Hall councils and staffing Hall councils At some institutes, each residence hall has its own hall council. Where they exist, such individual councils are usually part of a larger organization called, variously, residence hall association, resident students' association, or junior common room committee which typically provides funds and oversees the individual building council. These student-led organizations are typically connected at a national level by the National Association of College and University Residence Halls (NACURH). Collectively, these hall councils plan social and educational events, and voice student needs to their respective administration. Staffing In the United States, university residence halls are normally staffed by a combination of both students and professional residence life staff. Student staff members, Resident Assistants, or community advisers act as liaisons, counselors, mediators and policy enforcers. The student staff is supervised by a graduate student or a full-time residence life professional, sometimes known as the hall director. Staff members frequently arrange programming activities to help residents learn about social and academic life during their college life. In the United Kingdom, halls often run a similar setup to that in the U.S, although the resident academic responsible for the hall is known by the term of "warden" and may be supported by a team of vice-wardens, sub-wardens or senior-members; forming the SCR (Senior Common Room). These are often students or academic staff at the relevant university/college. Many UK halls also have a JCR (Junior Common Room) committee, usually made up of second year students who stayed in that hall during their first year. The facilities in the hall are often managed by an individual termed the Bursar. Residence Halls may have housekeeping staff to maintain the cleanliness of common rooms including lobbies, corridors, lounges, and bathrooms. Students are normally required to maintain the cleanliness of their own rooms and private or semi-private bathrooms, where offered. Other dormitories Military dormitories At most U.S. military installations, dormitories have replaced barracks. Much new construction includes private bathrooms, but most unaccompanied housing still features bathrooms between pairs of rooms. Traditional communal shower facilities, typically one per floor, are now considered substandard and are being phased out. U.S. military dormitory accommodations are generally intended for two junior enlisted single personnel per room, although in most cases this is
