There are various types of vice-principal:
The person who oversees the school inventory (things they have, things they need, what to buy, when to buy, etc.)
The person who oversees curriculum (setting curriculum for next academic year, evaluating the current curriculum, etc.)
The person who oversees the student activity (which student goes to what competition, which student earn/deserve scholarship, school clubs, etc.)
The person who oversees communication with the public and other schools
How do you call these vice-principals in English: inventory vice-principal, curriculum vice-principal? Is that how they are called, or is there a special term for them?
