Racial and Ethnic Heterogeneity in the Effect of MESA on AP STEM Coursework and College STEM Major Aspirations

-MESA participation increases students’ odds of taking AP STEM courses in high school and their aspirations for declaring a STEM major in college.
– These effects are driven primarily by black and white students, respectively.
– Latino and Asian students remain largely unaffected by MESA partiipation.
– MESA may improve black students’ high school STEM engagement but may have little impact on black and Latino students’ STEM outcomes in college.
