According to the results, it is revealed that there is a positive relationship between students’ critical thinking levels and their academic achievement levels. it is observed that besides, a positive correlation was observed between students' academic achievements and their tendency to be careful about potentially problematic situations in their critical thinking skills sub-dimensions and to use objective evidence even in the face of difficult problems.
