The aim of this study; is to examine the critical thinking dispositions and achievement goal orientations of university students in terms of various variables, and to determine the predictive level of students' critical thinking dispositions on their achievement goal orientations. The sample of the research consists of 785 (333 female, 452 male) university students studying at Sivas Cumhuriyet University in the spring semester of 2021-2022 academic year. The study group of the research was determined by the random sampling method, which is one of the screening methods. "California Critical Thinking Disposition Scale" and "Achievement Goal Orientations Scale" were used to obtain the research data. Descriptive and normality analysis, independent sample t-test, one-way ANOVA, Tukey and multiple regression analysis were used to obtain the data. In the findings obtained, students' critical thinking dispositions were related to the variables of grade level, income status, and graduated school type; on the other hand, it was determined that achievement goal orientations differed statistically significantly according to the type of program studied, class level, income status, and type of school graduated. In addition, it was determined that the change in the sub-dimensions of the critical thinking dispositions scale explained the learning/approach goal orientation by 12.2%, the learning/avoidance goal orientation by 12.6%, the performance/approach goal orientation by about 10.6%, and the performance/avoidance goal orientation by about 15.2%.
