Collaborative online international learning (COIL) has grown as an innovative technology-enhanced education approach with great potential for language education. Among the different COIL initiatives, eTwinning offers opportunities for language teachers and learners. Considering the limited research about pre-service language teachers’ digital literacy who have participated in the eTwinning for future teachers initiative, this paper’s objective is to explore how eTwinning can enhance teachers’ digital skills involving pre-service language teachers (N=76) from two European universities, University of Cordoba, UCO (Spain) and University of Lower Silesia, ULS (Poland). The study follows a quantitative approach, using an exploratory cross-sectional method and an interpretative approach. The results show a general positive perception of participants from both contexts, while there are statistically significant differences regarding gender and university. Finally, the paper reflects on how to use eTwinning to improve teachers’ digital literacy.
