Twice-exceptionality (2e), broadly defined as the co-occurrence of a gift or talent and a disability, has been a part of the educational lexicon since the 1990s, although its empirical backing is limited. We conducted a comprehensive review of the empirical literature on 2e and created a simulation study of 2e. For the latter, we constructed…

The American Academy of Pediatrics recommends that children be screened for autism at 18 and 24 months. It is unknown whether a positive screen usually represents the first developmental concern or is typically preceded by other developmental and/or medical concerns. This study evaluated the proportions of toddlers (M = 18.69 months) who screened…

We examined the predictive utility of the Behavior Assessment System for Children-2 Behavioral and Emotional Screening System (BASC-2-BESS) and Strengths and Difficulties Questionnaire (SDQ) in identifying students with a mental disorder. Data were collected in a two-stage study over 34 months with kindergarten-12th grade (K-12) students (aged…

Identification rates of children with autism spectrum disorders (ASD) have been increasing since the year 2000, while federal special education funding has remained stagnant. Researchers gathered data from states related to individual state funding systems, per pupil spending and identification rates of students with ASD to determine if state…

The prevalence of autism spectrum disorder in the world has increased over the last decade, but the prevalence, incidence, and characteristics of autism spectrum disorder in China were not well understood. Using administrative data, we aimed to estimate the prevalence and incidence of autism spectrum disorder and describe the co-occurring…

Although changes in the identification of dyslexia have shifted in recent years, the rate of identification of dyslexia for English Learners (ELs) continues to lag behind that of monolinguals. Using a large sample of student data reported in the Public Education Information Management system (PEIMS) across two school years (2013-14 and 2019-20;…

Background: Students with ADHD symptoms in post-secondary settings often go undiagnosed which can contribute to challenges for their overall academic success.

Public health and policy planning for adults with intellectual and developmental disabilities (IDD) is imperiled by the lack of ongoing national surveillance data on prevalence and health status. In 2018, the Administration on Intellectual and Developmental Disabilities appointed a workgroup of representatives from key federal agencies and…

Cerebral visual impairment (CVI) is now the most common cause of visual impairment affecting children in the developed world. Due to the increased survival rates of preterm infants and other early insult brain conditions, such as cerebral palsy, hydrocephalus and periventricular white matter injury, the numbers of children with CVI will also…

State legislation serves as a guide and critical influence on the evaluation and identification of students with dyslexia across the United States. The state of Texas has numerous laws and regulations concerning dyslexia, guided by the Texas Administrative Code, Texas Education Code, Texas Occupations Code, and the Texas Education Agency's…

Purpose: Developmental language disorder (DLD) is a lifelong condition that when impacting educational performance is identified and serviced through U.S. schools as outlined in the Individuals with Disabilities Education Act. A few examples of educational categories that refer to DLD are (a) speech or language impairment (S/LI) and (b) specific…

Over the past decade, there has been a rapidly declining trend in the prevalence of students with learning disabilities in South Korea. In 2019, only 1.5% of students receiving special education support were identified as having learning disabilities. This column reports on three current issues related to learning disabilities to provide a greater…

Screening for autism spectrum disorder is the first step toward early detection and diagnosis, thereby impacting the likelihood of children accessing early intervention and, importantly, improving long-term outcomes. This systematic review aimed to (a) establish a clear baseline of autism spectrum disorder screening tools currently used throughout…

We investigated the variability across states in the prevalence of learning disabilities (LD) as reported by the U. S. Department of Education's Office of Special Education Programs (OSEP). This expanded upon the work of Hallahan and colleagues on interstate prevalence rate variability of special education disability categories by focusing on a…

School counselors have a variety of opportunities to serve as advocates and leaders for students identified as twice exceptional (2E). We explore these opportunities and discuss the academic and social/emotional challenges 2E students face and current operational definitions for this population. We also discuss strategies school counselors can use…
