Coming from someone who has been very active in my church’s Confirmation program since I was Confirmed in 99, I think I have some experience here.
First off, this can very much depend on the Archdiocese you come from. I know a lot of the structure from our monthly classes come from our Archdiocese in LA. Whenever I plan a class for the candidates, I can use a small amount of liberty on how I teach but the themes and messages come from the Catechists Guide. In it, it divides our two year program into three parts; Introduction, Formation and Reflection. When we move our candidates between the first two we have a Rite of Entrance ceremony and when when they transition between the next two we have the Rite of Covenant.
The first section on initiation is not especially theological but it is also the shortest one by far. Most of what we do are get to know each other and establish what we are doing. Once the Rite of Entrance happens, we start to hit on the meaning of the Gospels, sin, death, life, miracles, love, exc. I think the section on reflection is self explanatory.
Now remember, this is the way it is out here. (I live in a suburb of LA) Different parishes in my area do it a different way out here but they should be sticking to the guideline. I have no idea what your Cardinal/Archbishop has in your region but I can’t imagine it is too far from this. Just remember that you are going to have two years or so depending on your area to learn. One day is not everything.
