As the first centralised repository for psychological instruments in Serbian, one of the main goals of the project was to prevent duplication of efforts in translating/adapting instruments and to provide a space for local researchers to promote their original instruments.

REPOSI also had the need to promote its data and services to a wider, global research community.
