In this article, I summarize an interview-based, qualitative research study conducted with ten Marine student veterans on their experiences with college composition courses, focusing particularly on the how the participants’ previous interactions with teaching, learning, and writing in the Marine Corps have impacted their perceptions and expectations of teaching, learning, and writing in the first-year composition classroom. Specifically, I focus on the way in which relevant conclusions from the study regarding Marine student veterans’ prior rhetorical knowledge and experiences complicate the novice-to-expert paradigm at work in many first-year composition courses. The piece concludes with suggestions for repurposing this paradigm to one that encourages faculty to make room for prior rhetorical knowledge while identifying areas where student veterans may need support.
