Background: The diagnostic validity of autism spectrum disorder (ASD) based on Diagnostic and Statistical Manual of Mental Disorders (DSM) has been challenged in Down syndrome (DS), because of the high prevalence of cognitive impairments in this population. Therefore, we attempted to validate DSM-based diagnoses via an unbiased categorisation of…

Historically, neither a positive nor a supportive relationship existed between the population of students designated English language learners (ELLs) and the field of special education. Children's lack of English proficiency was often misinterpreted as a disability and they were referred for special education, whereas others who actually had a…

For identifying children with four major kinds of verbal learning disabilities viz. reading disability, speech and language comprehension disability, writing disability and mathematics disability, the present task was undertaken to construct and standardize verbal learning disabilities checklist. This checklist was developed by keeping in view the…

Psychometric and utility studies on Social Emotional Assessment Measure (SEAM), an innovative tool for assessing and monitoring social-emotional and behavioral development in infants and toddlers with disabilities, were conducted. The Infant and Toddler SEAM intervals were the study focus, using mixed methods, including item response theory…

This dissertation examines the student academic achievement through various mechanisms, put in place by the public school district, classroom student behavior, and negative external shocks to the students' living environment. I examine the impacts of various treatments on student short and long run academic outcomes such as math and English test…

Current clinical diagnosis of Autism Spectrum Disorders (ASD) occurs between 3 and 4 years of age, but increasing evidence indicates that intervention begun earlier may improve outcomes. Using secondary analysis of the Early Childhood Longitudinal Study-Birth Cohort data set, the current study identifies early predictors prior to the diagnosis of…

Reports such as this typically begin with a statistic designed to highlight a problem. The girls and boys to whom this edition of "The State of the World's Children" is dedicated are not problems. Rather, each is a sister, brother or friend who has a favourite dish, song or game; a daughter or son with dreams and the desire to fulfil…

The present study evaluated the stability of math learning difficulties over a 2-year period and investigated several factors that might influence this stability (categorical vs. continuous change, liberal vs. conservative cut point, broad vs. specific math assessment); the prediction of math performance over time and by performance level was also…

This study surveyed a national sample of school psychologists with respect to the identification of reading disabilities (RD). It covers school psychologists' opinions regarding perceived benefits of the use of cognitive assessment in RD identification, both within and outside of an IQ-achievement discrepancy model. The survey also solicited…

This article describes how actuarial methods can supplant discrepancy models and augment problem solving and Response to Intervention (RTI) efforts by guiding the process of identifying specific learning disabilities (SLD). Actuarial methods use routinized selection and execution of formulas derived from empirically established relationships to…

The legal source of schools' use of response to intervention (RTI) is a matter of federal and state special education laws, although its implementation is largely a matter of general education practice. The only mention of RTI is in the Individuals With Disabilities Education Act (IDEA), and it is limited to identification of students with…

When children who are permanently disabled by traumatic brain injury (TBI) return to school, most are placed in mainstream classrooms and incorrectly presumed capable of resuming their education. Only one to two percent are classified as students with TBI, qualifying them for the services they need for their education. The failure to properly…

In a 3-year longitudinal study, 471 children were classified, based on their performances on arithmetic tests in first and second grade, as having persistent arithmetic disabilities (AD), persistent low achieving (LA), persistent typical achieving, inconsistent arithmetic disabilities (DF1), or inconsistent low achieving in arithmetic. Significant…

English language learners (ELLs) who are in the process of acquiring English as a second language for academic purposes, are often misidentified as having Language Learning Disabilities (LLDs). Policies regarding the assessment of ELLs have undergone many changes through the years, such as the introduction of a Response to Intervention (RTI)…

The Office of Special Education Services (OSES) in the Houston Independent School District (HISD) supports students with disabilities in gaining college, career readiness, and independent living skills through active engagement in grade-level curriculum. The purpose of special education is to minimize the impact of the students' disability, while…
