Competition Phases


Candidates applying to this competition must submit their application online through the EPSO website by 21 November 2023 at 12:00 noon / Brussels time (CEST). The application can be submitted in any official EU language.

Candidates must also upload, through their EPSO accounts, scanned copies of documents that support the declarations made in their applications. This has to be done latest by 10 January 2024 at 12:00 noon / Brussels time (CEST).


All EPSO candidates who submitted and validated their applications by the due date will be invited to sit a series of tests:

a) REASONING TESTS - Language 1

These tests are done in one of the 24 official languages of the EU - but NOT English (or French if you are profile 1). These are multiple choice tests that assess your logical reasoning skills.





Verbal Reasoning

20 questions

35 min


Numerical Reasoning

10 questions

20 min

NR and AR combined passmark: 10/20

Abstract Reasoning

10 questions

10 min

b) FIELD-RELATED MCQ Test - Language 2

IMPORTANT: Only those candidates who reach the passmarks on the CBT will have the results of their MCQ test processed. 

The EPSO field-related MCQ will be specific to the field chosen by candidates, must be taken in your Language 2 and will be organised as follows:





Field-related MCQ


40 min


Candidates need to reach the pass mark, as well as be among those who score the highest overall. Candidates who reach the passmark will be ranked in descending order of the scores obtained. The ranking will be used to determine whether or not candidates will have their case study scored and for the purpose of establishing the reserve lists.


The EPSO Case Study is used to assess written communication skills. The scoring is 0/10 and the passmark is 5/10

The Selection Board will then assess and score the case studies of candidates based on the ranking order determined by candidates' MCQ scores (highest first), until the number of candidates is reached that is not more than 1.5 times the number of places on the Reserve List for each field.


The case study scoring and eligibility check are done in tandem. The Selection Board will determine a candidate's eligibility by comparing the declarations made by the candidate in the application with the supporting documents uploaded by the candidate to their EPSO account. 


Candidates are only eligible for the reserve list if they:

  • reached the relevant pass mark on all the tests
  • has one of the highest scores on the field-related MCQ
  • were found eligible

After checking candidates’ supporting documents and scores, the EPSO Selection Board will draw up the Reserve Lists of eligible candidates for each profile. Once the number of places on the reserve list for each profile has been reached, eligibility of the remaining candidates will not be checked.

The candidates who made it on to the reserve list will be notified directly by EPSO. The reserve lists will then be made available to the relevant recruiting services.
