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…

Assessment is fundamental to school psychology, but its purpose has shifted from making predictions about children to improving outcomes for children. This commentary on the special issue focuses on screening and progress-monitoring decisions that can be used to solve student problems. We outline several psychometric and practical issues that…

Understanding individual students is a complex process. Bronfenbrenner's (1986) seminal Ecological Systems Theory (EST) provides a framework for understanding students by examining the environments in which the child lives including the home, school, community, culture, and so on. One of the main tenets of EST is that it provides a process for…

Given that most schools already conduct reading screening multiple times per year, often using multiple measures, it makes sense to revisit why all this screening may not be giving schools the desired return on investment that they are after. The purpose of this article is to equip school psychologists with an understanding of four common dyslexia…

This article is the second of a series of articles appearing in "Communiqué" about how school psychologists can adopt and promote the evidence-based practices in math assessment and instruction. The focus of this article is on measuring math skills for screening, diagnostic decisions, and progress monitoring. [For the first article in…

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…

Single-case design (SCD) research focuses on finding powerful effects, but the influence of this methodology on the evidence-based practice (EBP) movement is questionable. Meta-analytic procedures may help facilitate the role of SCD research in the EBP movement, but meta-analyses of SCDs are controversial. The current article provides an…

Recently in a "New York Times" op-ed entitled "Is Special Education Racist?" Morgan and Farkas (2015) confront conventional wisdom that there are too many minority students in special education stating, "The real problem is that Black children are underrepresented in special education classes when compared with White…

Academic skills are frequent concerns in K-12 schools that could benefit from the application of applied behavior analysis (ABA). Brief experimental analysis (BEA) of academic performance is perhaps the most promising approach to apply ABA to student learning. Although research has consistently demonstrated the effectiveness of academic…

School psychologists are often seen as leaders in schools. They lead data teams, problem-solving teams, multidisciplinary evaluation teams, and crisis response teams. They are also perceived as leaders regarding intervention, multitiered systems of support, behavior support, collaboration, consultation, special education, assessment, and…

In January 2008, the school-wide data for Alice Birney Middle School in North Charleston, South Carolina were concerning. According to the Measures of Academic Progress (MAP) Reading data, 40% to 48% of the students fell below the 25th percentile at each grade level. The authors realized that these students were not all undiagnosed special…
