Leaving school for a period of time can have significant effects on students’ academic success. In this article, we analyze how taking an academic break for a different number of semesters affects students’ academic performance in terms of their Grade Point Average. This study is conducted at a university in Korea by analysing academic records of 653 undergraduate students who entered the university from 1998 to 2013. In addition, 101 currently enrolled students were surveyed to collect students’ opinions on the effects of academic breaks. We investigate changes in grades before and after a school leave and compare the final grades of students who had academic breaks to students who continued their studies without having any breaks during their undergraduate education.Our results indicate that students’ grades improve after coming back to the university from a four or more consecutive semesters break, however their final GPAs did not statistically differ from their peers who studied continuously, this suggests that students should not be afraid of taking longer academic breaks.
