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…

The 2004 Individuals with Disabilities Education Improvement Act (IDEA) and subsequent regulations published in 2006 have significantly changed the identification process for students suspected of having specific learning disabilities. Rather than using a discrepancy model contrasting intellectual and achievement test results, assessment…

Chromosomal microarray analysis (CMA) has emerged as a powerful new tool to identify genomic abnormalities associated with a wide range of developmental disabilities including congenital malformations, cognitive impairment, and behavioral abnormalities. CMA includes array comparative genomic hybridization (CGH) and single nucleotide polymorphism…

The criterion of discrepancy is used to distinguish children with learning disorders from children with intellectual disabilities. The justification of the criterion of discrepancy for the diagnosis of learning disorders relies on the conviction of fundamental differences between children with learning difficulties with versus without discrepancy…

This report examines trends in the number of special-education students and personnel at both the national and state levels from 2000-01 to 2009-10. It finds that the overall population of special-education students, after decades of increases, peaked in the 2004-05 school year and has declined since. But within this population, individual…

Since the inception of special education, researchers have identified higher proportions of minority students with disabilities than expected. Yet, relatively few studies have considered the contributions of the school context on a large scale to the identification of students with mental retardation (MR), emotional disturbance (ED), and learning…

The aim was to characterize the panorama of developmental disorders in 208 preschool children with a clinical diagnosis of autism spectrum disorder (ASD), referred to a specialized centre, the Autism Centre for Young Children (ACYC), for intervention. At the centre, a research team examined all children according to structured protocols and…

An audit was carried out to gain an overview of the profound and multiple learning disabilities (PMLD) population in a local health trust to inform current and future service provision. An overview of the issues faced in developing clear defining criteria is presented. Published definitions of PMLD were used to identify clients from data held on…

Reading difficulties and disabilities present serious and potentially lifelong challenges. Children who do not read well are more likely to be retained a grade in school, drop out of high school, become a teen parent, or enter the juvenile justice system. Building on the extant research and seminal studies, including the National Reading Panel and…

Using U.S. Department of Education data, the current study examined changes in the rates of special education eligibility classifications. This was done to determine if classification substitution might be an explanation for increases in the number of students being found eligible for special education using the Autism criteria. Results reveal…

A study involving 18 emergency homeless shelters in Los Angeles screened 169 homeless children (ages 6-12) for behavior disorders, learning disabilities, or mental retardation. Results found almost one half of sheltered homeless children screened positive for at least one disability requiring special education services, with behavior disorders…

To produce a greater degree of consistency and reliability in diagnosis of handicapped children, a system called multidimensional actuarial classification is presented for differential diagnosis of mental retardation, inadequate adaptive behavior, social maladjustment, academic under and overachievement, and learning disabilities. (Author/CL)

This study compared interstate variability of prevalence rates for special education categories from 1984 to 1985 through 2001 to 2002, using the coefficient of variation (CV), which is designed to compare variances when the means of the groups compared are radically different. The category of learning disabilities, presumed by many to be the most…

Understanding the criteria and process for determining a student's eligibility for special education services is critical for any educator in an inclusive school environment. Based on the current reauthorization of IDEA 2004, this timely resource offers teachers and administrators an overview of each eligible disability and clear, specific…

California's policies on eligibility and placement of learning and behavior disordered children are discussed regarding their impact in determining which children are served under categories of mental retardation, learning disabilities, and emotional disturbance, as defined in 94-142. Major differences in growth or decrease in numbers of children…
