GradesFirst is a web-based student support system that is used throughout SJSU by colleges, student success centers, and the library. Students enter their IDs into GradesFirst when they attend instruction sessions at the library or have one-on-one sessions with librarians. In the classrooms, there are card scanners attached to the instructors' computers and students scan their Tower cards or key in their ID numbers as they enter. Aggregate data gathered from GradesFirst is used to assess the impact of library instruction and research support on student retention and graduation rates.
