The approach of the ERRC involves, in particular, strategic litigation, international advocacy, research and policy development, human rights focused news production, and the training of Romani activists.

[3] Over the next ten years the organisation created over 580 publications, lodged 500 cases in a variety of European countries and trained over one thousand Roma activists.

The ERRC has also launched strategic litigation in the United Kingdom with a notable case being the 2004 R (European Roma Rights Centre) v Immigration Officer at Prague Airport contested in the House of Lords.

The organisation creates its reports using a wide range of methods including work with a broad network of lawyers, journalists, research partners, monitoring bodies and relevant subject specialists.

The ERRC has influenced the European Union enlargement by pressuring candidate countries to comply with the Copenhagen criteria and ensuring that the Roma situation is a priority issue.

After a ten-year-hiatus, the Summer School was revived in 2022 in Budapest[23] and continues to accept applications from Roma, Sinti, and Travellers from around Europe every July.
