Multicultural Greek & Fraternal Council

Sororities and Fraternities constituting the Multicultural Greek and Fraternal Council (MGFC) were originally affiliated with specific ethnicities or languages. Most of these organizations are now fully integrated as are the rest of Cornell's Greek letter organizations. All MGFC chapters are. Listed with dates of local founding and national conference membership, these are men's and women's organizations that voluntarily coordinate their efforts within the MGFC. As part of MGFC or University self-governance during disciplinary action, chapters may be suspended ("de-recognized") for a time. Unless the suspensions result in long-term closure of the chapter or forfeiture of a building, they should not be removed from this list. Active groups in bold, dormant groups in ''italics''. See the Office of Student Life for current MGFC members. The inter-Greek councils often cooperate on programs and policies, as do individual chapters from among the several Greek councils. Men's * -

Honor, professional, and service societies

These organizations have a similarly long pedigree on the Cornell campus, but are largely non-residential. Members of the social and academic fraternities and sororities may join or be asked to join, as may non-Greek students. Multiple affiliations are allowable. The cut-off line where any campus organization falls within these headings or without is somewhat arbitrary; those formed prior to 1990 are listed under these subheadings in various volumes of the

Honor and recognition societies

Honor societies In the United States, an honor society is a rank organization that recognizes excellence among peers. Numerous societies recognize various fields and circumstances. The Order of the Arrow, for example, is the National Honor Society of the Boy S ...

recognize students who excel academically or as leaders among their peers, often within a specific academic discipline. Many honor societies invite students to become members based on scholastic rank (the top x% of a class) and/or grade point, either overall, or for classes taken within the discipline for which the honor society provides recognition. In cases where academic achievement would not be an appropriate criterion for membership, other standards are usually required for membership (such as completion of a particular ceremony or training program). These societies recognize past achievement. Pledging is not required, and new candidates may be immediately inducted into membership after meeting predetermined academic criteria and paying a one-time membership fee. Because of their purpose of recognition, most honor societies will have much higher academic achievement requirements for membership than professional societies. It is also common for a scholastic honor society to add a criterion relating to the character of the student. Some honor societies are invitation only while others allow unsolicited applications. Finally, membership in an honor society might be considered exclusive, i.e., a member of such an organization cannot join other honor societies representing the same field. Governance varies from faculty-guided to purely student run. Listed by date of local founding with national conference membership, these are co-ed, non-residential, achievement-based organizations that self-select members based on published criteria. :ACHS indicates members of the

Cornell University Residence Plan of 1966

During AY 1948-1949, Cornell University President

formally distanced the University leadership from the increased discrimination which he observed at Cornell since 1910. His speech at the time marked the beginning an effort to end such unlawful practices, a goal to which the University remains committed. Following hearings into discrimination within Cornell's system of private fraternities and sororities, fifteen fraternities liquidated private holdings and entered into the Cornell University Residence Plan of 1966, or CURP'66, an agreement which required all signatories to refrain from unlawful discrimination. The majority of CURP ’66 houses are on the

. The Plan created a system of 'living and learning' by Small Residence. Each Group House was to be maintained by a Priority Group electing its Group Sponsor.

, for instance, sponsored Group House No. IV d/b/a/ The Irving Literary Society, and developed its parcel on Cornell's West Campus. Cornell desired an academic atmosphere in student residence “units” providing appropriate facilities for intellectual and cultural activities and by encouraging student participation in these pursuits.C.U.R.P. ’66 at 1 (Policy Statement). CURP ’66 was not simply the creation of University-owned fraternities and sororities, but a plan to provide a supplement to the University-maintained dormitory complex, the existing Cornell Greek System, off-campus apartments and rooming houses. The vision was to organize “Small Residences” together, regardless of their national or local orientation as fraternities or cooperatives. The University program provided for no discrimination on the basis of race, creed, color or national origin. The issue of gender was addressed in the equal promotion of female, male and gender neutral Group Houses. In 1997, Cornell's president,

, reaffirmed the Board of Trustees' commitment to the Cornell University Residence Plan of 1966. The current CURP ’66 was created from an existing University leasing system dating to the 1881 decision by

to favor fraternities over dormitories. White thought fraternities “’ ouldarouse in the students a feeling of responsibility both for the care of the property and for the reputation of the house . . . ndfastens upon tudents’duties and responsibilities similar to those of men in the active world was among the better solutions of the problems f. . . students in American universities.’” citing Annual Report (June 20, 1883). White’s vision, in turn, develop from the professional analysis of American architect and planner,

as a reform over the barracks-like dormitories used by existing American universities and colleges. Like White, Olmsted felt clubhouses maintained by the students would form part of the educational experience. They were to be modeled on the typical rural household of the era, small country villas thought to avoid the negative aspects of the Industrial revolution. DKE_Cornell_Chapter
