If you are considering a career in teaching, I recommend that you investigate the Alliance for Catholic Education or ACE for short.
ACE may offer you an opportunity to get experience and training to be a teacher.
You would also teach in Catholic schools which need your help.
The website explains how it works – https://ace.nd.edu/apply
I understand that it is not just for Notre Dame students but that students from other schools participate as well. It was started at Notre Dame.
