As part of a larger study (Rahimi, 2004), this study investigates the use of language learning strategies by post-secondary level Persian EFL learners. Particular attention is paid to the variables affecting learners' choice of strategies, and the relationship, if any, between these variables and learners' patterns of strategy use. Data were gathered from 196 low-, mid- and high-proficiency learners using such instruments as the Strategy Inventory for Language Learning (SILL; Oxford, 1990), and two questionnaires of attitude and motivation (adapted from Laine, 1988) and learning style (Soloman and Felder, 2001). The results of the study point to proficiency level and motivation as major predictors of the use of language learning strategies among this group of learners. Gender, on the other hand, is not found to have any effect while years of language study appear to negatively predict strategy use. The difference between learners' use of the SILL's six major strategy categories is found to be significant and indicates learners' preference for metacognitive strategies.
