This article empirically studies the impact of perseverance and passion for long term goals (GRIT) on educational achievements. Specifically, the study compares GRIT levels between migrants and native school students, and tests the role of GRIT in explaining school achievements of migrants. Based on regression analysis and using a sample of 2,003 ninth graders, including 178 migrants from the Republic of Tatarstan, Russia, the results did not suggest an educational gap between native students and first generation migrants, ethnic Tatar migrants, and those from Central Asia. In addition, GRIT has significant effects in explaining the educational achievements of these migrant groups. On the contrary, the findings suggest that native students outperform their ethnic Russian migrant peers.
