Writing centers can be staffed wholly or partially by tutors with little training in science writing. This article suggests that an emphasis on scientific rhetoric, not content, may be most useful for training tutors and developing handouts and checklists to aid novice science writers in invention and revision. The article also suggests that a training program in science writing can be informed by local science faculty's major concerns. However, these faculty discussions toward tutor training should be supplemented through WAC-WID and genre research to retain a training focus on the connection between scientific thought and scientific writing, science writings' primary genre families, and the delivery of scientific writing to different audiences.
