Phi Sigma Kappa has remained male-only, having itself had little call to change that policy. However, should that call ever come, among fraternities, a workable co-ed solution may be observed, where several national fraternities have adopted co-ed "Society" versions of themselves, as parallel organizations, to accommodate those chapters that choose to become co-educational. An example is the Alpha Delta Phi fraternity and the Alpha Delta Phi Society, the latter of which hosts its co-ed chapters and where both use the fraternity's symbols. Phi Sigma Kappa has never been petitioned for similar formation of a co-ed "branch," thus how it would respond is unknown. However, it "has" expressed strong interest in reopening closed and 'legacy' chapters on its older campuses.
