At the conclusion of the pre-novitiate year, the young woman begins a more intensive period of preparation which lasts at least two years. During this time she participates in and is educated through the life, prayer and ministry of the community. It is a time when she deepens her personal relationship with Christ,  gives a concrete response to the call of God and   discovers the spirituality of the Institute,  preparing herself for consecration by the vows. This period of time is referred to as the novitiate. Vows of poverty, obedience, and chastity are taken for a few years at the end of the novitiate.

Preparation for life as an FMM is deepened through participating fully in the life, prayer and ministry of the community. At the end of this time of preparation a young woman makes her final commitment as an FMM. At that time, she receives her first sending from the Superior General, assigning her to mission, which may be to any country in the world where the FMM are present.

Every Franciscan Missionary of Mary continues deepening her living of the special path of the Institute throughout her life. This is done through regular prayer, study and reflection with the sisters of her community. It is also carried out through times of spiritual renewal at particular moments during life.
