The purpose of this study was to provide evidence of validity to apply the Triarchic Grit Scale(TGS) of Jung(2019) to Taekwondo athletes through the Rasch model. 587 Taekwondo athletes were asked to respond to the TGS consisting of 3 factors 15 items. Factor structure determination and unidimensionality assumption satisfaction were verified through the CFA model, and Rasch model applied the Rating Scale Model(RSM). In addition, jamovi 1.2.25 and jMetrik 4.1.1 were applied as analysis programs, and the statistical significance level was set to .05. As a result of the study, first, since the 3 factors of TGS did not show multidimensionality, it was reasonable to assume unidimensionality at the level of general factors. Second, the response category of the scale appears to have a problem, and it needs to be modified to a 4 point category instead of the existing 5 point category. Third, as a result of analyzing the item goodness-of-it, the g04 item was found to be inadequate and needs to be corrected or removed. In addition, as a result of comparing individual attribute scores and difficulty, the distribution of individual attribute scores was appropriate, but the distribution of item difficulty was shown to be biased.
