Students with or at-risk of High Incidence Disabilities (HID) experience negative short and long-term outcomes. To intervene, many schools have elected to implement evidence-based practices within Multi-Tiered Systems of Support (MTSS), such as Response to Intervention (RTI). MTSS target the academic and behavioral progress of students deemed 'at…

Purpose: Bayesian-based models for diagnosis are common in medicine but have not been incorporated into identification models for dyslexia. The purpose of the present study was to evaluate Bayesian identification models that included a broader set of predictors and that capitalized on recent developments in modeling the prevalence of dyslexia.…

The aims of this study were to examine speech-language pathologists' (SLPs) knowledge and consideration of factors found in research when making clinical decisions regarding AAC for children with Autism Spectrum Disorder (ASD), and to reveal additional factors identified based on SLPs' clinical practice.

In tiered instructional systems (Response to Intervention [RTI]/Multitier System of Supports [MTSS]) that rely on ongoing assessment of students at risk of experiencing academic difficulties, the ability to make informed decisions using student data is critical for student learning. Prior research has demonstrated that, on average, teachers have…

Response to intervention (RTI) is increasingly being implemented in schools as a means to identify students with specific learning disabilities (SLD). Despite its wide use, there is limited research regarding school psychologists' graduate preparation in and familiarity with RTI for SLD identification. This study examined how school psychologists'…

Questions remain regarding whether professional development focused on response to intervention can be implemented effectively on a large scale. One important goal of professional development involves educators' beliefs regarding foundational response-to-intervention concepts (e.g., data-based decision making, importance of effective instruction).…

School personnel make a variety of decisions within multitiered problem-solving frameworks, including the decision to assign a student to group-based support, to design an individualized support plan, or classify a student as eligible for special education.
