This article describes the development of an advanced ESL composition course, a bridge course to Freshman Composition, which is delivered almost totally on-line via the WebCT course management system. The course, Composition for International Students, is offered at an urban community college that enrolls approximately 33,000 students in the Southwest United States. In addition, the efficacy of the on-line course is compared with the face-to-face method of instruction through the seven semesters the course has been offered.
