This paper examines the development of strategy use over 6 months in two lower-intermediate learners of L2 French in secondary schools in England. These learners were selected from a larger sample on the basis of their scores on a recall protocol completed after listening to short passages at two time points: one was consistently a high scorer; the other one, a low scorer. Qualitative data on these two learners' strategic behaviour were gathered at the two time points from verbal reports made by learners while they were completing a multiple-choice listening task. Our results show a high degree of stability of strategy use over the time period, with pre-existing differences between the high and low scorer persisting. The theoretical and pedagogical implications of these findings are discussed. (Contains 1 figure and 1 table.)
