The study also verified the correlation between parents' education levels, family economic background, grit total, consistency of interest, and perseverance of effort. This research is field research with a quantitative approach. The participants amounted to 267 students of Antasari State Islamic University. Convenience techniques and snowballing sampling determined participants. Researchers used descriptive statistics, the Mann-Whitney U, Kruskal Wallis H, and Spearman's Rank Correlation test to analyze the data. The results showed no significant differences in total grit levels and its aspects between gender and ethnicity (Sig.>0.005). Dayak ethnic minorities are more persistent and grittier than the majority ethnicity, Banjar, but not significant. Parental education does not correlate with total grit and both aspects. The influence of gender, ethnicity, and socio-economic background on grit is also determined by the type of education students attend.
