In this article, we argue for a coalitional orientation for writing programs and centers to advance language justice and make good on the promises delineated over fifty years ago in the Conference of College Composition and Communication’s publication of the Students’ Right to Their Own Language. Specifically, we argue that writing centers are ripe sites of teaching and learning—not merely auxiliary support for the composition classroom. Indeed, as we demonstrate, many writing centers actively push for language justice by, for example, publishing language diversity/inclusion statements and championing concrete, pedagogically just practices. Accordingly, we urge the discipline of composition and writing centers to work together as coalitional partners to advance language justice across the discipline and, ultimately, beyond.
