Sacrament Preparation begins when a child is in 2nd grade. 
In this grade they prepare and receive the sacrament of First Reconciliation. 
When a child is in 3rd grade, they prepare and receive the sacraments of Confirmation and First Eucharist. 
Please note that before a child can receive the sacraments of Confirmation and First Eucharist they must submit a copy of their baptism certificate.
