Good extracurricular activities can optimize the quality of education, fetch up with classroom education and teach them what they cannot learn from it, is conducive to improve students’ comprehensive quality, to complete the task and achieve the goal of university education. For this reason, this paper proposes an extracurricular sports lifestyle evaluation to college students via an improved ELECTRE method. In the proposed method, three indexes – concordance index, non-concordance index and credibility index – are defined first. Based on these indexes, the preference evaluation matrix is constructed, and consistent credibility, non-consistent credibility and net credibility are computed second. Third, it was sorted for the quality of all alternatives according to the value of group net credibility. In general, the greater the value of the group net credibility of a project, the better the project is. Simulation experiments suggest that this proposed method is feasible and valid. Extracurricular activities for college students take a very important part of university education, and it models their characters, opens up their minds, adventure spirits, strengthens their social connections, improve their comprehensive quality and their personal positive socialization.
