In the context of a sports or arts academy, lots of students are children or teens, so they need a responsible older person who can be reached in an emergency. It could be the student's parent, aunt, uncle, cousin, neighbor, or another person responsible for that student, family or not.
In Spanish, that word is "acudiente": someone to reach out to ("acudir"). What would be the correct word in English? I can't find a correct translation.
I'm trying to find a single word. If there's not a single one, I could go with emergency contact.
