Confirmation normally occurs after faith formation and preparation in high school.
Church member will enroll in faith formation for classes during September-May. 

Confirmation or Chrismation is the second sacrament of Christian initiation. It is called Confirmation because it confirms and strengthens baptismal grace." It is conferred by "the anointing with Sacred Chrism (oil mixed with balsam and consecrated by the bishop), which is done by the laying on of the hand of the minister who pronounces the sacramental words proper to the rite." These words, in both their Western and Eastern variants, refer to a gift of the Holy Spirit that marks the recipient as with a seal. Through the sacrament the grace given in baptism is "strengthened and deepened." Like baptism, confirmation may be received only once, and the recipient must be in a state of grace (meaning free from any known unconfessed mortal sin) in order to receive its effects. The "originating" minister of the sacrament is a validly consecrated bishop

CONFIRMATION REQUIRMENTS AND EXPECTATIONS

Confirmation catechsis is a two-year process.
Confirmands must have a sponsor.
A sponsor or sponsors must meet all of the following criteria, which are established by universal Church law and which do not vary from place to place. Sponsors must:
(a)Be Catholic
)b) Have been baptized, confirmed and have received Communion
(c) Be 16 or older (d) Must be living a life consistent with their baptismal vows.
If a sponsor is married, their marriage must be recognized by the Church. A potential sponsor cannot be cohabiting with a partner outside side of marriage.  A practicing Catholic also includes being registered in a Catholic parish and participating in parish life (attending Mass every weekend, contributing to the life of the parish through stewardship of time, talent and treasure, attending parish functions and engaged in ongoing faith formation such as adult faith classes). If a potential sponsor is not a member of the parish where the confirmation is to take place, he or she must obtain a letter or certificate from their own parish pastor which affirms that they meet the above requirements.
The celebration of any sacrament like Confirmation is not a private act. It is a public official liturgy of the Church that seals someone into full membership in the Catholic Church.  Therefore, the  Church has the duty and obligation to require reasonable criteria for being a sponsor. The role of a sponsor is a role of service done in the name of the Church, and the person who is a sponsor should be capable of performing that service
Choosing a confirmation saint name is an essential part of Confirmation and it is an acknowledgement that the Holy Spirit will change you through the grace of this Sacrament. We see in Scripture that Jesus changed the name of some of his disciples to signify that their role had been changed.   When choosing a saint, you should choose someone who exemplifies a quality that you wish to have, somebody whose life you want to emulate, or somebody you have something in common with. You should also be asking for the prayers and intercession of the saint that you choose.  .
