This autoethnography explores my experience as a bilingual teacher educator on the Texas, United States-Mexico border supporting the development of preservice teachers' pedagogical Spanish language competencies through a course that I have been developing over the last few years. To this aim, I look at my positionality and experiences developing my bilingualism in the same border community and my pedagogical Spanish language competence. My goal is to suggest how teacher education can support the development of bilingual teacher candidates' Spanish language competence in ways that recognize the linguistic diversity of border communities, critically unpack hegemonic ideologies, and prepare teacher candidates to feel confident in meeting the linguistic and academic demands and realities of the bilingual classroom.
