Twice a year the European Commission takes on around 1,000 trainees for a paid, five-month traineeship. The programme is officially the Blue Book Traineeship programme, and it is the best-known way to spend time inside the EU institutions before — or instead of — an EPSO competition. It is also easy to misjudge: it is not a job, it has an eligibility rule that quietly excludes many of the people most interested in it, and the grant depends on where you are placed. What follows is drawn from the programme’s own pages, read on 16 September 2026.
The two sessions at a glance
| Session | Applications | Pre-selection | Selection | Traineeship |
|---|---|---|---|---|
| October 2026 | 16 March – 7 April 2026 | April – May | June – July | 1 October 2026 – 28 February 2027 |
| March 2027 | 22 July – 4 September 2026 | September – October | November – December | 1 March – 31 July 2027 |
Both application windows opened and closed at 10:00 Brussels time. The rhythm is the useful part: you apply roughly six months before you would start, and the months in between are spent waiting to be chosen.
Three kinds of traineeship, one application
The programme has three strands: an administrative traineeship for university graduates, an administrative traineeship for vocational education and training (VET) graduates, and a translation traineeship, in which trainees translate into their native language from at least two other official EU languages.
You get one application per session. If you submit more than one for the same strand, only the first counts; if you apply to more than one strand in the same session, all your applications are rejected. Pick the strand before you start the form. The rest of this article follows the administrative traineeship for university graduates, the one most readers of this site will want.
Who can apply
| Requirement | What the programme asks for |
|---|---|
| Degree | A full higher-education degree at EQF level 6 or higher, of at least 180 ECTS credits, obtained before the application deadline |
| Languages (EU nationals) | English, French or German at C1 or C2, and another official EU language at B2 or above (native counts in both cases) |
| Languages (non-EU nationals) | English, French or German at C1 or above |
| Nationality | A Member State, or a candidate country with a pre-accession strategy (a limited number of places) |
| Age | At least 18 on the day the traineeship starts |
| Previous EU experience | No more than 6 weeks (42 calendar days) in any EU institution, body or agency |
| Proof | Documents for every qualification and every period of experience you declare, uploaded as one single PDF |
The six-week rule is the one that catches people
Anyone with prior or ongoing professional experience of more than six weeks in any European institution, body or agency is excluded. The programme spells out how wide that is: every institution, body and agency, their representations and delegations, the offices of Members of the European Parliament and the courts — whatever the type of contract.
The practical consequence is about order, not eligibility. The people most drawn to a Blue Book traineeship are often the same people applying for agency contracts, parliamentary assistant posts and other short EU jobs. Take one of those for two months first, and the traineeship is closed to you for good. If you want both, the traineeship has to come first.
How you are chosen: two stages, two different judges
Stage one is pre-selection, run by the Commission. Applications are assessed on these criteria, in this order of importance: education, language knowledge, work experience, international profile, and a rare field of study. EU citizens are assessed within national quotas; non-EU nationals are grouped separately. A pre-selection committee then checks your uploaded documents against what you declared. The programme says the process usually takes four to eight weeks after the deadline.
Two details matter here. Your application is judged on what you can prove: a language level or a job with no document behind it does not help you. And after you submit, no additional documents or corrections are accepted, so the single PDF is effectively final the moment you press the button.
Stage two is selection, run by the services themselves. Candidates who pass pre-selection enter the Virtual Blue Book, the pool that Commission departments and the other participating bodies recruit from. From there you can apply for up to three traineeship positions, and the recruiting service may interview you. When a service picks you, the Traineeships Office issues a placement offer, which you accept or refuse.
What it pays
Trainees receive a monthly grant adjusted to the cost of living in the place of assignment. The programme’s indicative figures for the March 2027 session include:
| Place of assignment | Monthly grant | Extra allowance |
|---|---|---|
| Belgium | €1,572 | Meal and public transport: 5% of the grant |
| Luxembourg | €1,572 | Accommodation: 20% of the grant |
| France | €1,814 | Meal and public transport: 5% |
| Germany | €1,638 | Meal and public transport: 5% |
| Italy | €1,390 | Meal and public transport: 5% |
| Spain | €1,471 | Meal and public transport: 5% |
On top of the grant, and subject to budget, trainees may receive a general travel allowance of €275. Trainees with a recognised disability can receive a supplement of up to 50% of the grant. Health insurance is provided for the traineeship.
Set that against the one cost the Commission does not cover: accommodation. The programme’s own FAQ tells trainees to expect €700–€1,000 a month for housing. In Brussels, where most placements are, that is a large share of the grant — worth planning for before you accept an offer rather than after.
Where trainees work, and how
Most placements are in Brussels, with others in Luxembourg and elsewhere in the EU. Trainees are placed in Commission departments, its executive agencies and Commissioners’ Cabinets, and in a number of other bodies that take part in the programme, including the European External Action Service and agencies such as Frontex and the European Environment Agency. The working week is the Commission’s: 40 hours. Telework away from the place of assignment is limited to five days over the whole five months, so this is an in-person traineeship.
What the traineeship is — and is not
It is five months of practical experience through direct involvement in the work of a Commission service or participating body, in a multicultural and multilingual setting — which is how the programme itself describes it. For anyone considering an EU career, it is a close look at how the administration actually operates.
It is not a recruitment route. Permanent posts as an official are still filled through EPSO open competitions, and temporary and contract posts through their own selections, which our guide to working for the EU without a competition covers. If a career in the institutions is the goal, the traineeship and the competition are complements: one shows you the job, the other is how you get it.
The competition is still the way in
EPSO competitions open with verbal, numerical and abstract reasoning, and they are scored before anything else. Five months in Brussels is a good time to start practising them.

When can I apply for the Blue Book traineeship?
Applications open twice a year, about six months before each session starts. Applications for the March 2027 session ran from 22 July to 4 September 2026 and are now closed. The window for the October 2027 session has not been published yet; the window for the October 2026 session ran from 16 March to 7 April 2026. Check the programme's calendar page early in the year.
How much does a Blue Book trainee earn?
The monthly grant depends on the place of assignment. For the March 2027 session the programme's indicative figure for Belgium and Luxembourg is €1,572 a month, with a meal and public transport allowance of 5% of the grant in Belgium or an accommodation allowance of 20% in Luxembourg. A general travel allowance of €275 may be paid, subject to budget. Accommodation is not covered, and the programme advises budgeting €700–€1,000 a month for it.
Can I apply if I have already worked for an EU institution?
Only if that experience totals no more than six weeks (42 calendar days). Anyone with prior or ongoing professional experience longer than that in any EU institution, body or agency — including delegations, the offices of Members of the European Parliament and the courts, and whatever the type of contract — is excluded.
What languages do I need?
For the administrative traineeship for university graduates, EU nationals need English, French or German at C1 or C2 level and another official EU language at B2 or above. Non-EU nationals need English, French or German at C1 or above. Every level you declare must be backed by a document in your application.
Does being pre-selected mean I have a traineeship?
No. Pre-selection puts you in the Virtual Blue Book, the pool that Commission services recruit from. You can then apply for up to three positions, and services may interview you. There are around three times more candidates in the Virtual Blue Book than places, and an application is valid for one session only — but you can apply again in later sessions.
