The role of English as a second language (ESL) teachers and instruction as factors in student social and psychological acculturation is widely acknowledged. However, the function of English for Academic Purposes (EAP) is less well known in this regard, because research has focused largely on academic acculturation. This qualitative study investigated the perceptions of curriculum alignment with undergraduate study by post-EAP learners (students who had successfully completed EAP and were registered in mainstream university programs). Semistructured interviews were conducted with 7 former EAP students from a range of faculties at a large Canadian university. Analysis of interview data highlighted social acculturation as a perceived need in EAP curriculum, as participants remarked on linguistic and cultural barriers faced while participating in university life post-EAP. The researchers argue that social acculturation is typically underrepresented in EAP curriculum, and may be inadvertently overlooked by instructors, curriculum planners, and program providers.
