In the context of EPSO’s selection procedures (competitions) a subject matter expert, or SME for short, is someone whose job is to participate in the process of creating certain types of written tests, such as field-related questionnaires.

SMEs are officials from the EU institutions and bodies served by EPSO. They take on this task for a limited period of time, in parallel with their usual work. Officials become SMEs on a voluntary basis, following a dedicated call for interest. They are nominated formally by their organisation of origin and must have a relevant profile in terms of knowledge or expertise in order to participate in the process of test development. They must have no conflict of interest as regards their competition in order to be confirmed as SMEs.

Nominated SMEs are trained by EPSO on test development methodologies before they take up their duties and continue to receive specific support from EPSO throughout their assignment.

Every test development process is analysed by EPSO’s team of psychologists in order to detect any possible bias. EPSO ensures that the process follows the agreed standards for large-scale selection procedures such as the ones organised by EPSO.
