Bucknell University welcomed Alpha Delta Pi to campus in fall 2008. First-Year students are not allowed to join Greek groups, so the sororities spent much of spring 2009 marketing on campus about the sorority's fall arrival. The colonization plan was designed to take two years to bring the chapter to the average chapter size of other sororities. In fall 2009, 65 women were extended bids and the chapter moved into their space in Hunt Hall along with the other six NPC groups. Their area includes a large suite for meetings and recruitment, as well as dorm rooms for many members. The chapter immediately became involved on campus, participating in Greek Week, Panhellenic Mocktails and Greek Iron Chef. In fall 2010, Theta Iota participated in their first formal recruitment and welcomed 77 new members, exceeding the goal of reaching average size in two years.
