TEFLIN as a professional organization stands for the association of Teaching English as a Foreign Language in Indonesia. It was established in Jogjakarta in 1970 as a local teacher association in Central Java, but now has developed into a professional national organization and is formally acknowledged by the government.

It began with bimonthly regional one-day seminars on the teaching of English in Indonesia to be held in the English departments of private and state universities in Central Java and Yogyakarta in late 1968 or early in 1969. Early in 1980 these regional seminars were promoted as national seminars and were conducted twice a year.

Considering the fast growing global professional interest in the field of TEFL and TESL, the event was then formalized as yearly “international Seminar”. This decision was taken in a pre-executive meeting in Semarang, Central Java in 1998. In the years later, the label of the event, Seminar, is further re-formalized as the “TEFLIN International Conference”.

Nowadays, practically all English departments of state as well as private universities and most English teaching/education institutions in Indonesia join TEFLIN organization as institutional as well as individual members, and participate in the activities conducted by TEFLIN.

TEFLIN has close relationship with a number of international TEFL institutions and professional organizations such as TESOL International, IATEFL, MELTA Malaysia, Thai-TESOL Thailand, Cam-TESOL Cambodia, ALAK South Korea, JALT Japan, RELC SEAMEO Singapore, RELO Jakarta, and British Council Jakarta.

The annual TEFLIN International Conferences are regularly attended by 500 to 1000 participants from home as well as foreign countries.
