The purpose of this article is to provide a commentary on the current state of several measurement issues pertaining to curriculum-based measures of reading (R-CBM). We begin by providing an overview of the utility of R-CBM, followed by a presentation of five specific measurements considerations: (a) the reliability of R-CBM oral reading fluency…

This study investigated the psychometrics of the "Diagnostic Evaluation of Language Variation-Screening Test" (DELV-S) test using confirmatory factor analysis, item response theory, and differential item functioning (DIF). Responses from 1,764 students in kindergarten through second grade were used in the study, with results indicating that the…

Letter-name identification has been widely used as part of early screening to identify children who might be at risk for future word reading difficulty. The goal of the present study was to examine whether a reduced set of letters could have similar diagnostic accuracy rather than a full set (i.e., 26 letters) when used as a screen. First, we…

As schools implement response to intervention to identify and serve students with learning difficulties, it is critical for educators to know how to evaluate screening measures. In the present study, "Dynamic Indicators of Basic Early Literacy Skills" Oral Reading Fluency was used to compare the differential decisions that might occur in screening…

The authors claim that assessing spelling in Grades 3-12 has utility. They base their claim on data from 875,040 students in Grades 3-12 in 52,923 classes in 840 Florida schools who took the Reading Comprehension, Maze, and Word Analysis spelling portions of the "Florida Assessments for Instruction in Reading" during the 2009-2010 school year. The…

In a response-to-intervention framework, schools typically employ a direct route approach to screening, in which students identified as at risk by a screening process are directly placed into intervention. Direct route approaches require screening decisions to be highly accurate, but few studies examining the predictive validity of reading…
