The long-term influences of ability mixing on soft skills

초록

This study examines the effect of ability mixing (as opposed to ability grouping) in sec-ondary education on long-term personality development. To address endogeneity and se-lection issues, we exploit a high school education reform implemented in Korea in the 1970s. This reform is the change in the admission system of general high school from abil-ity grouping to ability mixing. The results show that ability mixing has significant influ-ences on some personalities in adulthood. In particular, mixing treatment decreases agree-ableness and conscientiousness. We also find that these impacts on personalities are more pronounced among females. (c) 2021 Elsevier B.V. All rights reserved.
