  • The results of the computer-based MCQ tests are eliminatory and will not be taken into account in your final overall marks.
  • However, you must reach the minimum pass mark in all tests and get one of the highest scores in order to move on to the next stage of the competition.


EPSO will check the data provided by each candidate via their online application against the eligibility requirements of this competition. Remember that you can fill out your application in any of the 24 Official EU languages - except for the Talent Screener, which needs to be completed in your chosen Langauge 2 (English or French). 

If the computer-based multiple-choice reasoning tests take place at the beginning of the selection process, eligibility will be checked in descending order of the overall marks obtained during this exam until the number of eligible candidates reaches a certain threshold defined before the tests take place.


You MUST complete your Talent Screener in Language 2 - English OR French.

The selection board assigns a weighting to each selection criterion and based on the information provided in the Talent Screener each candidate will receive a score. Only those candidates with the highest overall marks will go through to the next stage. Therefore, you should include all relevant information in your Talent Screener answers, even if you have already mentioned it in other sections of your application form. The questions are based on the selection criteria included in this notice - see ANNEX II for the list of criteria.

Getting this part wrong can easily jeopardise your chances of moving through to the next stage of the selection process - which you don't want to risk. To better understand how the EPSO Talent Screener works it is advised that you view this webinar recording - Everything You Need To Know About EPSO's Talent Screener.

Those who scored the highest marks in the Talent Screener will be invited to the Assessment Centre. A maximum of 3 times the number of successful candidates sought via this competition will be invited to this phase.

You will be invited to attend an Assessment Centre (online or in-person) over one or several days and will need to be completed in your chosen Language 2. (Further details and instructions will be included in your invitation letter.)

7 general competencies, as well as field-related competencies required for the role, will be tested through 3 tests:​

  1. Case Study
  2. Situational Competency-Based Interview (SCBI)
  3. Field-Related Interview

Each general competency will be awarded a mark out of 10, with a total pass mark required of 35/70. 

In addition to this, the Field-Related Interview will require a minimum pass mark of 50/100.


After checking candidates’ supporting documents, the selection board will draw up a Reserve List of eligible candidates who obtained the highest overall score, until the number of successful candidates sought is reached.
