School psychologists can engage in consultation to address inequities in educational opportunities to support multiply marginalized students. This critical work is codified in the NASP 2020 Practice Model, which outlines professional and organizational principles to facilitate school psychologists' engagement in equitable, effective supports to…

In current multi-tier models, students who are not responsive to universal instruction receive supplementary support. Despite most students having co-occurring academic and behavior challenges, their needs are often addressed through separate academic or behavior interventions. This approach may not only be costly for schools, but it also fails to…

Recent studies have suggested single case design (SCD) intervention research is subject to publication bias, wherein studies are more likely to be published if they possess large or statistically significant effects and use rigorous experimental methods. The nature of SCD and the purposes for which it might be used could suggest that large effects…

The central roles of science in the field of remedial and special education are to (a) identify basic laws of nature and (b) apply those laws in the design of practices that achieve socially valued outcomes. The scientific process is designed to allow demonstration of specific (typically positive) outcomes, and to assist in the attribution of…

School psychologists are uniquely positioned to support the delivery of evidence-based mental health practices (EBMHPs) to address the overwhelming mental health needs of children and youth. Graduate training programs can promote EBMHPs in schools by ensuring school psychologists enter the workplace prepared to deliver and support high-quality,…

In this article, we respond to Wolery's critique of the What Works Clearinghouse (WWC) pilot "Standards," which were developed by the current authors. We do so to provide additional information and clarify some points previously summarized in this journal. We also respond to several concerns raised by Maggin, Briesch, and Chafouleas…

Evidence-based practices within a response-to-intervention framework must be implemented with adequate treatment integrity to promote student outcomes. However, research findings indicate educators struggle to implement interventions and logistical considerations may limit the utility of performance feedback, an evidence-based treatment integrity…

Numerous evidence-based classroom management strategies to prevent and respond to problem behavior have been identified, but research consistently indicates teachers rarely implement them with sufficient implementation fidelity. The purpose of this study was to evaluate the effectiveness of implementation planning, a strategy involving logistical…

The purposes of this paper are to (a) propose an operational standard for defining a "practice," (b) encourage development of professional standards for visual and statistical analysis of single-case research, and (c) propose a standard for using single-case research results to identify practices that are "evidence-based." These topics are not new…

The purpose of this article is to provide some perspectives on Lilienfeld, Ammirati, and David's (2012) paper on distinguishing science from pseudoscience in school psychology. In many respects their work represents an intervention for "grandiose bragging," a problem that has occasionally occurred when various non-evidence-based or discredited…

A majority of evidence-based interventions in schools are delivered through consultation models and are implemented by a mediator, such as a teacher. Research indicates that mediators do not always adequately implement adopted evidence-based interventions, limiting their effectiveness in transforming student outcomes. We propose that to transform…

The American Psychological Association Task Force on Evidence- Based Practice for Children and Adolescents (2008) recommended a systems approach to enhancing care in order to improve outcomes for children and adolescents with mental health needs and redress persistent systemic problems with the structure of services. Recommendations for enhancing…

The evidence-based practice movement has focused on identifying, disseminating, and promoting the adoption of evidence-based interventions. Despite advances in this movement, numerous barriers, such as the lack of treatment integrity assessment methods, remain as challenges in implementation. Accurate teacher self-report could be an efficient…

Improving outcomes for children and adolescents with mental health needs demands a broad meta-systemic orientation to overcome persistent problems in current service systems. Improving outcomes necessitates inclusion of current and emerging evidence about effective practices for the diverse population of youth and their families. Key components of…

In recent years, single-case designs have increasingly been used to establish an empirical basis for evidence-based interventions and techniques in a variety of disciplines, including psychology and education. Although traditional single-case designs have typically not met the criteria for a randomized controlled trial relative to conventional…
