RCIA is the "Rite of Christian Initiation for Adults". Folks who are looking to join the Church go to classes for several months, then, if they were already Baptized in another Christian church, are Confirmed and receive Communion at the Mass on Holy Saturday. If they've never been Baptized, they receive that Sacrament as well as Confirmation and First Communion that night. This way, they've had a nice long time to study the Church and attend Mass with their fellow parishoners.
It might be that your parish doesn't have the formal RCIA program, but it sounds as though you're doing something similar. I'll keep you in my prayers for your completion of the classes and being received into full Communion with the Church.
