Faith-based colleges and universities in America have historically been described as "church-related." Unfortunately, this classification is too one-dimensional, revealing virtually nothing about how faith-based identity influences the mission, rhetoric, curriculum, or policies of institutions. Although scholars have advanced sophisticated typologies of Protestant and Catholic institutions, we propose that we still need a new means of empirical analysis to determine the degree to which the faith identity of an institution influences important administrative, curricular, and co-curricular decisions. We then apply our Operationalizing Faith Identity Guide (OFIG) to Protestant institutions in the United States to demonstrate the helpfulness of its application.
