This study considers the potential for translanguaging to disrupt monolingual ideologies through development of in-service teachers' (ISTs) translanguaging stance. Using discourse analysis, we examined learning outcomes among five ISTs to consider what ideological constraints limited their adoption of a translanguaging stance and how, if at all, they moved beyond these constraints. Findings highlight micro-, meso-, and macrolevel influences that constrained ISTs' adoption of translanguaging and the productive ways they imagined addressing these limitations. Included are implications for how teacher education might support teachers in adopting a translanguaging stance.
