This article seeks to address the need for research supporting localization efforts in placement assessment. We argue that as a highly technical communication endeavor, directed self-placement (DSP) and its developers can benefit from research in technical and professional communication (TPC). We synthesize the theoretical relations between DSP and TPC, especially regarding models of localization, and demonstrate how implementing user experience (UX) design can help address placement equity concerns by foregrounding accessibility and usability from the beginning. We follow this discussion of DSP and TPC scholarship with storied examples from our institution, providing a sample range of UX methods that (1) are flexible across contexts, (2) are relatively manageable to implement, and (3) are cognizant of WPA, staff, and students’ time, labor, and compensation concerns. We propose DSP as a form of advocacy, and we demonstrate how UX method/ologies are an excellent choice for DSP localization efforts toward equity and accessibility.
