The purpose of this study is to identify the type of grit present in adolescents according to the two components of grit, persistence of effort and consistency of interest. In addition, the research examined what the environmental factors predict the type of grit and the differences in behavioral regulation and self-determined motivation based on the type of grit. For these purposes, the study administered 532 middle school students who are in the grade 2. As a result, grit was classified into 6 types according to the degree of two components of grit. Especially gender of students and free communication at home, and friendship in school significantly predict the classification of grit. Also, the relationship between type of grit and self - regulated learning showed that students with higher grit showed better behavioral regulation and higher intrinsic motivation, indicating that grit is related to positive learning traits. These results suggest that grit can be promoted by the environment, and that the development of grit leads to the enhancement of self-determined motivation and behavior regulation, which are necessary for adolescents.
