In Romania, distinct proms are held each year in high schools and college for both the graduating students as well as the newly enrolled ones. They are called graduation balls and freshmen ("boboci", meaning "hatchlings" in Romanian) balls, respectively. They are usually not black tie (informal). The venue is chosen by the teaching staff and can be any place, including the school gym or auditorium, a club, or a restaurant. It is common to charge students an admission tax in order to offset the cost. One or more bands or singers are usually hired to provide entertainment. Often the event is sponsored by local businesses. Access is usually controlled and limited to students of that particular high school or university, but exceptions can be made for relatives and it is not uncommon for students from other institutions to try to crash a particular prom. Freshmen proms usually include a popularity contest of some sort, which designates 3 girls and 3 boys as places I, II and III "most popular" as chosen by student vote; the candidates have to undergo various entertaining challenges, which usually include pair dancing. Generally speaking, freshmen proms are the more popular, with college freshmen proms often being publicized as club events and promoted by radio stations, who take the opportunity to introduce bands and singers. Whereas graduation proms are more subdued and often not a public or even a school-wide event, many graduating classes choosing to restrict attendance just to the actual graduates and their teachers.
