This study examined the role of initial skill in moderating intervention effects of a 50 lesson mathematics intervention program, ROOTS, for at risk kindergarten students focused on developing whole number concepts and skills. The study utilized a randomized block design with at-risk students (n = 592) within classrooms (n = 60) randomly assigned…

The assessment of screening accuracy and setting of cut points for a universal screener have traditionally been evaluated using logistic regression analysis. This analytic technique has been frequently used to evaluate the trade-offs in correct classification with misidentification of individuals who are at risk of performing poorly on a later…

Early number skills, comprised of both informal and formal skills, are associated with later mathematics achievement. Thus, the development of foundational early number skills is an important aspect of early mathematics instruction. This study explored relations between early number skills gains and mathematics achievement for students at risk for…

The objective of this retrospective study was to determine if second grade Stanford 10 (SAT10) reading and/or language scale scores were predictive of AIMS reading outcomes in third grade, thereby providing a means to identify third grade students at risk of retention in accordance with Arizona's (MOWR) legislation. Early identification of…

This study of advanced readers in Reading First (RF) classrooms was part of a larger evaluation of one state's RF implementation. The study's purposes were to (a) assess the longitudinal growth of advanced primary readers as compared with their non-advanced-reading peers over a 3-year timeframe and (b) determine the degree to which RF classrooms…

Multitiered systems of reading instruction and intervention, including response to intervention, are widely used in early reading by schools to provide more intense services to students who need them. Research using randomized controlled trials has compared innovative Tier 2 interventions to business-as-usual Tier 2 approaches and established a…

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…

This study examines whether the classification and regression tree (CART) model improves the early identification of students at risk for reading comprehension difficulties compared with the more difficult to interpret logistic regression model. CART is a type of predictive modeling that relies on nonparametric techniques. It presents results in…

This comprehensive evaluation of the Dynamic Indicators of Basic Early Literacy Skills Sixth Edition (DIBELS6) set of measures gives a practical illustration of signal detection methods, the methods used to determine the value of screening and diagnostic systems, and offers an updated set of cut scores (decision thresholds). Data were drawn from a…

This study examines the effect of 30 min of small group explicit instruction on reading outcomes for first-grade Spanish-speaking English learners (ELs) at risk of reading difficulties. Participants were 78 ELs from seven schools who were receiving Spanish only, or Spanish and English, whole group reading instruction in first grade. Students were…

The Florida Center for Reading Research (FCRR) Reading Assessment (FRA) consists of computer-adaptive reading comprehension and oral language screening tasks that provide measures to track growth over time, as well as a Probability of Literacy Success (PLS) linked to grade-level performance (i.e., the 50th percentile) on the reading comprehension…

Title I, Part A and Title II, Part A funds are provided to Houston Independent School District (HISD) through the 2015 reauthorization of the Elementary and Secondary Education Act of 1965 (ESEA), also known as Every Student Succeeds Act (ESSA). Both funds focus on enhancing student achievement: Title I, Part A provides supplemental support for…

This paper presents findings of an efficacy trial examining the effect of a multi-tiered instruction and intervention model on first grade, at risk students' reading outcomes. Schools (n = 16) were randomly assigned to the treatment or control condition. In the fall of Grade 1, students were assigned to an instructional tier on the basis of SAT-10…
