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;…

All but seven U.S. states have laws that govern some aspects of dyslexia screening, intervention, or teacher training in public schools. However, in the three states that mandate child-level reporting, data indicate lower than expected rates of dyslexia identification when compared with commonly accepted dyslexia prevalence rates. To better…

This article examined the association between social position variables (i.e., Hispanic, health insurance coverage, and poverty rates) on the prevalence of specific learning disabilities (SLD) in students between 3 and 21 years of age. We used the 2012 to 2013 U.S. population data from the U.S. Department of Education, Office of Special Education…

Underidentification of students with emotional and behavioral disorders (EBD; emotional disturbance or ED in federal language) is a critical issue, perhaps explainable in part by causal attributions of problem behavior associated with conservatism. Conservatism in 58 counties in the state of California was measured by finding the percentage of…

Disproportionate representation of racially diverse students in special education is a well-documented problem, yet few studies have systematically evaluated disproportionate representation of diverse students with autism. This study examined disproportionate representation of racially diverse students with autism by determining risk and…

Evidence of disparate identification of autism at national and local levels is accumulating, but there is little understanding about disparate identification of autism at the state level. This study examined trends in state-level administrative identification of autism under the Individuals with Disabilities Education Act. Prevalence rates and…

The Centers for Disease Control and Prevention (CDC) estimates that about 1 in 88 children has been identified with an autism spectrum disorder (ASD). CDC's estimate comes from the Autism and Developmental Disabilities Monitoring (ADDM) Network, which monitors the number of 8-year-old children with ASDs living in diverse communities throughout the…

This study examined prevalence and relative risk of school-based autism identification by race, and the relations of each to state characteristics. The sample was drawn from general and special education enrollment data for students ages--21 in 46 states during the 2008-2009 academic year. The results show that 1 in 228 students nationwide was…

This study examined how county-level resources are associated with the identification of children with autism spectrum disorders (ASD) in Medicaid. Medicaid claims from 2004 were combined with county-level data. There were 61,891 children diagnosed with ASD in the Medicaid system in 2004. Counties with lower per-student education expenditures,…

Each year the members of the Interagency Autism Coordinating Committee identify recent research findings that made the most impact on the field. For the 2009 Summary of Advances, the IACC selected and summarized 20 studies that gave significant insight into the prevalence of autism spectrum disorder (ASD), the biology of the disorder, potential…

Recent prevalence rates for autism spectrum disorders (ASDs) are now estimated at about 1 in 110 children in the U.S. Increases in public awareness and research funding in response to the growing numbers of children and adults with this disorder have led to numerous important scientific advances over the last several years. Nevertheless, because…

Objectives: This report presents national estimates of the prevalence of diagnosed attention deficit hyperactivity disorder (ADHD) and learning disability (LD) in U.S. children 6-17 years of age and describes the prevalence of these conditions for children with selected characteristics. The use of educational and health care services and the…

A study of 4,151 school districts found a clear association among ethnicity, gender, and mental retardation. Sociodemographic variables were also strongly associated with the proportion of students identified. A logistical regression model that included sociodemographic predictors was significantly better than models with gender and race alone.…

A study involving 4,141 schools investigated gender and race/ethnicity disproportionality among students identified as having learning disabilities. There was a clear association between ethnicity and gender and the odds of being identified as a student with learning disabilities. School sociodemographic factors also associated with the proportion…

A review of 10 studies on the rates of referral for intervention or assessment of students from three racial groups (Caucasian, African American, and Hispanic), found the mean risk ratios comparing the referral rates between African American and Caucasian students were significantly different from zero.
