Candidates may be disqualified in case they provide false or intentionally inaccurate information, such as their basic qualification, citizenship, diploma or other information. If a candidate does not show up in the test centre, he or she can also be disqualified, similarly to when a candidate fails to submit documents despite being requested to do so by EPSO, or breach the rules of the exam in the test centre or in the Assessment Centre by using unauthorised external help, mobile devices or other.
An appeal may be launched against any disqualification in the normal way, ie. by filing a complaint to the Selection Board and/or to the European Ombudsman.
