EPSO Language Rules and Strategy: Language 1 vs Language 2, 24 Official EU Languages

One of the most significant changes in recent EPSO reforms is the expansion to all 24 official EU languages. Starting in 2024, candidates can now take their entire competition in any combination of the EU's working languages — no longer restricted to English, French, or German for Language 2. This article explains the rules, levels required, and the strategic decisions every candidate must make about language choice.

The Basic Rule: Two Different Languages Required

Every EPSO candidate must demonstrate competence in at least two different official EU languages. You declare these in your application as:

• Language 1 (L1) — typically the language of your reasoning tests (verbal, numerical, abstract)
• Language 2 (L2) — typically the language of your written test and SJT

These must be different. You cannot declare English as both L1 and L2. However, your profile and institution may allow or require specific language combinations — read the competition notice carefully.

The 24 EU Official Languages (Since 2024)

Before 2024, EPSO restricted Language 2 to a small subset (typically English, French, German, sometimes Spanish). This created a bottleneck for candidates from smaller linguistic backgrounds. As of 2024, you can now choose from all official EU languages:

Language Family	Languages (24 total)
Nordic	Danish, Swedish, Finnish
Germanic	German, Dutch, English
Romance	French, Italian, Spanish, Portuguese, Romanian
Slavic	Polish, Czech, Slovak, Slovene, Bulgarian, Croatian
Baltic	Lithuanian, Latvian
Hellenic	Greek
Other	Hungarian, Maltese, Irish

What this means strategically: A candidate from Portugal can now take Language 1 in Portuguese and Language 2 in Portuguese as long as they also declare a second language; a Polish engineer can take their entire exam in Polish without forcing themselves into English or French. This is a game-changer for non-Anglophone candidates.

Required Proficiency Levels (CEFR)

EPSO requires candidates to meet minimum proficiency levels according to the Common European Framework of Reference for Languages (CEFR):

Language	Required Level	CEFR Definition
Language 1	C1	Proficient User — Advanced/Mastery. You can understand long complex texts, express yourself fluently and spontaneously, use language flexibly for social, academic, professional purposes. Near-native fluency.
Language 2	B2	Independent User — Vantage. You can understand main points of complex texts, interact with native speakers with ease and fluency, produce clear detailed texts on complex topics. Solid professional competence.

Important caveat: These levels are self-declared in your application. EPSO does not formally test language proficiency at the competition stage — it trusts your honesty. However, EPSO reserves the right to request language certificates (TOEFL, DELF, DELE, etc.) during the recruitment stage if your language claim is challenged.

How to prove your level: If in doubt, hold official certificates (CEFR-aligned):

• English: TOEFL (90+), IELTS (7.5+), Cambridge CPE
• French: DALF C1/C2, TCF
• Spanish: DELE C1
• German: Goethe-Zertifikat C1, TestDaF
• Other languages: Check official EU framework certification bodies

If you have university degrees or professional experience in a language, that often suffices as proof — no need for a separate certificate.

How Tests Are Distributed Across Languages

In a typical EPSO competition, the language breakdown works as follows:

Computer-Based Tests (CBT) — Reasoning & Written

Reasoning tests (Verbal, Numerical, Abstract): Conducted in Language 1. All 40 reasoning questions appear in your L1.

Written Test (WT, FRWT, EUFTE): Conducted in Language 2. You write your 90-minute response in your L2.

SJT (Situational Judgment Test): If included, usually in Language 2 — though some competitions may vary. Check the competition notice.

Digital Skills Test: If applicable, usually in Language 2 or the language of your role profile.

Interview Stage (DG Recruitment)

The DG typically conducts the interview in Language 1, Language 2, or a third institutional language depending on the role. For some posts (e.g., translator, EU affairs officer), multilingual interviews are common.

Strategic Language Choice: What Language 1 Should Be

Choosing your Language 1 is critical because speed and accuracy in the reasoning tests matter. Verbal and Numerical Reasoning are timed: 35 minutes for 20 verbal questions, 20 minutes for 10 numerical questions. You have roughly 2 minutes per question on average.

Your Language 1 should be the language in which you:

• Read fastest without losing accuracy. You need to extract meaning from a complex policy text in under 2 minutes. This favours your strongest analytical language, not necessarily your native language.
• Do mental arithmetic naturally. For numerical reasoning, you mentally convert percentages, ratios, and currency. The language of calculation should be automatic.
• Reason abstractly without translation. Abstract reasoning has no language per se, but the questions themselves are phrased in your L1. Choose a language where you think logically without mental friction.
• Have substantial professional or academic experience. If you've worked in a field for 5+ years using English or German or French, that's likely your L1 — your brain is already "wired" in that language for professional contexts.

Common mistake: Candidates choose L1 based on native language ("I'm French, so L1 = French"). But if you've lived in Germany for 10 years working in finance, German is actually your faster reasoning language. Be honest about your cognitive strengths, not your passport.

Strategic Language Choice: What Language 2 Should Be

Language 2 is for your Written Test — a 90-minute composition where you demonstrate:

• Clear structure and argumentation
• Professional register and vocabulary
• Syntactic accuracy under pressure
• Domain-specific terminology (for FRWT)

Choose Language 2 based on:

• Writing clarity under pressure. Can you compose a coherent 500-800 word memo or analysis in this language in 90 minutes without major grammatical errors?
• Vocabulary richness and precision. Does this language allow you to express nuance and complexity, or are you restricted to basic phrases?
• Institutional familiarity. Many EU writers use English or French professionally. If you write policy documents or reports in your L2, you already have the register.
• Risk tolerance. Some candidates use their native language as L2 for safety, reasoning "at least I won't make basic mistakes." Others strategically choose a weaker second language if they're very strong in L1, betting that strong reasoning scores will outweigh slightly lower writing scores.

Conservative strategy: L1 = your fastest reasoning language, L2 = your best writing language (often native).

Aggressive strategy: L1 = very strong non-native, L2 = native or near-native, gambling that L1 reasoning scores will be high enough to offset any L2 imperfection.

Special Cases and Constraints

Linguists (Translators, Interpreters, Lawyer-Linguists)

Specialist competitions for linguists have different rules. Lawyer-Linguists, for example, often have constraints like:

• Language 1 must be your native language or a language in which you have native-level written competence.
• You may be required to take tests in multiple languages simultaneously (e.g., a Lawyer-Linguist candidate might be tested in French and German in addition to English).
• Language combinations may be pre-specified by the Court of Justice or institution (e.g., "English-French-German combinations only for the Luxembourg role").

Always check the competition notice; linguist rules are more restrictive than generalist rules.

Institution-Specific Language Requirements

Some institutions or roles have language preferences or requirements:

• European Parliament: May prioritize candidates with working knowledge of multiple official languages for certain roles.
• Court of Justice: Often requires candidates to work across multiple languages; linguists must be native or near-native in at least one.
• Council: Language requirements vary by role (presidency support roles often need EU working languages).
• Commission: Generalist roles (AD5) accept any two of the 24; specialist roles may have language preferences.

Read the Notice of Competition (NoC) carefully for any language-specific instructions in your profile section.

Language Switching Between Competitions

You don't have to use the same Language 1 and Language 2 across multiple competitions. If you pass the AD5 generalist competition with English L1 and French L2, you can later apply for an AD9 specialism with Spanish L1 and Italian L2. However, you still must meet the C1/B2 threshold for each new language pair.

Practical Preparation Strategy by Language Pair

For English L1 + French L2 (or similar major pair)

This is the most common pairing globally. Preparation is straightforward:

• Use English-language reasoning prep materials (dozens available)
• Practice Verbal Reasoning using English policy texts from EUR-Lex or EU institutions
• Practice Numerical Reasoning using EU statistical data
• Prepare your Written Test using French business/policy templates
• Interview prep can focus on English or French depending on role

For Non-Major L1 (Polish, Dutch, Portuguese, etc.) + Major L2

If your L1 is a smaller language but L2 is English or French, you face a resource constraint: few reasoning test prep materials exist in your L1 language. Solutions:

• Use materials in your L1 for familiarity, then practice extensively in a very close language variant (e.g., Czech prep materials if your L1 is Slovak)
• Switch your reasoning study to English, focusing on speed. Do "L1 reading warmups" daily to maintain fluency, then switch to English verbal/numerical practice
• Find EU-language prep communities (forums, Facebook groups) specific to your language — often other candidates from your country have compiled translated materials or study guides

For Both L1 and L2 Non-Major

This is the most challenging scenario: you're using two smaller EU languages with minimal prep resources. Strategy:

• Accept that you'll prepare primarily in English, then do intensive language-switching drills 4 weeks before test day
• Use dictionary and glossary tools heavily; become expert at fast terminology lookup
• Focus on mastering the test formats and content logic (the reasoning is language-neutral; it's the vocabulary and phrasing that's hard)
• Consider whether one of your languages could be replaced with English or French for this competition; revisit in a future attempt if needed

The 2024 Reform Impact: What Changed for You

Before 2024	Since 2024
Language 2 limited to ~5-6 languages (EN, FR, DE, ES, IT, sometimes NL)	Language 2 can be any of 24 official EU languages
Portuguese speaker had to take L2 in English or French (not L1 Portuguese)	Portuguese speaker can now take both L1 and L2 in Portuguese (as long as one is different from L1)
Candidate from Cyprus might be forced into one of 5 major languages	Candidate can now use Greek comfortably
Prep materials heavily concentrated on EN/FR/DE	Growing resource demand for other languages; some scarcity remains

This reform dramatically opened EPSO to non-Anglophone and non-Francophone candidates. If you're from a smaller EU country, your natural language pair is now viable — you don't have to fight the system.

Key Takeaways

• Two languages required: L1 (C1) for reasoning, L2 (B2) for writing and general competence.
• All 24 EU languages allowed since 2024: Choose based on cognitive fit, not policy restrictions.
• L1 strategy: Speed + accuracy in reading and calculation. Often your strongest professional/academic language.
• L2 strategy: Writing clarity under pressure. Often native or near-native for safety.
• Level proof: Self-declared but can be challenged; have certificates ready if questioned.
• Special cases: Linguist and institution-specific rules exist; read the competition notice carefully.
• Non-major languages: Fewer prep materials exist, but communities and strategies exist to overcome this.
• Switching between competitions: You can use different language pairs in different competitions; no lock-in.
