytic approach. Results patterns are discussed.

In response to a request for additional analyses, in particular reporting confidence intervals around the results, we re-analyzed the data from prior studies. This supplementary report presents the results of the additional analyses addressing classification accuracy, reliability, and criterion-related validity evidence. For ease of reference, we…

In the following technical report, we present evidence of the technical adequacy of the easyCBM[R] math measures in grades K-2. In addition to reliability information, we present criterion-related validity evidence, both concurrent and predictive, and construct validity evidence. The results represent data gathered throughout the 2009/2010 school…

As part of a Response to Intervention (RTI) model, curriculum-based measurement (CBM) is an evidence-based assessment system that uses screening and formative assessments to help guide instruction. The two primary purposes of this study are to examine the relations between the easyCBM benchmark measures and a statewide large-scale assessment and…

In this technical report, data are presented on the practical utility, reliability, and validity of the easyCBM[R] mathematics (2009-2010 version) measures for students in grades 3-8 within four districts in two states. Analyses include: minimum acceptable within-year growth; minimum acceptable year-end benchmark performance; internal and…

In this technical report, we document the results of a cross-validation study designed to identify optimal cut-scores for the use of the easyCBM[R] mathematics test in the state of Washington. A large sample, randomly split into two groups of roughly equal size, was used for this study. Students' performance classification on the Washington state…

This technical report presents results from a cross-validation study designed to identify optimal cut scores when using easyCBM[R] reading tests in Oregon. The cross-validation study analyzes data from the 2009-2010 academic year for easyCBM[R] reading measures. A sample of approximately 2,000 students per grade, randomly split into two groups of…

In this technical report, the authors describe the development and piloting of reading comprehension measures as part of a comprehensive progress monitoring literacy assessment system developed in 2006 for use with students in Kindergarten through fifth grade. They begin with a brief overview of the two conceptual frameworks underlying the…

Focus groups were used to examine the needs of students taking a computer adaptive math assessment. The assessment designed using universal design and item response theory. Focus groups included teachers, administrators, child advocacy groups, and 3rd grade students and parents from the following groups: students with disabilities, students in…

This technical report documents the procedures followed in developing student and teacher surveys to gather information about the accommodations students are accustomed to receiving and those that might be beneficial on a mathematics test delivered on the computer. It provides documentation of the technical adequacy of the survey instruments, as…
