Eligibility criteria refer to the specific requirements and conditions that candidates must meet in order to participate in  EPSO selection procedures. 
These criteria ensure that only qualified and suitable candidates are considered for the positions and that they meet the necessary standards for working within the EU institutions. 
The eligibility criteria typically include aspects such as nationality, character, education, work experience, language proficiency, and any additional requirements specified in the Notice of Competition for a specific EPSO competition. Meeting these criteria is a prerequisite for being considered in the selection procedure.
