Culture is an integral facet of teaching and learning English as a foreign language. This qualitative study examined EFL teachers’ perceptions toward fostering their students’ cultural awareness in Iranian language schools. Based on a researcher-developed protocol, semi-structured interviews were conducted with twelve EFL teachers from Tehran, Karaj, and Urmia, Iran, whose teaching experiences ranged from 6 to 19 years, with the purpose of identifying their perceptions, experiences, and challenges regarding fostering students’ cultural awareness. The interviews drew upon emergent methodology to categorize the interviewees’ value-laden comments into six major attitudinal themes of meaning of culture, the role of English culture and social norms in EFL teaching and learning, the materials and activities teachers employ to foster their students’ cultural awareness, benefits of teaching English culture in Iranian language schools, EFL teachers’ challenges regarding teaching English culture, and teachers’ suggestions or recommendations regarding teaching culture in the Iranian EFL context. The findings illustrated that despite the fact that Iranian EFL teachers preferred to include cultural content in their courses, they faced a variety of challenges regarding teaching English culture and social norms. Further, Iranian policymakers, stakeholders, and educators are expected to provide professional training opportunities for EFL teachers in teaching English culture. Thus, teaching culture should be underscored in EFL classes and instructors are required to explore and apply various effective strategies and authentic materials to enhance their language learners’ cultural knowledge. The implications are presented and discussed in more detail in the paper.
