Abstarct: The difficulty of learning a second/foreign language and also the shortage of time as well as the increase in language learning costs leads us towards discovering the effective techniques of fostering learner autonomy. Although some techniques have been frequently explored by previous studies, none of them was conducted empirically through the voice of language teachers in Iran. The current study aims at exploring teachers' techniques and methods on fostering learner autonomy. By grounded theory, the researcher theoretically sampled concepts through interviewing at least 16 teachers who taught English either in public or private language schools or just in private schools. The interviews were audiotaped, transcribed, and analyzed by applying open coding, selective coding, and axial coding. In a cyclical process of data collection and analysis, the researchers found the effectiveness of learner autonomy techniques presented by the teachers in order to lead learners towards autonomous learning in the class and out of it. Some of the techniques are new in the body of the knowledge and the results are applicable to the educational system, both public and private language schools, EFL learners, and EFL teachers in Iran.
