This article focuses on the experiences of Grade 12 students using a language portfolio based on the principles and guidelines of the European Language Portfolio (ELP) in their second language classes in a large urban high school. As part of a larger action-research project, focus group interviews were conducted to gather data related to experiences and perceptions regarding second language learning. In particular, the research questions focused on the learners' experiences with the language portfolio and its potential role in contributing to learner autonomy. Three overarching themes emerged from the data collected from learners who participated in this study. These themes related to general perceptions of learning, to language learning experiences, and to experiences with the language portfolio. The article concludes with a discussion of the pedagogical linkages to learner autonomy and suggests implications for educators who wish to promote learner autonomy.
