Professional isolation, a familiar issue in world language education, has been exacerbated by the COVID-19 pandemic. This article addresses this issue by providing world language educators with practical guidance related to establishing high-functioning professional networks online. Empirical findings related to computer-mediated communication (CMC) in language learning and teacher training contexts support the articulation of four critical considerations for successful online professional communities: that participants (a) possess requisite technical knowledge to navigate the platforms being utilized; (b) develop requisite reflective and evaluative competencies; (c) exhibit ongoing, sustained engagement; and (d) engage collaboratively with other participants. In concert, successful treatment of these considerations not only provides practitioners with a temporary solution to engage in physically distant collaboration, but also may help establish a more robust, sustainable professional development infrastructure for world language teachers in the future.
