For more than 50 years, the unique needs of twice-exceptional (2e) learners have challenged educators. Because of this challenge, much work has been done in different areas across the country in creating appropriate learning environments for serving this population. However, no unified way has been developed to bring together the best research and thinking regarding practice. Most importantly, no one definition has been embraced by both researchers and practitioners. To address this issue, professional organizations and specialists in the field of twice-exceptionality formed a Community of Practice and a new definition was created. This definition and how it can be used to move the field forward is presented.
