in this diocese, synod legislation enacted in 2006 revised particular canon law for the diocese, and set the age for first communion at 3rd grade or age 8. That is the bishop’s perogative, because like the age for confirmation, the age for baptized Catholic youth is anywhere over the age of reason, from about 7 to majority, 18, and it is left for individual bishops to set the age for their diocese. Actually several parishes had already been doing this and the reason cited was that the majority of 2nd graders were “not ready” for first communion.

the catechesis for sacramental preparation is also specified, and is part of the guide published by the Office of Catechetics, as an appendix to the synod legislation.
It calls for one year of initial formation, followed by two years of sacramental preparation, with first confession celebrated in the second year, and first communion during the third year. The actual timing within the year is left to the parishes, but it is expected at least 6 months will elapse between the two sacraments, and the state reason for that is pedagogical, that candidates and families will distinguish between the two sacraments. The content of sacramental catechsis, and of required parent-sponsor meetings was also codified.
Since the synod document did not specifically address the issue of RCIA for unbaptized children and the age for sacraments, it was discussed in a follow-up memo. Confirmation age remained at age 16 or 10th grade, and requirements for confirmation catechesis were also set forth in subsequent addenda.
the age for first communion in your diocese is whatever the bishop says it is. if your parish is out of step with diocesan policy, consult the chancery, bishop’s office, vicar general, priest in charge of liturgy and sacraments or office of catechesis for clarification.
