The development of values research, associated with a growing concern of organizational culture issues, provided a fertile field for studies directed to the application of theory to practice. In this scenario, the concept of fit P-O arises in order to obtain more objective information about the congruence between employee and organization, both for diagnosis and proposition of solutions. With a representative sample of a Brazilian public organization (n = 457), the Congruence Index (CI) is proposed, based on vector calculations, which considers both the difference and the intensity of the values profiles. The various methods of calculating congruence performed have shown that the results can be complex and of difficult significance. The presented model is more suitable to a global measure of fit, considering spatial theoretical models. The organization studied had CI = 16%, which is considered a low value of congruence.
