The relationship between the police and communities can be difficult in ethnically divided societies, especially if membership of the police force is largely drawn from one community. This situation pertained in Northern Ireland, which has separate schools for different religious communities. Despite a major reform of the police after the signing of the Good Friday Agreement (1998), the relationship between the police and the Catholic minority remained difficult and, in particular, the police found it difficult to engage with pupils in some Catholic schools. An education initiative, called Shared Education, was launched in 2006 to support the peace process by encouraging collaborative partnership between Protestant and Catholic schools. This paper examines a school partnership in Northern Ireland in which statutory and non-statutory organisations, including the Police Service in Northern Ireland, were involved. The paper examines how the relationship between the police and the schools was enabled by the collaborative partnership: in particular, it allowed the police to provide information and advice to parents on internet safety and cyber-bullying to parents with whom it would otherwise have been very difficult to engage.
