On the fi rst day of the semester, twenty-fi ve students eagerly await their freshman composition instructor' s arrival. A glance around the classroom reveals a wide array of differences among the students. Blacks, whites, Latinas/os, and Asians all populate the classroom. A dually enrolled high school student chats with a grandmother in her fi fties. Some students busily text and tweet their friends; others have never sent an e-mail. At least two students speak English as a second or other language, and one individual has a documented learning disability. Some students have arrived academically prepared for college-level writing, yet many have only recently completed developmental course work designed to prepare them for the rigor of the general education curriculum. Still others will require long hours of tutoring, mentoring, and student-teacher conferences to learn to write profi ciently.Such diversity is the norm at America' s community colleges, which, as open-door institutions, serve the most widely varied group of students in higher education. The community college teacher who enters that freshman composition class must know more than her discipline; she must possess the ability to engage and encourage, motivate and inspire, teach and learn from her diverse students. To educate learners with vastly different backgrounds, abilities, and levels of academic preparedness, community colleges need the best teachers available in the academic labor market. Hiring exemplary instructors is at once an educational and an economic imperative, for the typical "community college spends over $3 million on the career of one faculty member" (Flannigan, Jones, and Moore, 2004,
