Subjects in this study were Wushu Sanda athletes who participated in the 2017 North Sumatra Regional Championship. The measuring instrument used in this study was the success of athletes reaching the final round, the scale of achievement motivation, and the scale of self-confidence. Research Hypothesis: There is an influence of achievement motivation and self-confidence on athletes’ achievements in the North Sumatra Wushu Sanda Regional Championship. The analysis used logistic regression. The results of the analysis show that the equation model can be accepted with the results of the Hosmer and Lemeshow Test of 0.920 (> 0.05). Nagelkerke R Square statistic of 0.201 shows the ability of achievement motivation and self-confidence variables to explain athlete achievement by 20.1%. This means that there are other factors that can give more effect on the achievements of Wushu Sanda athletes who were not defined in this study. This might occur because of other psychological aspects that affect the match situation such as emotional regulation, strategy in dealing with opponents, concentration, and others. Thus it is recommended to conduct research with other psychological aspects to see the influence on achievement in the competition.
