Variations in the school-based career exploration activities of Korean high school students were examined. Data represented 5,227 Korean adolescents in Grade 11 contained in the Korean Education Longitudinal Study of 2005, a nationally representative longitudinal database administered by the Korean Educational Development Institute. Latent class analysis identified four classes or approaches reflecting some combination of school availability and student use of career-related activities, including "minimal-", "limited-", "moderate-", and "high-"activity groups. Multiple-group analysis revealed that curriculum track (i.e., vocational or academic emphasis) was an important determinant in classification.
