Writing center consultant training must account for the multiple media and modes students use as they compose on new digital platforms. While most consultants come to writing center work already confident in traditional literacies, to advise on multimodal projects, they also need to understand how elements such as visual design, navigability, and accessibility play into the rhetorical situation. Starting in 2021, our writing center assigned an ePortfolio-focused professional development curriculum to our consultants, culminating with their creation of websites that integrated and showcased their knowledge, skills, and abilities. The authors studied the consultants’ responses over the first two years of implementation, collecting data from surveys, session observations, and interviews, which we analyzed through inductive and deductive coding. Our results indicate that consultants advanced their understanding of multimodality through their participation in the ePortfolio curriculum and applied their learning in consultations not only about ePortfolios, but also about other visually rich media and application materials. Other writing centers may consider incorporating ePortfolios into their tutor development programs.
