This of course leads to the academic performance that will be produced. This research was conducted with the aim of knowing the dynamics of grit in student academic performance. The method used in this research is a type of qualitative research with a systematic literature review. The research design is in the form of SPIDER (sample, phenomenon of consistency of interest, design, evaluation, and research type) with the final number of articles used being 16. The results of the research show that grit and academic performance are known to have varying relationships which can be grouped into four relationships, namely significant positive, as a predictor, as a moderator, until there is no relationship between the two. In each relationship that has been mentioned, grit has its own role in the dynamics of academic performance. Based on the two dimensions of grit, persistence of effort is known to have a higher significance than consistency of interest in its influence on student academic performance.
