The Association of Two-Way & Dual Language Education (ATDLE) was formed into a national organization in 2013. It had previously existed as Two-Way CABE for over ten years. The Board of Directors found it necessary to move from a state organization to a national organization to mitigate the development of programs throughout the U.S.A. In 2017, there are over 1800 Dual Language and Two-Way Bilingual Immersion programs in the country in five different languages: Spanish, Mandarin, Korean, Spanish and Japanese.

As the leading organization in Two-Way Bilingual Immersion Education, we work closely with other organizations and agencies that share a common vision and mission for this work. These agencies form the National Dual Language Consortium to support the development and continued implementation of Two-Way & Dual Language programs throughout the United States. The Center for Applied Linguistics (CAL), Dual Language Education New Mexico and others work to provide quality training and support as programs develop in their respective communities.

The ATDLE team provides focused and relevant professional training opportunities for new and existing programs! Our commitment to excellence in education through second and third language education is unwavering. We believe strongly in quality implementation and the full implementation of research-based practices. We lead the charge by utilizing the amazing expertise of some of the most experienced programmatic experts in TWBI/DL and know that we can be of great service to teachers, administrators and program development leads wanting to start their programs or improve their practice!
