Teaching doesn't make you ineligible for a reality show, but being on a reality show might make you be ineligible to teach - especially very young kids, and extra-special-especially at a Catholic school.
Think of it this way - you are a staunch Catholic and hold marriage in high regard, and you have a 1st grader. You find out your kid's teacher made a mockery of marriage by pretending to go through one for money, and humiliated her parents in the process. Do you yank your kid out of that school? Do you complain to the principal? Dang right you do.
