I graduated in May from a catholic college. I was part of the ceremony, a small part. First our dean of nursing students spoke, then a nun from the place that owns the school, then our class president, then following that was our guest speaker. We as a class voted on who the speaker was going to be, and then requested their presence. She was someone that meant alot to all of us in class as she was the head of a mental health place we did our clinical rotation on. After her speech, we had the blessing of the pins. After that was the actual pinning. Following the pinning we had several speakers from our class. I personally read a poem I wrote devoted to family members lost during the time we were in school I had a screen placed in the church that would scroll names of family members we lost after I read the poem we handed out roses to family members that had an impact on our education, as we handed out roses a class member, who was a guitarist and singer sang a song (again voted on by the class - I grew to like it although it wasn't the one I voted for). After that someone read a prayer, then another poem and then the passing out of the diplomas.
This was a beautiful event, we had many complements, especially since we pulled it together ourselves, a class of 28. We only had funding from the school on rental of the church and the gym associated with the church. Beyond that, a former classmate made 8 cakes, and another classmate made 4 LG punch bowls of punch. We had to pay for the roses ourselves, and our pins. I created the program that was played with the names scrolling. Basically it was alot of work. We had one girl in our class that insisted on EVERY single thing being a VOTE. It got really old, so one day, when she missed class, we as a class just decided a bunch of things without her lol
It was wonderful in my opinion although it was storming outside and the power went out once in the church, we all joked it was some of us that we weren't supposed to be in a church lol.
If you need other ideas I can tell you some of the ideas we had as well, but most of them were used.
Good luck, make it count it's the only one you'll get
