The postulancy is that stage of initial formation which precedes and prepares for entry into the novitiate. It has its own organization distinct from that of the novitiate (Can 597 & 2). ​

The postulancy offers the candidate the means to continue to mature as a person and to enrich her faith, so that she can discern how authentic her vocation to the university Sisters of Assumption life is. It brings to maturity her decision to enter the novitiate by allowing her to experience for the first time the Congregation, Religious Community and Apostolic life (John 1:46; Vat II Renewal of Religious Life No.4).
