The purpose of this study is to explore the employability of the Department of Mechanical Engineering of the National Science and Technology School after graduation, and to study the employers of social freshmen and machinery-related enterprises who graduated from the Department of Mechanical Engineering within five years. with regard to mechanical related abilities, general common abilities, and behavioral attitudes. The correlation between the three major employment performances. The research target is 123 fresh people from the country who have graduated within five years of student and 112 employers people from all over the country. Graduates use Employability Table for Mechanical and Mechanical College Graduation in Science and Technology Colleges self-assessment of core employability performance. The Employers uses Employability Table for Mechanical and Mechanical College Graduation in Science and Technology Colleges to assess the graduates’ employment performance. The results of the study show that there are significant differences between graduates and employers in terms of the three major employability-oriented items, and the scores of graduates are generally higher than those of employer. Finally, based on the research findings, this study proposes relevant suggestions for improving the core employment and future research of college students.
