begin with the diocese, they probably have approved programs or guidelines of what should be covered.
questions for you:.
age level of your group
beginners, or those being confirmed this year.
have they attended Catholic school, or have they been attending CCD/RE/PSR before this year?
are you responsible for the whole bag, everything they need to know: creed, sacraments and liturgy, moral life, scripture and prayer
OR simply for immediate prep for the sacrament.
what were they supposed to have learned last year?
what was covered?
The St. Joseph Confirmation book from Catholic Book Publishers (be exact in ordering) contains prayers and practices, rite for confirmation, and the basics of what they need, priced under $5 each in bulk
what is the set-up for your program?
classroom? how many? girls and boys mixed or segregated?
large group presentation, with small group processing?i
s it more of a “youth group” or “class”?
what else is going on that will cover some of the material, so you don’t have to: retreats, monthly or periodic gatherings, sponsor+candidate meetings, diocesan programs etc.
start talking to other confirmation catechists in your parish, town or diocese.
if you are totally in charge of designing a program, let us know, we will start from there
