Nevada State College analyzed EZProxy logs to connect student use of electronic resources to academic success. They found moderate correlations between library use and one-term retention, academic standing, semester GPA, and grades on a research assignment. Future work includes understanding the reasons for these relationships and ongoing assessment through strategic campus partnerships. Limitations include not determining the cause of relationships and using an imperfect measure of library use.

5. Diverse Student Population
“By placing a special emphasis on the advancement of a
diverse and largely under-served student population, NSC is
uniquely positioned to improve our state’s economic and civic
prosperity by bringing educational opportunities to those who
historically have been unable to pursue a baccalaureate
degree.The commitment of the entire campus community to
fulfilling this promise and becoming a national model for
closing equity gaps in student performance is a cornerstone
of the 2015-2020 academic strategic plan.”
-Nevada State College, 2015-2020 Academic Strategic Plan
