This case study reports how three high-school teachers from two state schools in Colombia enacted the National English Suggested Curriculum by the Ministry of Education. The teachers' trajectories of action were analyzed through semi-structured interviews, teachers' narratives, and lesson observations. Using the ecological model of agency as a framework, we situated teachers' steps within projective, iterational, and practical evaluative dimensions of agency. In this paper, we provide additional dimensions of teacher agency, which can help to expand theoretical and empirical knowledge in the field. Findings show that teachers cope with the changes derived from policy differently. The analysis presented in this paper can inform the creation and promotion of future curriculum policies in similar contexts.
