The aggressive internationalization of Canadian universities and increased immigration to Canada over the past 20 years have resulted in a dramatic increase in the number of second language (L2) students in Canadian universities. However, little is known about the factors that influence academic acculturation of L2 students or about the role of English for academic purposes (EAP) instruction in their acculturation process. This study examined L2 university students' perceptions of academic acculturation and the role of EAP instruction by means of interviews conducted with 56 L2 students at three Canadian universities. Findings suggest that the students who characterized their academic engagement as successful had typically developed more strategic learning and social skills as part of their acculturation process. Implications are drawn for the importance of aligning students' agendas for learning (i.e., their perceptions of needs) with EAP programs.
