本研究之主旨為探討恆毅力、自我控制與五大人格的盡責向度對學業成就的個別影響力及共同的影響力。研究參與者為兩百零九位技術型高中三年級學生填寫自我評估問卷，內容包含恆毅力、自我控制、盡責及對於學業成就的評估與實際獲得成績。
研究結果顯示恆毅力、自我控制與盡責間仍相互呈現顯著高度的相關，顯示個構念有相當程度的重疊。
學生對於英文、數學兩個學科之在意程度與實際成績有相關，國文科則相關不顯著。
恆毅力總分、興趣穩定性分量表與學生的學科成績呈現顯著相關。盡責與自我控制與學科成績均無呈現顯著相關。
最後恆毅力、自我控制與盡責對於學科的單獨影響力，國文、英文兩科均為恆毅力最大而盡責影響力最小，數學則是恆毅力影響力最大，影響力最小的變項是自我控制。研究結果也得到三個變項對於學科的總影響力落在3% ～4% 之間。
後續，將依研究結果，針對相關的輔導建議、本研究的限制與未來方向進行討論。

The purpose of this study is to investigate the individual and collective influences of grit, self-control, and conscientiousness on academic achievement.
Research participants filled out self-assessment questionnaires for technical high school third-year students (N = 209), which included grit, self-control, conscientiousness dimension, and the evaluation of academic performance and actual achievement.
The results of the study confirmed that grit, self-control, and conscientiousness were still significantly correlated with each other. The students’ attention to English and mathematics is related to their actual grades, but the correlation is not significant in Chinese subjects.
In addition, the total score of girt and the consistency of interest subscale were significantly correlated with students' academic performance. There was no significant correlation between conscientiousness and self-control with academic performance.
Finally, grit, self-control, and conscientiousness have individual influences on subjects. Both Chinese and English subjects have the greatest grit and the least conscientious influence. In mathematics, grit has the greatest influence, and the least influential variable is self-control. The research results also show that the total influence of the three variables on the subject falls between 3% and 4%.
In the follow-up, according to the research results, relevant counseling suggestions, limitations of this research, and future directions will be discussed.
