This paper examines the institutional influences on the teaching-learning practices within English as Second Language (ESL) programme in the University of Sindh (UoS), Pakistan. The study uses qualitative case study approach, basing its findings on documentary review, observations, and responses of teachers and students. The analysis of the data is informed by Bourdieusian notions of "habitus," "field" and "capital." The study found that UoS's institutional policies and practices are shaped by its position in the field of higher education, which shape ESL teaching-learning practices. Specifically, UoS defines its "capital" as "higher education for all", which in practice translates as admitting students from disadvantage groups. To meet English language needs of these students, UoS offers the ESL programme. However, teaching-learning practices of ESL are significantly influenced by UoS's policies related to faculty hiring and development, ESL teachers and administration relationships, teacher-student ratio, assessment, quality assurance, and learning support resources.
