The PSNI was initially legally obliged to operate an affirmative action policy of recruiting 50% of its trainee officers from a Catholic background and 50% from a non-Catholic background, as recommended by the Patten Report, in order to address the under-representation of Catholics that had existed for many decades in policing; in 2001 the RUC was almost 92% Protestant.
Many unionist politicians said the "50:50" policy was unfair, and when the Bill to set up the PSNI was going through Parliament, Minister of State Adam Ingram stated: "Dominic Grieve referred to positive discrimination and we hold our hands up.
Clause 43 refers to discrimination and appointments and there is no point in saying that that is anything other than positive discrimination."
However, the Northern Ireland Human Rights Commission cited international human rights law to show that special measures to secure minority participation were in accordance with human rights standards and did not in law constitute 'discrimination'.

By February 2011, 29.7% of the 7,200 officers were from a Catholic background, but among the 2,500 police staff (non-warranted members), where the 50:50 rule operated only for larger recruitment drives, the proportion of Catholics was just 18%.
The British Government nevertheless proposed to end the 50:50 measure, and provisions for 'lateral entry' of Catholic officers from other police forces, with effect from the end of March 2011.
Following a public consultation the special measures were ended in respect of police officers and police staff in April 2011.

Deloitte conducted recruitment exercises on behalf of the PSNI, and was the dominant firm in the Consensia Partnership which existed from 2001 to 2009.

As of 2017, the PSNI have announced that it will be introducing new schemes to increase the number of Catholics in the force.
The PSNI is focusing on tackling the fear factor of joining the Service as violent dissident Republicans are discouraging Catholics from joining and continue to attack Catholic officers.
