This study examined what kinds of groups can be identified according to students' task-values across four subject domains (languages, math and science, social sciences, practical subjects) and the related gender differences using a person-centered approach. Latent class analysis was applied to classify 638 students (mean age = 15) into four task-value groups, namely, "all-subjects" (55%), "practical-subjects" (5.7%), "high-math-and-science" (20.2%) and "low-math-and-science" (19.1%) groups. Significant gender differences were found: boys dominated the "high-math-and-science" group (boys = 98%), while girls dominated the "low-math-and-science" group (girls = 82%). Compared to the "low-math-and-science" group, the "high-math-and-science" group reported a stronger tendency in furthering their studies immediately after the completion of compulsory education.
