EPSO received close to 200 such formal complaints, which were investigated carefully by our staff, together with the external contractor. More than half of those complaints were considered legitimate, and those candidates were given the opportunity to retest. It was not possible to find objective criteria to allow any further retesting, despite the mounting pressure from several candidates and other interested parties.

Some suggested retesting all those candidates who wished to do so. This was out of the question, since it would introduce significant biases in the competition’s results. It would also compromise the basic principles and standards of testing
