Single-case design has a long history of use for assessing intervention effectiveness for children with disabilities. Although these designs have been widely employed for more than 50 years, recent years have been especially dynamic in terms of growth in the use of single-case design and application of standards designed to improve the validity…

The purpose of this article was to evaluate the quality of research studies and the evidence base for algebra instruction for secondary students with learning disabilities (LD) from 2000 to 2020. We evaluated the quality of methodological rigor of a total of eight single subject and three group design research studies using the 2014 Council for…

There has been an increased focus on the tenets of implementation science in special education research, namely on the degree to which interventions are implemented as intended (i.e., fidelity of implementation) and factors that influence fidelity of implementation. For complex interventions, such as the "Self-Determined Learning Model of…

Scientific evidence should guide the selection of practice for individuals with disabilities. Scientific evidence, however, must be trustworthy to move special education toward greater empirical certainty and more effective policies and practices. Transparency, openness, and reproducibility increase the trustworthiness of evidence. We propose that…

Data from multiple school sources, including informant ratings, systematic direct observations (SDOs), and school wide data (e.g., office disciplinary referrals [ODRs]) are routinely used to guide decision making in the delivery of evidence based practices for students with externalizing and internalizing behavior problems. Over 50 years of…

There has been an increased focus on the tenets of implementation science in special education research, namely on the degree to which interventions are implemented as intended (i.e., fidelity of implementation) and factors that influence fidelity of implementation. For complex interventions, such as the "Self-Determined Learning Model of…

Increasing efforts have been made in the field of special education to identify positive, evidence-based practices (EBPs) to meet the needs of students who engage in problem behavior, with a major goal being to eliminate or limit the use of reactive measures such as restraint and seclusion (Snell & Walker, 2014). Various stakeholders,…

Special education programs vary in the quality of services provided across states, cities, and school districts. There are three major components necessary for a quality special education program for children with complex learning needs. These components include systems level analysis, capacity building for staff, and strong individual student…

Children with ADHD comprise one of the most common groups requiring supports from school mental health providers, yet current school structures and special education policies are not optimally situated to support and adapt to the inconsistent behaviors that are the hallmark of children with ADHD. The present paper reviews and synthesizes…

This article explains a process for improving specific learning disabilities (SLD) eligibility guidelines in a special education cooperative in Nebraska. The Central Nebraska Support Services Program (CNSSP) is a special education cooperative that serves four public school districts and seven parochial schools in central Nebraska. Children birth…

In this article, we discuss conflict between law and science relative to the presumption in special education law that multidisciplinary teams and others identify the causes of problems giving rise to special education needs. First, we explain eligibility criteria, highlighting ambiguities therein and why criteria constitute a mandate for causal…

As the call for evidence-based programs and practices heightens (e.g., the Every Student Succeeds Act), there is little doubt about the urgency to bring solid research into the classroom. Implementing findings generated from rigorous research continues to be a viable, trustworthy, and necessary factor in preventing and addressing learning…

The number of students identified under the Individuals With Disabilities Education Act (IDEA) with an emotional disturbance (ED) has remained remarkably stable over the last 30 years. During this time, approximately 1% of the school-aged population has been identified as disabled under the criteria set forth in IDEA (Kim, Forness, & Walker,…

According to the Centers for Disease Control and Prevention (CDC), the numbers of children identified with Autism Spectrum Disorder (ASD) continues to rise. In North Dakota, the percentage of students identified with an ASD has increased from 1.9% of the total population of students with disabilities in 2004 to 6.2% of that same group in 2013-14.…
