In the United States, Mexico, and Canada, warden is the most common title for an official in charge of a prison or jail.

In some U.S. states including New York, Pennsylvania, New Jersey, Massachusetts, Connecticut, Rhode Island, California, and Hawaii, the post may also be known as a superintendent.

A warden's regular work may involve supervising security, making inspections, carrying out disciplinary procedures, writing reports, managing admissions and liaising with other professional staff who visit the prison, such as medical staff, probation officers, and social workers.

There are three separate prison services covering England and Wales, Scotland, and Northern Ireland.

Prospective governors would need to pass medical, eyesight and fitness tests, and should be a UK citizen or EU national and be prepared to relocate if necessary.

The companies that run private prison establishments each have their own entry requirements and recruitment methods.

In England and Wales graduate vacancies are advertised each year (usually October) in the national press.

This route is only open to those holding degrees, with a preference for candidates with relevant experience in the armed forces or police.
