Developmental dyscalculia (DD) is a mathematical learning disability that occurs in around 5%-7% of the population. At present, there are only a handful of screening tools to identify children that might be at risk of developing DD. The present study evaluated the classification accuracy of one such tool: The Numeracy Screener, a 2-min test of…

Researchers intending to identify the unique characteristics of dyscalculia rely upon the problematic and imprecise proxy of low mathematics achievement. Although detailed case studies of adults with dyscalculia have offered insight into its characteristics, we do not yet know if these characteristics are unique to dyscalculia and could be used to…

Developmental language disorder (DLD) is a language deficit affecting approximately 7% of the general population and does not associate with any hearing impairment, neurological damage, or mental disorder. In DLD, the complications arise over time due to the learning difficulties experienced, which causes eventual cognitive delay compared to…

Due to lack of consistency among diagnosis practices of students with specific learning disabilities (SLDs) in the state of Texas, as well as other legal matters regarding diagnoses of SLD, there is a divide among eligibility criteria for students around the state. Currently, the three models that have received the most attention of SLD…

Previous studies of K-12 dyslexia legislation have described broad trends in legislative content, such as the presence or absence of screening and intervention requirements. This study uses document analysis to provide a finer-grained description of the laws to highlight critical variation in policy that will directly affect (a) the number and…

This study examined the identification frameworks, specific models, and assessment practices used by school psychologists to identify students with specific learning disabilities (SLD) in public schools in the United States. We surveyed school psychologist practitioners using an online survey, conducted a review of state regulations addressing…

This study investigated the psychometric properties of the Early Numeracy Screener. The Early Numeracy Screener is a teacher-administered, paper-and-pencil test measuring counting skills, numerical relational skills, and basic arithmetic skills. Three hundred and sixty-six first graders took the Early Numeracy Screener at the beginning of the…

The goal of this study was to investigate the relationship between classroom environmental variables (that is, physical classroom environment, availability of reading materials, teacher support during reading instruction) and reading engagement among students with learning disabilities in junior secondary schools (JSS) in Ibadan, Nigeria. The…

From leading authorities, this indispensable work is now in a revised and expanded second edition, presenting state-of-the-art tools and procedures for practitioners. The book shows how to use response to intervention (RTI) to evaluate K-12 students for specific learning disabilities (SLD). The second edition gives increased attention to…

Universal screening is a critical component of school-based prevention systems. Screening data enable educators to target students for supplemental intervention, align resources to meet needs, and identify students who may be at risk for learning disabilities. One major requirement of the screening process is that all students are included to gain…

In this technical report, implementation strategies from the first two years of Project ICEBERG exploration are described. Over this period of time, a new preschool assessment, curricular activity, and teacher training tool called the Learning Receptiveness Assessment-Greenhouse application, was iteratively developed, refined, and piloted to…

The World Health Organization and World Bank (2011) estimate that there are more than 1 billion people with disabilities in the world. To address this population's diverse needs, the United Nations drafted their Convention on the Rights of Persons with Disabilities (CRPD) in 2006. Article 24 (Education) of the CRPD requires ratifying countries to…

This article provides a timely response in regard to the Department of Health's current initiative to financially reward GPs to prioritise and undertake dementia screening for people with learning disabilities over the age of 50 years and for people with Down syndrome over the age of 40 years. Whilst GPs are becoming increasingly aware of their…

When visual impairments (VI) and learning disabilities (LD) coexist, it is common for one (i.e., typically LD) to go unidentified. Some school districts may be reluctant to identify students with both VI and LD, potentially causing students to miss out on much-needed services. Child study teams can find support to address this dual diagnosis using…

Tools for assessing decoding skill in students attending elementary grades are of fundamental importance for guaranteeing an early identification of reading disabled students and reducing both the primary negative effects (on learning) and the secondary negative effects (on the development of the personality) of this disability. This article…
