Abstract
As writing across the curriculum (WAC) has matured and diversified as a concept and as an organizational structure in U.S. higher education, there has arisen a need for accurate, up-to-date information on the presence and characteristics of WAC and writing-in-the-disciplines (WID) programs. Following on the only previous nationwide survey of WAC/WID in 1987, new data from the U.S./Canada survey of the International WAC/WID Mapping Project indicate that the presence of such programs has grown in U.S. institutions by roughly one-third. Moreover, clear patterns emerge regarding the formal components of these programs, their intra-institutional relationships, funding sources, reporting lines, and characteristics of leadership (e.g., faculty rank and length of service). Further, a comparison of data from all reporting institutions with those from well-established programs indicates some patterns of sustainability.
