ERME – the European Society for Research in Mathematics Education – was established in 1997 with the aim to promote communication, cooperation and collaboration in mathematics education research in Europe.
ERME became a regional affiliate organization of ICMI in 2010.

The main event organized by ERME is the biannual congress, CERME, usually held in February every odd numbered year.
In between CERMEs, smaller conferences – ERME Topic Conferences – are held.

ERME has its own community for early-career researchers, YERME (Young European Researchers in Mathematics Education). YERME organizes a YERME Day in connection to the CERME congresses, and a summer school – YESS – in years between the CERMEs, as well as a range of online activities.

ERME is led by a board with regional representatives and including two YERME representatives.
The society aims to enable communication of information to enhance the visibility and availability of European research on mathematics education (in Europe and all over the world).
