This paper investigates the relationship between Angela Duckworth’s (Duckworth, Peterson, Matthews, and Kelly, 2007) concept of grit and academic performance in mathematics, with attention to the performance of students with low grit scores. Research thus far has been inconclusive about the relationship between grit and performance, but the authors of this paper noticed that students with the lowest grit scores seemed to be generally high performers, and so they conducted a simple action research study to investigate. Results indicated that students with the lowest grit scores performed as well as students with high grit scores. The authors attempt to describe these students who have low grit, yet demonstrate high academic performance.
