Using the technical and professional communication service course as the site for research, and student learning outcomes (SLOs) as the specific focus, we gathered, coded, and analyzed 503 SLOs from 93 institutions. Our results show the top outcomes are rhetoric, genre, writing, design, and collaboration. We discuss these outcomes and then we offer programmatic implications drawn from the data that encourage technical and professional communication program administrators and faculty to use common SLOs, to improve outcome development, and to reconsider the purpose of the service course for students.
