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…

The authors summarize evidence from a multiyear study with secondary students with reading difficulties on (a) the potential efficacy of primary-level (Tier 1), secondary-level (Tier 2), and tertiary-level (Tier 3) interventions in remediating reading difficulties with middle school students, (b) the likelihood of resolving reading disabilities…

This study was designed to determine whether the scores obtained from the Kindergarten Diagnostic Instrument (KDI) Test given to children prior to their enrollment in kindergarten would allow educators to identify those children who would eventually qualify for a first grade reading intervention program. A total of 346 children were randomly…

Background: The marked degree of heterogeneity in persons with developmental dyslexia has motivated the investigation of possible subtypes. Attempts have proceeded both from theoretical models of reading and the application of unsupervised learning (clustering) methods. Previous cluster analyses of data obtained from persons with reading…

Response to intervention (RTI) must be combined with comprehensive cognitive assessment to identify children with learning disabilities. This article presents the Cognitive Hypothesis Testing (CHT) model for integrating RTI and comprehensive evaluation practices in the identification of children with reading disabilities. The CHT model utilizes a…

This study employs a program evaluation method to collect intervention effectiveness data for a special education program designed to serve mildly handicapped students with reading difficulties. The potential contributions of effectiveness data to decision making are discussed within the context of a classification model. (Author/LMO)

The paper outlines the rationale and development of curriculum-based measurement (CBM) and its empirical support; summarizes two reading models (Chall's stages of reading development and LaBerge and Samuels' model of automaticity); and discusses how CBM, with its use of oral reading rate measures, and the reading models may validate each other.…

Poor performance on tests of reading comprehension could be the result of weak word-recognition skills, inconsistent attention (ADD), or a combination of the two. Identifying the source of the reading disability (RD) reliably has been difficult because inconsistent attention interferes with reading and weak word recognition skill makes attention…

Using a mixed-methodology, longitudinal design, individual differences and contextual factors related to differential response to general education instruction were examined. We tested a response-to-instruction model reflecting the first three phases of a model proposed by Fuchs and Fuchs (1998). We classified first- and second-grade children…
