The aim of the postulancy is to initiate the candidates into the life-style and work of the Congregation, to examine their aptitudes and motivations, and to prepare them for the novitiate.

During the postulancy which lasts at least six months and at most one year, fundamentals of doctrine help the postulants to deepen their prayer life. Study of the history of the Congregation initiates them into the life of the Sisters of St. Paul of Chartres.
