So far, only the other colleges at Columbia University are permanently test optional. Barnard has only extended the policy through Spring 2025 transfers. By then they will have 5 years of experience of reviewing applications that might not include ACT/SAT stats, as well as some insight if there was any meaningful difference of those students’ experiences. They also will realize their admission rate having been pushed into the single digits during those years.
So there are good reasons one could speculate that they might choose to align with the rest of the university - but, if so, a decision and announcement might not come until the spring (as in the past).
