The Community Safety Accreditation Scheme (CSAS) and Railway Safety Accreditation Scheme (RSAS) create a framework for public and private bodies to work in partnership with the police, providing an additional uniformed presence in communities and on the rail network to assist in reducing criminality and anti-social behaviour.

After successful company approval employees of that company must apply for accreditation with their local police force. To achieve accreditation an individual must be vetted and approved by the Chief Police Officer of the area they work in, and successfully complete the required training.
