English teachers’ professional development responds to individual needs and societal discourses about teaching, learning, and language use. This paper reports the findings of a case study that explored the factors that increased or limited the active and committed participation of nine Colombian teachers of English in professional development programs. Findings suggest that English teachers are invested in their professional development if they may develop three imagined identities—as proficient English speakers, ELT experts, and ICT competent users—and their affiliation to an imagined community of “bilinguals.” The teachers’ journey to the imagined identities and the imagined community is full of conflicting emotions amidst the socio-political context of their work and the country’s language education policies.

The professional development of English teachers is a significant area in language teaching and learning, as well as in teacher education. On the one hand, at least in theory, professional development initiatives respond to the teachers’ changing needs. On the other hand, it reflects the beliefs that different educational authorities and stakeholders have about English uses and education. In this self-study, I consider the professional development of English teachers in Colombia and its tight connection to the language education policies of the country. Following a chronological approach, I present the findings as landmarks that have contributed to my reflections and research around professional development and language education policies. Discussing the findings, I show how the discourses and decisions about teachers’ continuing learning represent certain views of language, second language acquisition, English language teaching and learning, and teachers as professionals. This self-study addresses some of the concepts that illuminate the discourses that have shaped English teachers’ professional development. Focusing primarily on the development of the National Program of Bilingualism, I underscore the power of these concepts over the major decisions made at the local and school levels. In the analysis of the past and present of teachers’ professional development in Colombia, I conclude on the necessity of maintaining critical scholarly work to contribute to the construction of local knowledge for future reflection.
