In 2004, the University of Kansas (KU) launched an interdisciplinary Graduate Writing Program as part of a larger initiative to reduce time to degree rates and increase degree completion rates. Serving both domestic and international students, this program employs a rhetorical genre-based approach in a series of courses organized around the genres of graduate school and beyond. In these Graduate Studies courses, students become ethnographers of the research and writing practices of their disciplines while writing their own texts and developing their professional identities. In addition, the Graduate Writing Program fields a Summer Writing Institute and offers workshops for students. The program supports departments and faculty members through consultations and workshops on such topics as how to mentor graduate writing. This profile--part program description, part theoretical construct--outlines the history and structure of the program as well as the academic and cultural challenges that graduate students and their mentors face. It argues that rhetorical genre studies is ideally suited for teaching graduate writing and supporting students as they create their professional identities.
