Data on the impact of student, teacher, and principal racial and gender composition in urban schools on teacher work outcomes are limited. This study, a secondary data analysis of White and Black urban public school teachers using data taken from the restricted use 2003-04 Schools and Staffing Survey (SASS), examines the effects of relational demography on teacher job satisfaction adjusting for other known determinants of job satisfaction. Relational demography is conceptualized as a set of racial and gender congruency items between teachers and principals, teachers and teachers, and teachers and students. The results of the study show that some components of relational demography directly affect teacher job satisfaction, over and above the effects of work-related attitudes. (Contains 4 tables.)
