ABSTRACT
The current knowledge base in the area of twice exceptionality, particularly regarding those students with learning disabilities, includes both empirical research from the neurosciences and lessons from practice, where clinical and educational programs have sprouted to provide support and an organizational identity for twice exceptionality. Twice exceptionality is not a diagnosis widely accepted and supported in mainstream education. Notably, little epidemiological data exist to provide incidence or precedence for it, because it extends across several populations of disability and because no central definition exists for giftedness. However, information from empirical and epidemiological research, case studies, assessment, and current models of practice provides the fundamental knowledge necessary to advocate for and serve these special gifted children, poised to contribute to the world in extraordinary ways with their unique skills and talents.
