When Dartmouth suspended its standardized testing requirement for undergraduate applicants in June 2020, it was a pragmatic pause taken by most colleges and universities in response to an unprecedented global pandemic. At the time, we imagined the resulting “test-optional” policy as a short-term practice rather than an informed commentary on the role of testing in our holistic evaluation process. Nearly four years later, having studied the role of testing in our admissions process as well as its value as a predictor of student success at Dartmouth, we are removing the extended pause and reactivating the standardized testing requirement for undergraduate admission, effective with the Class of 2029. For Dartmouth, the evidence supporting our reactivation of a required testing policy is clear. Our bottom line is simple: we believe a standardized testing requirement will improve—not detract from—our ability to bring the most promising and diverse students to our campus.
