Permanent officials
EPSO competitions produce reserve lists for EU institutions. Graduate AD5 competitions require no previous professional experience; specialist competitions have different requirements.

The European Commission assessment process, explained

What to expect in the European Commission assessment
No reviewed source establishes one game-based assessment shared by all European Commission applicants. Identify the named test in your invitation before selecting practice.
Good to know: Game practice is not a substitute for competition-specific preparation. EPSO does not endorse external training services or publications.
Which European Commission roles and programs does this guide cover?
A useful preparation plan begins with the exact opportunity. Copy its reference into your notes and separate mandatory requirements from desirable experience. This prevents time being spent on an assessment that belongs to another route.
This guide distinguishes official process information from suggested exercises. The exercises help you organize practice; they are not leaked questions, predictions of your interview or an official EPSO preparation product.
Contract and temporary staff
The Commission also recruits non-permanent staff. Recruiting services use CAST to find and shortlist contract-agent profiles matching their vacancies.

Blue Book traineeships
Initial assessment considers education, language skills and other experience. Supporting documents are checked before successful applicants enter the Virtual Blue Book.

What happens in the European Commission hiring process?
Permanent competition and recruitment
EPSO selection and an institution’s subsequent recruitment are separate steps.
- 1Read the Notice of Competition and apply through the specified candidate portal.
- 2Complete the competition tests and eligibility checks.
- 3Successful candidates enter a reserve list; institutions can then shortlist and interview for vacancies. Inclusion does not guarantee employment.

Blue Book ADMIN selection
The university-graduate administrative traineeship has its own application rounds.
- 1Candidates in the Virtual Blue Book may apply for up to three positions, one in each round.
- 2Prepare a general motivation statement and a separate PDF cover letter for each position.
- 3Recruiting units may hold an informal interview. Only the official placement offer confirms selection.

When is the European Commission assessment?
Maintain separate reminders for application closure, documents, testing and decisions. Copy times and time zones exactly; a programme start date is not an application deadline.

|---|---|---|---|
| Permanent competitions | Check the individual competition notice | Follow the testing invitation | Official source The competition notice and its webpage are the essential references for the procedure. Do not transfer dates from another competition. Source: Permanent staff selection |
| Blue Book sessions | Check the current session calendar | Selection follows preselection | Official source The programme describes two application periods each year, followed by document verification and selection for specific placements. Preselection alone does not secure a traineeship. Source: Blue Book process overview |
How to prepare for the European Commission assessment process
Build a short plan around your weakest relevant skill. After each practice session, record the error, its cause and one change to try next time. Improvement should be visible in your reasoning and explanations, not simply in the number of questions completed.
1. Audit your evidence
Create a checklist linking every eligibility requirement to a document or example. Verify dates, qualification names and language descriptions against your submitted application. If a statement needs explanation, draft that explanation now. Keep the original document and a clearly named copy together so that later requests are easier to answer accurately.
2. Review reasoning mistakes by type
For numerical practice, distinguish calculation errors from misreading the question or chart. For verbal questions, mark the sentence supporting your answer and notice when an option requires an assumption. For abstract problems, describe the rule in words before choosing. Repeat a difficult question untimed until you can explain the method, then work on pace.
3. Practice writing for a real reader
Choose a short public policy document and write a concise briefing for a reader unfamiliar with it. State the issue, summarize the evidence and identify a decision or implication. Revise once for structure and once for unnecessary detail. Keep your own opinions separate from the document’s claims and avoid introducing unsupported facts.
4. Study with a question in mind
When reviewing EU material, ask which institution acts, what problem the procedure addresses and how the decision moves forward. Draw a simple sequence from memory, then check it against the text. This creates an active reading exercise and reveals gaps more clearly than repeatedly highlighting entire paragraphs.
5. Make motivation specific
Connect the position’s work to something you have actually studied or done. Explain the contribution you could make and the capability you want to develop. Replace broad enthusiasm with an example. For a cover letter, remove sentences that could be sent unchanged to an unrelated team and use the space for relevant evidence.
6. Prepare a clear interview example
Select a project involving an uncertain decision or competing priorities. Explain the context briefly, identify your responsibility, describe your action and evaluate the result. Practice a short version and a deeper discussion. Be ready to explain what you would change; thoughtful reflection is more informative than pretending the work had no limitations.
European Commission assessment FAQ
Does every applicant take the AD5 tests?
No. AD5 is a particular graduate competition route. Identify whether your opportunity concerns a permanent competition, contract post, temporary vacancy or traineeship before choosing practice.
Should Blue Book candidates prepare for EPSO reasoning tests?
The reviewed Blue Book guidance describes application assessment and placement selection, rather than the AD5 test sequence. Prioritize the published requirements and any instructions from your recruiting unit.
Can I use the same motivation for every position?
Create a core account of your interests, then make each position-specific letter concrete. Explain how your evidence fits the work instead of simply changing the team name.
Are these official practice materials?
No. Game Assessment Prep is independent. Use official examples to understand the announced format, and follow the rules in your invitation during any live assessment.
