Developed by people with lived experience as part of the National Involvement Partnership (NIP) project, the 4Pi National Standards ensure effective co-production, thus really improving experiences of services and support.

4Pi was the result of an NSUN hosted project, the National Involvement Partnership (NIP). The aim of the three year project was to strengthen and 'hard-wire' involvement in to the planning, delivery and evaluation of the services and support we use for our mental health and wellbeing needs.

This framework established some basic principles to encourage people to think of involvement in terms of principles, purpose, presence, process and impact (4Pi).

The Five Year Forward View for Mental Health describes 4Pi as a framework that ‘…will help ensure services and interventions are accessible and appropriate for people of all backgrounds, ages and experience’ and should support CQC inspection of ‘the quality of co-production in individual care planning, carer involvement and in partnership with communities to develop and improve mental health services.’
