My guess is you are asking about the Rite of Election? The bishop calls you and the other catechumens (the meaning of the word election is calling) to come into the Church. This is sometimes in the context of a Mass, or as part of Vespers, and the timing may vary but the elements should be the same. You are welcomed personally by the bishop, and if there are not too many people you may be able to shake his hand, you will say your name, or your name may be called out by your catechist or pastor. You will come forward to sign your name in the Book of the Elect. If you signed the book previously in your parish, your pastor or director will present the book to the bishop for his signature.
During the course of the rite there will be special blessings for you and your godparents, and they will be asked to attest their intention of doing everything to support you and accompany you in your journey toward Easter, and attest that you are ready to proceed through the rites and period of Lent–purification and enlightenment. you will not yet of course receive communion during Mass, if there is one.
Your catechist or director should explain all this in your class, including the responsibilities of godparents or sponsors–this is the time the role of the sponsor ends, and the godparents step forward to be with you during Lent, Easter and afterward.
The rite of election is for the unbaptized.
Those who were baptized but will be coming into full communion with the Catholic Church are Called to Continuing Conversion. Their sponsors attest to their intention, but there is no book to sign.
