This essay provides a two-pronged critical assessment of a subset of the literature on racial disproportionality in special education: that which aims to estimate racial disparities among otherwise similar children. This body of research has shown that Black students are less likely than "comparable" White students to receive special…

This scoping review analyzes empirical research studies focused on Early Intervention (EI) services, covered under Part C of the Individuals with Disabilities Education Act in the United States, for children birth-to-3 years old with significant support needs (SSNs). The purposes were to gauge the landscape of literature in this area, understand…

The International Classification of Functioning, Disability, and Health is a biopsychosocial framework of health-related functioning designed to provide a unifying system for health care, social services, education, and policy sectors. Since its publication in 2001, the International Classification of Functioning has been used to guide clinical…

Purpose: The aim of this study was to investigate the extent to which researchers in the field of developmental language disorder are utilizing validated methods to diagnose their research participants. Method: We examined 90 research articles published from 2015 to 2019 that included English-speaking participants from the United States who were…

Research on racial and linguistic disparities in disability identification must be grounded on the dual nature of disability as an object of protection and a tool of stratification. This dual nature requires a situated research approach to understand the stratifying power of disability--Who is targeted? Where? How? By whom and to what…

Purpose: Although the 5 studies presented within this clinical forum include children who differ widely in locality, language learning profile, and age, all were motivated by a desire to improve the accuracy at which developmental language disorder is identified within linguistically diverse schools. The purpose of this prologue is to introduce…

This chapter examines how studies focused on the same topic--disproportionality in special education--can generate vastly different conclusions about its sources and causes. By analyzing existing disagreements in the field, we explore essential questions about what constitutes high-quality and relevant evidence when seeking to understand how,…

Borrowing from a clinical psychology observational methodology, thin-slice observations were used to assess autism characteristics in toddlers. Thin-slices are short observations taken from a longer behavior stream which are assigned ratings by multiple raters using a 5-point scale. The raters' observations are averaged together to assign a…

Machine learning has immense potential to enhance diagnostic and intervention research in the behavioral sciences, and may be especially useful in investigations involving the highly prevalent and heterogeneous syndrome of autism spectrum disorder. However, use of machine learning in the absence of clinical domain expertise can be tenuous and lead…

In this article, we critically review the work of Morgan et al. (2015) and offer Disability Studies in Education (DSE) as an alternative conceptualization to traditional research within special education. We first unpack many of Morgan et al.'s (2015) assumptions, which are grounded in deficit discourses about children, family structures, economic…

Four studies into characteristics and instructional needs of students with learning disabilities are summarized in this article. These studies are also reviewed in the wider context of mathematics intervention research in special education. These studies generally rely on qualitative methodology, and they are best understood in light of a…

The goal of the current study was to develop and pilot the utility of two simple internal response bias metrics, over-reporting and under-reporting, in terms of additive clinical value within common screening practices for early detection of autism spectrum disorder risk. Participants were caregivers and children under 36 months of age (n = 145)…

There is debate in the current literature regarding the permanence of an Autism Spectrum Disorder (ASD) diagnosis. We undertook a systematic review of the diagnostic stability of ASD to summarise current evidence. A comprehensive search strategy was used to identify studies. Participants were children with ASD. Risk of bias was assessed by…

Widely regarded as the standard reference in the field, this comprehensive handbook presents state-of-the-art knowledge about the nature and classification of learning disabilities (LD), their causes, and how individuals with these difficulties can be identified and helped to succeed. Best practices are described for supporting student performance…

An e-mail survey of special education directors was conducted to ascertain practices related to implementation of Response to Intervention (RTI) processes in North Carolina schools. The data indicate that special education directors have information about RTI as a method of identifying students with disabilities, but there is little consensus on…
