Peace and Community Action (PCA) works in the areas of conflict transformation, non-violent approaches to conflict, and capacity-building. PCA focuses their programmes on community workers, government officials, youth groups, and people who have been most affected by conflict in Sri Lanka. Thousands of people have been reached through PCA training programmes.

The organisation has implemented a project in Ampara - 'Psychosocial Support Team (PST)' - with former child soldiers and other children who face psychological imbalances after being the direct victims of war.  A project called 'Together for Peace' is another notable achievement of PCA. They were able to connect three major communities in Sri Lanka through youth groups, creating paths to through which PCA can work towards ethnic harmony in Sri Lanka.

PCA has found that through listening to the participants of their programmes, they are able to create more sustainable projects.  This has led them to encouraging participants to design how projects are implemented.
