This article describes how to use data to align student performance to a phase of learning by using a skill-by-treatment interaction, and how that information can help select an appropriate intensification strategy. It describes the Fuchs et al. (2017) taxonomy of intervention intensity through a skill-by-treatment interaction (STI) for reading in…

The purpose of this paper was to examine current mathematics interventions designed for students in kindergarten through eighth grade to determine how often they incorporated the five strands of mathematical proficiency identified by the National Research Council (2001). The five strands are conceptual understanding, procedural knowledge,…

Inequality in reading outcomes is perhaps the single greatest social justice issue faced by school psychologists, and school psychologists need a better understanding of reading theory and its application to intervention to better combat the important issue. The present study examined the active view of reading (AVR; Duke & Cartwright, 2021),…

The current study examined the effects of using a teleconsultation model called ECHO-MTSS on self-efficacy of implementing aspects of data-based individualization (DBI) with 38 educators. Self-efficacy was measured with a 15-item survey that assessed five different areas of the DBI process (i.e., intervention protocol, progress monitoring,…

Measures of Academic Progress (MAP) Skills is a web-based assessment system published by Northwest Evaluation Association (NWEA). The test publishers purport that MAP Skills provides information about essential K-8 building blocks in Language Usage, Mathematics, Reading Comprehension, and Vocabulary to quickly assess student progress toward…

This study examined the classification accuracy for subskill mastery measures administered in mathematics for students in kindergarten and Grades 1, 3, 5, and 7 at fall (n = 564) and winter (n = 602) screening. In addition, response to classwide math intervention was examined as another layer of screening for students in kindergarten and Grades 1,…

School psychologists can impact student outcomes by consulting with teams around data. The current study investigated the effects of consultation with Professional Learning Communities (PLC) teacher teams. The study included four teacher teams, observing their PLC practices and providing consultation. Each team was observed with a…

Research has demonstrated that regular school attendance is necessary for acceptable academic performance and the development of desirable social skills and behaviors. One in seven students in the United States struggles with chronic absenteeism, and 36 states use accountability metrics that are designed to assess attendance rates as part of…

This innovative guide is now in a revised and expanded second edition with an even stronger applied focus. It helps educators harness the potential of single-case design (SCD) as a critical element of data-based decision making in a multi-tiered system of support (MTSS). The authors present simple and complex SCDs and demonstrate their use to…

A skill-by-treatment interaction (STI) isolates skill deficits and manipulates conditions to match them to student needs. Based on the learning hierarchy, preintervention scores can help predict which intervention will be most successful for an individual student. This study compared the efficacy of a modeling and practice-based decoding…

The amount of information that students can successfully learn and recall at least 1 day later is called an acquisition rate (AR) and is unique to the individual student. The current study extended previous drill rehearsal research with word recognition by (a) using students identified with a learning disability in reading, (b) assessing set sizes…

Bronfenbrenner (1977) defined ecological-systems theory (EST) as the study of the multiple interconnected environmental systems that influence individual development. To understand the child, psychologists must fully examine the environment in which the child lives including the home, school, community, and culture (Bronfenbrenner, 1986). There…

The current study used the learning hierarchy/instructional hierarchy phases of acquisition and fluency to predict intervention effectiveness based on preintervention reading skills. Preintervention reading accuracy (percentage of words read correctly) and rate (number of words read correctly per minute) were assessed for 49 second- and…

Multi-tiered systems of support (MTSS) provide instruction and intervention to all students in schools. However, when many students within a setting demonstrate reading difficulties, there is likely a tier 1 problem which makes it infeasible to implement tier 2 or tier 3 interventions with large numbers of students due to limited resources. The…

This indispensable course text and practitioner resource, now fully revised, has helped tens of thousands of readers implement evidence-based interventions to improve students' academic achievement and behavior in PreK-12. The volume presents best-practice guidelines and step-by-step procedures for 83 interventions that can easily be implemented…
