TESOL

The international organization TESOL (Teachers to Speakers of Other Languages) has a mission "to develop and maintain professional expertise in English language teaching and learning for speakers of other languages worldwide."

It is associated with a large number of national English teaching organisations. Individual membership costs ninety-five dollars although there are other options.

Events and conferences
They have an annual four-day conference held in the USA which aims to further their mission, and they also hold other international events.

Other uses
TESOL, by itself is also used as an acronym for Teaching English to Speakers of Other Languages.

It is often used as a synonym for TEFL, but it can also be used as a description for English language teaching to people living in an English speaking country who are not native English speakers – such as refugees and first generation immigrants.
