We examined the classification accuracy of Curriculum-Based Measurement in writing (CBM-W) Picture Word prompts scored for words written (WW), words spelled correctly (WSC), and correct word sequences (CWS). First graders (n = 133) were administered CBM-W prompts and the Test of Written Language-Third Edition (TOWL-3; Hammill & Larsen, 1996).…

Purpose: Researchers have developed a constellation model of decodingrelated reading disabilities (RD) to improve the RD risk determination. The model's hallmark is its inclusion of various RD indicators to determine RD risk. Classification methods such as logistic regression (LR) might be one way to determine RD risk within the constellation…

This study compared reading rate to reading fluency (as measured by a rating scale). After listening to first graders read short passages, we assigned an overall fluency rating (low, average, or high) to each reading. We then used predictive discriminant analyses to determine which of five measures--accuracy, rate (objective); accuracy, phrasing,…

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…

Background and Objective: Research has repeatedly found that students who have not developed sufficient reading skills by the third grade have lower rates of high school graduation and post high school outcomes. A growing body of literature has examined how the use of curriculum-based measurements (CBMs) can be used to identify these struggling…

The purpose of this report was to explicate the use of logistic regression and classification and regression tree (CART) analysis in the development of early warning systems. It was motivated by state education leaders' interest in maintaining high classification accuracy while simultaneously improving practitioner understanding of the rules by…

With the pressure in education to develop a 21st century learner with higher-level thinking skills, many educators connected previous state curriculum to the Common Core State Standards (CCSS). Missouri's Department of Education experts paired the previous state's curriculum known as the Missouri Grade Level Expectations (MO GLEs) with a…
