Indiana University-Purdue University Indianapolis (IUPUI) was one of many universities that adopted a test-optional admissions policy for the Fall 2021 incoming cohort. However, unlike many institutions that went to test-optional admissions out of necessity, the decision made by IUPUI faculty and administration was thoroughly considered, data driven, and received the support of constituencies throughout the university community. Before that decision was made, staff in the IUPUI Office of Undergraduate Admissions collaborated with staff in the Office of Institutional Research and Decision Support to: scrutinize the validity of standardized tests for the purposes of admissions; conduct analyses to understand the broader impacts of test-optional admissions; and communicate findings and plans to relevant stakeholders. The process IUPUI followed could serve as a model for other institutions considering adopting test-optional admissions on a permanent basis.
