The Office of Institutional Research records consist of the documents and data compiled for national surveys and reports, accreditation, institutional analysis and planning.

The University of San Diego Office of Institutional Research began in 1979 with Sister Maureen Cronin as the Director. The Office oversaw the collection of data used for accreditation, surveys, reports, and institutional planning. Data included enrollment, application statistics, student profiles, faculty profiles, faculty salaries, faculty workload, student/faculty rations, undergraduate majors, student credit hours, retention and attrition rates, graduation rates, degrees awarded, financial aid, tuition and housing data, and national, state, and California trends. This compiled data was used for University reports, analysis, and planning as well as state and national surveys and reporting.

The majority of this collection is open for research. Files containing personally identifiable information for students and faculty are restricted.
