We used the FAIR Data Maturity Model to evaluate the Repository of psychological instruments in Serbian (REPOPSI) at the end of the project titled "TRUST-ification and FAIR-ification of an open repository for research instruments in psychology: REPOPSI's adoption of RDA outputs" (project team members: Aleksandra Lazić, Ljiljana Lazarević, Danka Purić, Iris Žeželj, Obrad Vučkovac).

We evaluated REPOPSI's Findability, Accessibility, Interoperability, and Reusability (i.e. FAIR-ness) using the "FAIR Data Maturity Model: Specification and Guidelines (1.0)" document ( developed by the RDA FAIR Data Maturity Model Working Group. We measured the progress per indicator, on a continuous scale (0 – not applicable; 1 – not being considered yet; 2 – under consideration or in planning phase; 3 – in implementation phase; 4 – fully implemented).

We have previously used this test at the beginning of the project; the report of that self-assessment test, from December 2022, is available at Comparing the start- and end-project tests, we evaluated the progress we made.

This record contains the checklist (XSLX and CSV) and the report (PDF), which describes the reasoning behind the determined maturity level of each indicator as well as the visualization of the evaluation results (radar charts).


This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 101017536 and is supported by the EOSC Future ( through the RDA ( Open Call mechanism (, based on evaluations of external, independent experts.
