Self-access centers (SACs) became popular in Mexico in the 1990s with the purpose of allowing learners to make decisions about how to learn languages. The following study is qualitative and longitudinal and was carried out in the SAC at the University of Sonora in Mexico. It was designed with the purpose of understanding learners’ performance as they direct their own learning in a SAC. By focusing on learning experiences, activities, and materials, the results show that learners understand the idea of language learning in SACs in a limited way. However, the participants view learning in a SAC to be an effective approach to learning languages due to the progress and growth they noticed.
