With science and technology innovation driving economic growth, cultivating science and engineering talent has become a national priority. However, many students in these fields choose majors based on entrance exam scores rather than interest, leading to increased dropout rates due to academic difficulty and lack of basic skills. This study investigates how major selection motivation influences major commitment, focusing on the mediating role of grit. Specifically, it examines whether the sub-factors of grit—perseverance of effort and consistency of interest—mediate the relationship between intrinsic and extrinsic motivation and major commitment. The study surveyed 104 engineering students at K University in B city. Using SPSS 29.0, correlation analysis, hierarchical regression, and bootstrapping were conducted. The results showed that only intrinsic motivation significantly affected major commitment. In addition, perseverance of effort partially mediated the effects of both intrinsic and extrinsic motivation on major commitment. These findings suggest that fostering intrinsic motivation and enhancing students’ grit, particularly sustained effort, can be effective strategies to strengthen major commitment in engineering education.
