Here's the citation for the article I mentioned in today's meeting when we discussed Tom's question about what research had been done on institutional expectation of WPAs:
Olson, Gary A., and Joseph M. Moxley. "Directing Freshman Composition:
The Limits of Authority." College Composition and Communication
40.1 (February 1989): 51- 59.
Olson and Moxley did a survey of English department chairs, asking them about the perceptions of the WPA's role.
