International Centre for Prison Studies

A partner of the University of Essex


The International Centre for Prison Studies assists governments and other relevant agencies to develop appropriate policies on prisons and the use of imprisonment. ICPS has an academic partnership with the University of Essex.

The Centre makes the results of its academic research and projects widely available to groups and individuals, both nationally and internationally. These include policy makers, practitioners and administrators, the media and the general public. Such dissemination will help to increase an understanding of the purpose of prison and what can be expected of it.

It carries out work on a project or consultancy basis for international agencies, governmental and non-governmental organisations.
