Multifactorial models of dyslexia have expanded how we consider heterogeneity within the population of children with dyslexia. These models are predicated on the idea that cognitive/linguistic risk factors are not deterministic but instead probabilistic, with the likelihood of difficulties involving an interaction between risk and protective…

The Individuals with Disabilities Education Improvement Act (2004) allows alternate pathways for school districts to identify and classify students with a specific learning disability (SLD). Response to Intervention (RtI) is one of the frameworks schools can use when eliminating the use of the discrepancy model. The premise of RtI posits that…

Teachers in today's society are having increasing difficulties with Individualized Education Program (IEP) implementation because teachers struggle with assessing data, designing instruction to fit individual needs, providing accommodations, and working as a team with a general education teacher in a co-teaching environment (Cawthon, 2009; Kosko…

This chapter examines how studies focused on the same topic--disproportionality in special education--can generate vastly different conclusions about its sources and causes. By analyzing existing disagreements in the field, we explore essential questions about what constitutes high-quality and relevant evidence when seeking to understand how,…

This brief, co-produced by the National Center on Deaf-Blindness (NCDB) and Accessible Teaching, Learning, and Assessment Systems (ATLAS), provides important information about students with dual sensory loss who also have significant cognitive disabilities, as well as recommendations for identification and implications for instruction. The…
