This study aims to examine the different communication strategies (CSs) EFL learners employ when communicating orally, and determine the relationship between the learners' proficiency level and their CS use. Spoken data from three conversations held by Spanish learners of English of different levels were analysed in order to determine the type of CSs they used when interacting with a native speaker (NS) in an informal environment outside the classroom. The identification of the CSs was carried out following Dornyei and Kormos' taxonomy (1998). Overall results show that there is an association between the learners' proficiency level and their CS usage. Results from a detailed analysis confirmed this relationship and revealed that the learners' linguistic competence is not only related to the frequency of the CSs used but mostly to the type of CS.
