This research investigated the correlations among the clinical training, mock examination, and the national physical therapy examination scores of physical therapy students, and their self-directed learning readiness, and tried to identify national physical therapy examination related factors. [Participants and Methods] The subjects were 36 third-graders of a three-year physical therapy professional training college in April 2019. Correlation analysis and multiple regression analysis were performed on the research items. [Results] Scores of the national physical therapy examination positively correlated with those of clinical training, all mock examinations, and self-directed learning readiness. Multiple regression analysis identified the fourth mock examination and selfdirected learning readiness factors were related to the score in the national physical therapy examination. [Conclusion] This study revealed that self-directed learning readiness positively correlated with the national physical therapy examination scores, and is also a factor related to the national physical therapy examination score.
