In South Korea, college-bound students are divided into two tracks: "Munka" (??) and "Yika" (??), and this tracking ("Munka-Yika" tracking; MY tracking) considerably influences students' choice of college majors and future careers. This study aims to examine how MY tracking and other factors influence students' postsecondary enrollment (2- or 4-year colleges) and college major choice (vocationally or academically oriented). The findings indicate that there was no significant effect of MY tracking on students' choice of a type of colleges, but the "Yika" students were more likely to study vocationally oriented majors more often than the "Munka" students. Male students had a higher probability of going to 4-year colleges and studying vocationally oriented majors than female students. Academic performance in high schools and fathers' education levels contributed to students' enrollment at 4-year colleges, and conversations with parents about academic or career plans influenced students choice of vocationally oriented majors.
