The selection process is designed to assess whether or not you have the right qualities to carry out the role competently. Below you will see an outline of how the selection process works.


You can usually apply to become a prison officer online via the website http://www.justice.gov.uk. From this website you can also search for Prison Officer jobs in your preferred area.
