Occasionally every 4-5 years EPSO and EU institutions may announce internal competitions in which only existing Administrator, Assistants and temporary agents (but not contract agents) can take part who are already working in an EU institution.
The goal is to help in the career mobility of those who may be eligible for higher positions or temporary agents who wish to obtain a permanent employment contract. These exams follow the same rules as any other set by EPSO and the Staff Regulations.
