School prefect

A school prefect is a pupil who has been given certain responsibilities in the school, similar to the responsibilities given to a safety patrol members.

United Kingdom

In some British, Irish and Commonwealth schools, prefects, usually students in fifth to seventh years, have considerable power. They were once allowed to administer school corporal punishment in some schools. They usually answer to a senior prefect known as the Head of School, Head Prefect, or Head Boy or Head Girl or Senior Prefect. Larger schools may have a hierarchical structure with a team of prefects, a team of senior prefects, and a Head Boy and Girl. The Head Prefect may also be the School Captain if that is an appointed position in the school. Today, prefect roles in the U.K. are largely perfunctory and are mostly used to reward the better students in the year groups that qualify for prefect roles. Duties tend to be limited to door monitoring during break and representing the school at various extra-curricular events.
The terms for two Senior Prefects, Head Boy and Head Girl, are commonly used in the British education system as well as in schools throughout some Commonwealth countries, e.g. Nigeria and South Africa. Some schools use alternative, gender-neutral titles such as school captain, head pupil/student, head of school, or they adopt the American title of student body president. They are students who carry leadership roles and are responsible for representing the school's entire student body. Although mostly out of use, in some schools, especially when there is only one of them, they are referred to The Senior Prefect. They are normally the most senior prefects in the school.
Head boys and head girls are usually responsible for representing the school at events, and will make public speeches. They also serve as a role model for students, and may share pupils' ideas with the school's leadership. They may also be expected to lead fellow prefects in their duties. In most cases, a deputy head boy and girl will be appointed to assist and deputise the head boy and girl. They may have to do charity events, speak in assemblies, help out in parents evenings, and open days.

Other countries

In India, Pakistan, Sri Lanka, Singapore and Malaysia, prefects are student leaders in primary and secondary schools, often along the lines of other Commonwealth schools, but with superior powers. The prefect systems in these countries have changed little from when they were under the British, as the present governments have seen them as effective.
In the United States, a hall monitor may be either a student volunteer who is charged with maintaining order in a school's corridors. Students may be selected as hall monitors because they are considered mature and responsible enough, or they may be appointed in rotation. While specific duties vary between establishments, hall monitors typically check hall passes; maintain overall good conduct in the corridors; and ensure that students are punctual in attending classes.
In Hong Kong, the British system is also practised, as it is a former British colony.
In Bangladesh, Prefects are the leaders in Army based educational institutions namely Cadet Colleges.
In Mexico, Prefects is an adult head of a grade of a school, a US equivalent would be a dean.
In Sweden, a prefect is the head of a university department.
In Jesuit and other Catholic schools this title was given formerly to members of the faculty, a prefect of discipline in charge of student attendance, general order and such, and a prefect of studies in charge of academic issues.
