Each undergraduate student is levied a Student Activity Fee (SAF). The SGA is given full authorization of how to spend the funds, used to enhance student life. All of the various student organizations are funded by the SGA for programming and services to inform and entertain students. The SGA also acts as a voice for undergraduate students, and there are several committees that attempt to improve the quality of life of Stevens students. The suggestions, grievances, and proposals of all students on campus-wide issues are acted upon through the passing of resolutions and laws to better student life at Stevens Institute of Technology.
