English as an International Language


English is a vibrant and international language with twenty percent of the world’s population speaking English as native, second or foreign language. In addition to its status as a mother tongue in many countries, global use of English is growing for communication among speakers of other languages in places where English is not the majority language. Non-native speakers (950 million) outnumber native speakers (430 million) by more than two to one. 

As interest in English as a second language grows around the world, CAL is engaging in a wide range of activities in and for other countries, including assessment and curriculum development, teacher professional development and training, evaluation, and other program services.
