Alpha Omega Memorial
  1. ^ Chapter formed from Lambda Sigma Phi, established in 1899. It absorbed Lambda Phi in 1924.
  2. ^ Chapter formed from Ah Bing, established in 1902.
  3. ^ Chapter formed from Alpha Delta Sigma, established in 1900.
  4. ^ Chapter formed from the local group J.F.F., established in 1906.
  5. ^ Chapter formed from Delta Sigma, established in 1896. It closed when the college banned Greek letter organizations.
  6. ^ Chapter formed from Delta Sigma, established in 1895. It was one of two chapters that merged into young Alpha Omicron Pi in 1908 (with the Maine chapter).
  7. ^ The fraternity withdrew the chapter's charter from 1969 to 1989 after its members did not participate in rush in protest of "discriminatory rules" of the Tufts Panhellenic Council. Eighteen years after its restoration, the chapter gave a bid to a transgender student in the fall of 2016. The national fraternity delayed its approval of the bid, resulting in half of the chapter's members leaving in October 2016. Although policies were changed to be inclusive, the national executive board withdrew the chapter's charter on December 11, 2017, citing the chapter's "inability to build its membership to sustain a viable AOII membership experience."
  8. ^ Chapter was created from a group whose origin was in Phi Gamma (local), established in February, 1897. This local became the Gamma chapter of Delta Sigma, a regional sorority, in 1902. That regional sorority contributed two of its three chapters to Alpha Omicron Pi in 1908.
