Given that a number of studies have documented the wide-ranging benefits of academic engagement and help-seeking, how they can be improved is an important issue in college education. This study explored the relationship between the growth mindset, grit, academic engagement, and help-seeking of community college students. To do so, we conducted online surveys and analyzed data from 423 out of 441 community college students. We used SPSS 21 to perform pre-analyses and employed structural equation modeling with Amos 21 to verify the hypotheses in this study. The results from the pre-analyses show that all of the variables in this study positively correlated with one another. Results from the structural equation modeling are as follows. First, students’ growth mindset positively correlated with help-seeking, whereas it did not directly correlate with academic engagement. Second, grit fully mediated the relation between students’ growth mindset and academic engagement, and between their growth mindset and help-seeking. These findings help us understand how growth mindset and grit can work as noncognitive factors that affect students’ academic engagement and help-seeking, which leads to a path of academic success. Finally, theoretical and practical implications are discussed.
