Multimodal composition is becoming increasingly popular in university classrooms as faculty, students, and institutions come to recognize that old and new technologies have enabled, and even demanded, the use of more than one composing mode for communicating, solving problems, and keeping up with the latest discourse. Professionalizing Multimodal Composition embraces and enacts multimodal composition in various writing courses and programs by exploring institutional, programmatic, and individual faculty initiatives for capacity building and human resource development across institutions.  Academic leaders, scholars, and faculty who have successfully designed and launched academic programs or faculty development initiatives discuss the theoretical and logistical questions considered in their design, the outcomes they achieved, and how others can emulate them. This exchange of knowledge, insight, experiences, and lessons learned among community members is critical for enabling or inspiring other programs, departments, and institutions to conceive, design, and launch academic programs or faculty development initiatives for their own faculty.  The larger goal of professionalizing is to work with teaching faculty to increase their interactional expertise with multimodal composition, and this collection offers a set of models for how faculty can do that at their own institutions and in their own programs.
