Researchers intending to identify the unique characteristics of dyscalculia rely upon the problematic and imprecise proxy of low mathematics achievement. Although detailed case studies of adults with dyscalculia have offered insight into its characteristics, we do not yet know if these characteristics are unique to dyscalculia and could be used to…

In 2017-18, the number of learners ages 3-21 who received special education services under the Individuals with Disabilities Education Act (IDEA) was 7.0 million, or 14% of all public-school learners. Of that 7.0 million, 13% were Hispanic learners (NCES, 2019). Among ELLs with disabilities, nearly 50% had specific learning disability, and 21%…

Differences in perceptions of disability between students and administrators can play a role in youth's educational experience. This study used data from a cluster randomized controlled trial (C-RCT) of the Self-Determined Learning Model of Instruction (SDLMI) to first compare student self-report of disability status to matched administrative data…

Traditionally, the New Zealand Ministry of Education opposed the recognition of dyslexia. However, since 2007, the Ministry of Education's position has started to change, evidenced by the development of a working definition. In 2021 the Ministry of Education released Three Steps in Screening for Dyslexia (TSSD), an assessment protocol designed to…

The state of Texas has been cited through the U.S. Department of Education under the Individuals with Disabilities Education Act (IDEA) as failing to identify students under the Child Find component of the law using Response to Intervention/Multi-Tiered System of Support (RtI/MTSS). The purpose of this basic qualitative study was to identify…

There is growing evidence that school starting age impacts children's likelihood of receiving special education services, but less is known about variations in this effect. Using a regression discontinuity design, I found that the youngest students in a kindergarten cohort are 40% more likely (p < 0.001) to be placed in special education than…

The problem of disproportionality in special education is complex and requires an investigation of multiple factors related to racial, ethnic, linguistic, and socioeconomic backgrounds, school context, and family characteristics. Researchers have debated whether language minority (LM) students are under or overrepresented in special education, but…

Purpose: Systematic reviews of bilingual children's reading development are very limited, and none of which solely focus on predictors of reading difficulties among those with developmental language disorder (DLD). The present scoping review fills an important need by analyzing the recent research literature on the reading outcomes of bilingual…

We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades.…

Special Education has made many changes in the educational delivery of services since the passing of the No Child Left Behind Act. Within these changes was a shift from the discrepancy model to the Response to Intervention (RtI) model in student identification for special education services. The purpose of this study was to explore the impact RtI…

The present study performed a systematic comparison of DSM-5 and ICD-11 diagnostic criteria for reading disability. We quantitatively investigated the consequences of using DSM-5 or ICD-11, and of the different ways of implementing each diagnostic criterion on the prevalence of reading disability. We did so in a representative sample of the…

The Roma, known as well as gypsies, constitute the largest transnational, non-territorial nation. Research has indicated that the majority of Roma students cannot meet school requirements. Teachers' attributions on the causes of Roma students' underachievement have focused on factors such as poverty, illiteracy and different values system.…

Although it affects as many as one in five individuals in the United States and 80 percent of all children labeled as learning disabled, dyslexia remains poorly understood in educational circles. It was the science supporting the clinical diagnosis of dyslexia that led Laura, a physician, and others to start a public charter school in Baton Rouge…

Teachers' diagnostic practice on students-difficulties is one of the important steps in designing and managing classroom lessons. The purpose of this study was to explore teachers' perception and practices regarding diagnosing students' learning difficulties. The participants of the study were 28 Indonesian mathematics teachers of Junior High…

Nearly 14% of students in the United States receive special education services in public schools (NCES, 2017). Special education programs serve students with a wide range of developmental differences and vary considerably across schools and districts (National Research Council, 1997). Likelihood of identification for special education services…
