List of Phi Sigma Kappa chapters

The complete Chapter and Colony Roll of Phi Sigma Kappa follows this gallery of historic and newer images. Hover over photos for chapter names and captions. Many of the buildings in the historical photos are still owned by Phi Sig fraternity chapters and their alumni today, having been remodeled and expanded, while others have been replaced:
List of Colonies of Phi Sigma Kappa.
Interest groups form Colonies, which in turn become Chapters by earning a Phi Sigma Kappa Charter from the International Headquarters. A charter is a document which conveys from a governing body permission for a local group to operate as a chapter. A PSK Charter also signifies the date and location of the new chapter, and lists its founding members. In the event of a re-colonization, a new group may still refer to the original charter date when citing the age of their chapter, even in a re-colonization.
Expansion Program.
Phi Sigma Kappa supports a vigorous expansion program of two to four new chapters a year. Phi Sigma Kappa's new colonization efforts typically follow one of three methods: 
The Fraternity takes special interest in re-chartering chapters at schools where it previously had a chapter. In such cases, significant funds may be available to support housing or scholarships that have been held in trust, awaiting re-colonization, by alumni of the original chapter.
Interested non-members can start an Interest Group at their school by contacting the Fraternity's HQ directly, or by joining a nearby active Phi Sig chapter. Unlike many national fraternities, Phi Sig allows a limited number of members from local, accredited schools in the area for this purpose.
The Fraternity maintains several full-time staff members dedicated to expansion and the support of interest groups, colonies and new chapters.
Naming Rules & Colony List.
Interest groups are named temporarily after the school. Where the Fraternity has previously had a presence, re-colonizing groups may refer to themselves by their original chapter name, with the word "Colony" appended. Colonies at schools where Phi Sig "has not" had a presence will be awarded a chapter name as their induction ceremony is scheduled.
Where there is lack of progress or low membership, unsuccessful colonies may be "disbanded" before receiving a charter or series name.
The 1985 merger resulted in the following naming compromises:
Colonies, listed below, are grouped first by those soon chartering, then by colonies, and finally by interest groups and planned expansion targets. Groups that have an active presence on campus are bolded.
