Scholars in writing studies have positioned numerous critiques of the tacit myth of Standard English (*SE) and its use as an unquestioned communicative norm. While these critiques reflect the overlap of the field's translingualism and anti-racist writing assessment movements, they also reveal an empirical need surrounding the writing instructors who must actually grapple with the *SE myth in their teaching and grading practices. Following Asao Inoue's identification of the *SE myth as a slick eel that remains an assessment problem, I conducted a qualitative study using concept clarification interviews and discourse-based interviews (DBIs) at a large, diverse, four-year university in the U.S. to empirically confront the *SE myth and make the potentially tacit presence of *SE in instructors' rubrics and grading practices explicit. Based on the results of these interviews, I advocate for a shift from seeing and critiquing *SE to performing Synergistic English Work (SEW) in the context of grading rubrics and assessment policies, making the absent presence of *SE visible, open to disruption, and more actively combatted.
