AbstractStudent–teacher gender congruence is suggested to be related to increased student performance, but little is known about the contexts in which these effects occur. Based on literature on gender stereotypes this study hypothesizes different effects of student–teacher gender congruence for male and female students across school subjects and in different educational contexts. Using administrative data of secondary schools in The Netherlands (N > 50,000), this study examined to what extent student–teacher gender congruence is associated with male and female students’ performance in the subjects math, physics, Dutch language, and French language. Further this study explored the role of students’ educational level, schools’ religiousness, and schools’ location in these relations. As expected, we found that gender congruence was positively related to female students’ performance in math and physics and to male students’ performance in Dutch language and French language. However, the role of educational context differed for male and female students across subjects and lacked a clear pattern that corresponded to the gender stereotypes hypotheses. This study emphasizes that effects of student–teacher gender congruence can differ in magnitude and direction in different contexts, encouraging future research to use qualitative methods to examine how context influences the role of gender in education.
