In its work INTER-ACTIE strongly relates to the following principles:

Participation of stakeholders
Participatory approaches to development form the basis for ensuring that projects directly relate to the needs and capacity of organisations and the communities they are working with.

Indigenous expertise
In order to adapt best practices, knowledge an experiences to local circumstances, the utilisation of indigenous expertise is considered to be crucial.

Sustainable solutions
Projects have a clear begin and an end, development however is a continuous process and therefore projects aimed the development of local communities should take into account the possible long term effects of project interventions on those communities and their environment.

Respect and openness
People themselves are central to development of communities and their priorities and choices should be respected, however in order to support decision making processes, all alternative options and opinions should be pointed out.
