Federal law defines eligibility for English learner (EL) classification differently for Indigenous students compared with non-Indigenous students. To be EL-eligible, non-Indigenous students are required to have a non-English primary language. Indigenous students, by contrast, can be English-dominant or English monolingual. A critical question,…

Currently 15 percent of U.S. students receive special education services, a widespread intensive intervention with variable effects on students. Spurred by changes in federal policy, many states and districts have begun adopting the Response to Intervention (RTI) approach to identifying students to receive special education services. RTI seeks to…

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…

Children with attention-deficit/hyperactivity disorder (ADHD) may also have undiagnosed developmental coordination disorder (DCD). Prevalence rates of the ADHD/DCD comorbidity are estimated between 30% and 50%. Given the significant impact these disorders have on a child's occupational performance, lack of detection of DCD is of concern.…

Prior research has documented substantial inequity across, racial, ethnic, and socioeconomic lines within the population of students identified as gifted. Less attention has paid to the equity of gifted identification for student learning English or those with disabilities and what effect state policies toward gifted education might have on these…

Students with specific learning disabilities (SLD) represent roughly five percent of U.S. public school students aged 3-21. Current federal policy outlines guidelines for identification of SLDs, while ultimately leaving specific procedures to the determination of state and local education agencies. Research into how the method used in…

Differential diagnosis of autism spectrum disorder (ASD) among intellectually-able adults often presents a clinical challenge, particularly when individuals present in crisis without diagnostic history. The Personality Assessment Inventory (PAI) is a multiscale personality and psychopathology instrument utilized across clinical settings, but to…

This study used a survey designed to establish the predictors of teachers' competence in identifying pupils with suspected cases of learning disabilities. An instrument developed by the researchers, the "Questionnaire on Teachers' Competence in Identifying Pupils with Learning Disabilities" (QTCIPLD) gather data from a sample of 200…

Purpose: Sentence repetition and nonword repetition assess different aspects of the linguistic system, but both have been proposed as potential tools to identify children with developmental language disorder (DLD). Cross-linguistic investigation of diagnostic tools for DLD contributes to an understanding of the core features of the disorder. This…

Investigated internal consistency reliability and criterion validity of the Asperger Syndrome Diagnostic Scale (ASDS) in a well-characterized sample of 120 children ([X-bar][subscript age] = 9.91; autism [AUT] n = 54; non-autism [NOT] n = 66) who completed comprehensive outpatient evaluations with a gold-standard measure, the Autism Diagnostic…

Since 1978, the Education for All Handicapped Children's Act (now IDEA) committed Congress to provide 40 percent of the average per pupil spending to educate children with disabilities. While states have used a variety of special education funding formulas to attempt to meet the needs of children with disabilities, the funding has never approached…

This study examined the reliability and validity of the 13-item Classroom Observation Scale as used by teachers and non-clinically trained observers to identify children who more likely than their peers to have autism spectrum disorder in less-resourced preschools. A total of 534 children (ages 2;10 to 4;5, Mean = 3;8) from nine Chinese-language…

The implementation of prereferral models was being discussed in educational literature as early as 1979. Over the past decade, schools in the United States have begun to adopt prereferral models to meet multiple goals, such as reducing inappropriate referrals to special education, supporting students who face academic and behavioral challenges,…

Background: Diagnosing and managing attention deficit hyperactivity disorder in adults with intellectual disabilities is currently largely based on findings from assessment and treatment in children or adults without intellectual disabilities. Current evidence suggests that individuals with intellectual disabilities are more likely to have…
