The aim of the Postulancy is to initiate the candidates into the lifestyle and work of the Congregation, to examine their aptitudes and motivations, and to prepare them for the novitiate (Book of Life, 59). This stage of initial formation usually lasts for one year.

The community of the Sisters of St. Paul of Chartres officially welcomed new postulant Maria Mikaela on January 25, 2022, Feast of the Conversion of St. Paul.
