We exploit data from middle schools in Seoul, South Korea, where students and teachers are randomly assigned to classrooms, and find that female students taught by a female versus a male teacher score higher on standardized tests compared to male students even five years later. We also find that having a female math teacher in 7th grade increases the likelihood that female students take higher-level math courses, aspire to a STEM degree, and attend a STEM-focused high school. These effects are driven by changes in students' attitudes and choices.
