Exceptional education, also known as special education, is often grounded within exclusive and deficit mindsets and practices. Research has shown perpetual challenges with disproportionate identification of culturally and linguistically diverse students, especially Black and Indigenous students. Research has also shown perpetual use of inappropriate placement in more restrictive learning environments for marginalized students, often starting in Pre-K. Exceptional education practitioners often engage in practices that place disability before ability in instruction, behavior management, identification and use of related services, and educational setting placement decisions. These practices, among others, have resulted in a crippled system that situates students with exceptionalities in perceptions of deviance, ineptitude, and perpetuate systemic oppression.The Handbook of Research on Challenging Deficit Thinking for Exceptional Education Improvement unites current theory and practices to communicate the next steps to end the current harmful practices and experiences of exceptional students through critical analysis of current practices, mindsets, and policies. With the information this book provides, practitioners have the power to implement direct and explicit actions across levels to end the harm and liberate our most vulnerable populations. Covering topics such as accelerated learning, educator preparation programs, and intersectional perspectives, this book is a dynamic resource for teachers in exceptional education, general teachers, social workers, psychologists, educational leaders, organizational leaders, the criminal justice system, law enforcement agencies, government agencies, policymakers, curriculum designers, testing companies, current educational practitioners, administrators, post-grad students, professors, researchers, and academicians.
