In this paper I examine how and to what extent various elements of my biography--race, ethnicity, gender, age, social class background, and prior personal and professional experiences--influenced my relationships with students in a graduate course examining the impact of race, gender, and social class on education. My lived experiences as an immigrant woman of color in United States society and my prior professional experiences as an urban teacher are shown to have strengthened my expertise and confidence in teaching this course. Nevertheless, experience confirmed my initial concerns that my race, gender, and social class background negatively influenced some students' perceptions of my teaching competence and position of authority in the classroom. The paper concludes with recommendations for teacher education, including encouraging teachers to continuously engage the question of how their biographies shape their pedagogies and relationships with students, an important undertaking as our schooling populations become more racially, ethnically, and linguistically diverse. I also recommend that universities continue to recruit faculty who are not only from racial minority backgrounds but also from varied ethnic and social class backgrounds.
