How EPSO assesses language
EPSO does not run a single "language test" the way some national civil services do. Language proficiency is assessed at multiple points in the selection model and varies sharply by competition type. For most generalist competitions there is no standalone written language exam; the reasoning tests are taken in your declared first language and the Assessment Centre exercises are typically in your declared second language, so your language proficiency is observed in context. For linguist competitions — translators, interpreters, lawyer-linguists — there are dedicated profession-specific language exercises that test translation accuracy, interpretation quality, or legal-linguistic precision.
This page covers both: the language regime applied to generalist competitions like the AD5 graduates route, and the specialist tests that linguist competitions add on top. It sits inside the broader EPSO competitions guide.
CEFR levels and what EPSO requires
EPSO uses the Common European Framework of Reference for Languages (CEFR), the same framework as Cambridge English, DELF/DALF, Goethe-Zertifikat, and most European university programmes. Levels run from A1 (beginner) through C2 (mastery).
- Main language: minimum C1 (effective operational proficiency). You can understand a wide range of demanding, longer texts and recognise implicit meaning. You can express ideas fluently and use language flexibly for social, academic and professional purposes.
- Second language: minimum B2 (vantage). You can understand the main ideas of complex text on both concrete and abstract topics and interact with a degree of fluency that makes regular interaction with native speakers possible.
- Specialist competitions may require a third language at B2 or higher; check the notice.
- Linguist competitions typically require C2 in the target language plus thorough knowledge of two other EU languages.
What counts as proof
EPSO is permissive about the form of proof but strict about the substance. Acceptable evidence usually includes:
- A recognised CEFR-aligned certificate (Cambridge, DELF/DALF, Goethe, IELTS, TOEFL with conversion table, TestDaF, etc.).
- A university diploma issued in the language.
- Citizenship of a country where the language is official, plus secondary or tertiary education in that language.
- Documented professional use of the language for a sustained period (less common; the notice specifies).
The competition notice fixes the precise list. Mismatches between what you declare and what you can document are a frequent source of exclusion at the eligibility-check stage. Gather your evidence before you click submit.
Worked example: linguist translation exercise
For linguist competitions EPSO sets a translation task in the candidate's target language pair. Here is a representative item with a step-by-step approach.
Task. Translate the following passage from English (source) into your target language (assume French here for illustration). You have 60 minutes. Translation aids — dictionaries, online resources — are usually permitted in recent cycles for linguist competitions; the notice specifies.
"The Commission's proposal seeks to harmonise minimum corporate-tax rates across the Single Market by 2027. Member States retain discretion to set rates above the floor; below the floor, top-up taxes apply. The proposal is part of the broader OECD Pillar Two framework, to which 138 jurisdictions have so far signed up. Implementation will be monitored by a joint Commission–Council committee, with a first review scheduled for 2030."
Step 1 — read for sense, not for words. Identify the structural backbone: there is a proposal, a timing element, a discretion-and-floor mechanism, an international context, and a monitoring arrangement. Translate the structure first; the lexical choices follow.
Step 2 — handle the institutional terminology. "Single Market" is marché unique (always lowercase in French unless followed by a defined name). "OECD Pillar Two" is Pilier deux de l'OCDE. "Member States" is États membres with capitals. EU institutional French has its own house style; consult the EU's Interinstitutional Style Guide if in doubt.
Step 3 — sample translation.
"La proposition de la Commission vise à harmoniser les taux minimaux d'imposition des sociétés dans le marché unique d'ici 2027. Les États membres conservent la faculté de fixer des taux supérieurs au plancher ; en deçà du plancher, des impôts complémentaires s'appliquent. La proposition s'inscrit dans le cadre plus large du Pilier deux de l'OCDE, auquel 138 juridictions ont adhéré à ce jour. La mise en œuvre sera suivie par un comité conjoint Commission-Conseil, avec un premier réexamen prévu pour 2030."
Step 4 — review for the rubric. EPSO scores translation quality on accuracy (no meaning shifts), fluency (natural target-language prose), terminology (correct institutional and domain terms), and register (matching the formality of the source). Re-read with each axis in mind.
The trap candidates fall into is calque — translating word-for-word, producing something that is technically correct but reads as a translation. EPSO assessors are professional linguists; calque is the first thing they spot. The fix is to draft, then re-read aloud asking "would a native speaker actually phrase it this way?" If the answer is no, rephrase.
Recent format changes (2024–2026)
EPSO modified its language regime several times in the 2010s and 2020s in response to legal challenges over the restriction of second languages to English, French and German. The Court of Justice has at times annulled language regimes that were not adequately justified. Recent notices typically include a justification for the second-language regime applied. For linguist competitions, EPSO has trialled remote-proctored translation tests and updated the permitted aids. Format may evolve further; check the official EU Careers portal for the live notice and any associated guidance documents.
Common mistakes
- Picking a "comfortable" but ineligible second language. If your second language is not English, French or German for a competition that requires those, you will be excluded regardless of fluency.
- Declaring a level you cannot evidence. EPSO checks proofs at eligibility stage. A C1 declaration without a C1-aligned certificate or equivalent is a fast exclusion.
- Underestimating the Assessment Centre language load. Speaking professionally for two hours in your second language is a different challenge from passing a B2 exam. Practise sustained speaking, not isolated grammar.
- Overestimating native-language advantage. Sloppy writing in your first language can fail the case study. C1 is a floor, not a ceiling.
- Ignoring institutional terminology. EU institutional French, German and English have distinct house styles. Read three Commission communications in your second language before the test.
- Calque in translation. Linguist candidates lose marks on calque more than on any other single failure mode.
- Forgetting that the second language is also assessed implicitly in the competency interview. Even when the interview is in your first language, transitioning briefly into your second to clarify a term is sometimes scored.
- Treating language preparation as separate. Use your reasoning-test practice and Assessment Centre rehearsal as language practice. Integrated practice beats isolated language drills for most candidates.
Preparation resources
Official
- EU Careers sample tests — sample exercises for linguist competitions and Assessment Centre activities.
- Interinstitutional Style Guide — the EU's official style guide for institutional writing across all languages.
- Commission strategy documents — read three in each of your declared languages before the test.
Public study material
For CEFR certification, the Cambridge, DELF/DALF, Goethe-Zertifikat and TestDaF official preparation books match the rubric EPSO uses to assess proofs. For institutional language exposure, follow the institutional accounts of the Commission, Parliament and Council on social media in your second language; the daily exposure to formal institutional register adds up over a few months.

Strategy
For generalists, the highest-leverage language preparation is sustained exposure to institutional prose in your declared second language. Read, listen, watch in that language daily for the three months before the Assessment Centre. The objective is not to lift your CEFR level — that is a multi-year project — but to make institutional vocabulary and register reflexive, so you do not stumble in the case study or in the oral presentation. Listening matters: most candidates write in their second language reasonably well but struggle with the comprehension speed required to handle a panel's follow-up questions. Podcasts from EU institutions and quality French/German/English news radio are free, daily, and exactly the right register.
For linguist candidates, the work is different and bigger. Translation accuracy is built through volume and feedback. If you are aiming at a translator competition, translate two pages of EU institutional source material per day for at least three months, with periodic review by a professional. The EU Careers sample translations are useful for calibration but not enough for volume.
For interpreter candidates, the parallel discipline is shadowing — repeating speeches in the source language with a short delay — and consecutive note-taking practice with EU plenary debates as source material. The European Parliament publishes verbatim recordings of plenary sessions in every official EU language; they are an unrivalled free resource for interpreter preparation. Pair them with the official EPSO sample tests to calibrate timing and difficulty against the actual exam.
A practical note for both generalists and linguists: keep a vocabulary log. Every time you encounter a piece of EU institutional terminology you do not know — co-decision, trilogue, comitology, REACH, LIFE, MFF, NDICI — write it down with the equivalent in your other working language. After three months you will have a domain-specific glossary that no commercial preparation course can match, because it is built around the gaps in your own knowledge.
Frequently asked questions
Do EPSO competitions have a separate language test?
It depends on the competition. For most generalist competitions there is no standalone written language test; your language proficiency is evaluated through the reasoning tests (taken in your declared first language) and the Assessment Centre exercises (typically in your second language). Linguist competitions for translators and interpreters have separate, profession-specific language exercises.
What second languages does EPSO accept?
For most generalist competitions the second language must be English, French or German. The notice specifies the regime; some specialist competitions accept other official EU languages. Always check the live notice.
Do I need a language certificate?
EPSO accepts CEFR-aligned certificates, university diplomas in the language, native-speaker status, or evidence of professional use. Specifics vary by competition; the notice fixes the acceptable proofs.
