Two studies using similar methods in two states investigated the long-term predictive utility of two single-skill early numeracy Curriculum Based Measures (CBMs) and the degree to which they can adequately predict high-stakes test scores. Data were drawn from kindergarten and first-grade students. State standardized assessment data from the…

Universal screening measures are an integral component of any tiered system of instructional delivery. Recent studies of screening measures have often excluded examinations of bias in predictive validity. The present study examined a common screening instrument for evidence of bias in predictive validity across the four disaggregation categories…

The purpose of this study was to examine the concurrent criterion-related (or convergent) validity of first grade measures from the "Dynamic Indicators of Basic Early Literacy Skills" (DIBELS; Good & Kaminski, 2002). The DIBELS subtests of Phoneme Segmentation Fluency, Nonsense Word Fluency, Oral Reading Fluency, Retell Fluency, and…

The Dynamic Indicators of Basic Early Literacy Skills (DIBELS) are a series of fluency-based measures designed to assess early literacy skills. These fluency-based measures function as predictors of future reading performance and target critical component skills required to learn to read. This study was conducted to establish the convergent…
