The purpose of this study was to determine the various values that influence police officers within law enforcement organizations. The value systems (Tribalistic, Egocentric, Conformist, Manipulative, Sociocentric, and Existential) were based on the "Levels of Psychological Existence" developed by Clare W. Graves. A values test instrument was administered to 297 police officers. Specific hypotheses regarding value differences in law enforcement groups were tested. The results were significant in the areas of Existentialism and higher personal education; Sociocentrism and older age, male sex, detective rank group; Manipulation and younger age, male sex, officer rank group; Conformitism and longer police service, female sex, married officers; and, Tribalism and longer police service, female sex, less personal education.
