Impact of academic libraries on grade point average (GPA): a review

The purpose of this paper is to examine the literature to determine how academic librarians are measuring their libraries' institutional level impact on student success as measured by grade point average, a metric commonly used in American education. This paper highlights a range of methods, outcomes and challenges in an initial scoping study.

The methodology centered on a literature review of measuring the impact of academic libraries on student success as quantified by grade point average (GPA) from 2010 to present. Searches in ProQuest, EBSCO and Google Scholar were used to identify the relevant literature. Keywords searched in databases included various combinations of academic impact, student success, learning outcomes, library and higher education.

The analysis of 15 papers shows that academic librarians have demonstrated a small, nonnegligible positive correlation of library usage on GPA. The results of studies have highlighted that correlation does not prove the cause. Concerns and limitations of studies included using the GPA as a measurement of student success, differences between GPAs in subject areas, timeframes used, sample size collected, student privacy and the meanings of the results.

This study is limited to articles published in English measuring student success as quantified by GPA and focuses heavily on American sources.

The research can guide librarians through known challenges and highlight successful designs and study methods used by other academic librarians to measure the impact of the library on student success.
