This study compares the relative effectiveness of private tutoring and self-directed learning on the formation of cognitive (academic achievement on Korean, math, and English) and noncognitive skills (friendship, self esteem, creative personality, and motivation) of primary and secondary school students in Seoul. The results show that private tutoring has positive but diminishing effects on cognitive skill formation with no effects on noncognitive skill formation, while self-directed learning has positive effects on both cognitive and noncognitive skill formation.
