What scholarships are available to undergraduates, graduate students, and alumnae?

The Diamond Jubilee Scholarships are specifically established to support undergraduate and graduate students as well as alumnae of Alpha Omicron Pi. This scholarship is part of the organization's commitment to educational advancement and providing financial support, reflecting the values of the sisterhood. The Diamond Jubilee Scholarships celebrate the legacy of the fraternity while encouraging continuing education among its members.

In contrast, the Founders' Scholarships primarily target undergraduate members, while Leadership Scholarships focus specifically on promoting leadership among college students. Academic Excellence Scholarships also have a narrower scope aimed mainly at undergraduate students excelling academically. Thus, the breadth of availability for both undergraduates and graduate students, along with alumnae, makes the Diamond Jubilee Scholarships stand out as the correct answer.
