The Centre carries out research at all levels of the education system.  Research is undertaken on behalf of the Department of Education, at the request of other agencies and on the initiative of the ERC itself and its staff.  An assessment service is also provided through, for example, the supply of standardised tests to schools. The ERC also publishes the Irish Journal of Education.

The Centre continues to operate from a purpose-built premises located on the DCU St Patrick’s Campus in Drumcondra in Dublin. Its Test Department is based in nearby Richmond Road.
