EU Knowledge Test 2026: What You Need to Know

The EU Knowledge test is one of the highest-weighted components in the EPSO AD5 2026 competition. Carrying 30% of the preliminary ranking and 25% of the final ranking, it directly determines whether you make the reserve list. Unlike reasoning tests, where improvement plateaus relatively quickly, EU Knowledge rewards sustained, systematic study — every fact you learn is a potential correct answer.

This guide covers what the test involves, the key topics to study, and how to build a structured preparation plan based on the official competition notice (EPSO/AD/427/26).

Test Format: What to Expect

According to the Notice of Competition, the EU Knowledge test has the following specifications:

• Duration: 40 minutes
• Format: Multiple-choice questions (MCQ)
• Minimum score: 15 out of 30
• Language: Taken in your Language 2
• Preliminary ranking weight: 30%
• Final ranking weight: 25%

This is a substantial test — 40 minutes of dense, knowledge-based questions covering the full breadth of EU institutional architecture, legal frameworks, and policy areas. You have approximately 80 seconds per question, which is enough time to read carefully and think — but not enough to research or guess your way through unfamiliar topics. Systematic preparation is not optional; it is essential.

What the EU Knowledge Test Covers

While EPSO does not publish an exhaustive syllabus, the Notice of Competition and historical precedent indicate that EU Knowledge questions span several broad categories. Below is a comprehensive breakdown of what you should know.

1. EU Treaties and Legal Framework

The treaty framework is the foundation of everything the EU does. These treaties are the "constitution" of the European Union, and questions about them appear in virtually every EPSO competition. You should be able to identify and distinguish between:

• Treaty of Rome (1957) — established the European Economic Community (EEC), created the common market, laid the groundwork for the four freedoms
• Single European Act (1986) — set the deadline for completing the single market, introduced qualified majority voting in the Council for single market legislation
• Maastricht Treaty (1992) — established the European Union as we know it, introduced the three-pillar structure (Community, CFSP, JHA), created EU citizenship, set the criteria for Economic and Monetary Union
• Amsterdam Treaty (1997) — incorporated the Schengen acquis into EU law, expanded the co-decision procedure, created the High Representative for CFSP
• Nice Treaty (2001) — reformed institutional structures (voting weights, Commission composition) ahead of the 2004 enlargement wave
• Lisbon Treaty (2007, entered into force 2009) — the current foundation of the EU, abolished the pillar structure, created the permanent European Council President and the High Representative, gave the Charter of Fundamental Rights binding legal force, expanded qualified majority voting, enhanced the European Parliament's powers

Know what each treaty changed, what it introduced, and how the institutional balance shifted over time. Pay special attention to the Lisbon Treaty, as it defines the current institutional framework that EPSO tests against.

2. EU Institutions and Bodies

You must understand the role, composition, and decision-making powers of each institution. EPSO frequently tests your ability to distinguish between institutions that candidates commonly confuse.

• European Commission — proposes legislation (exclusive right of initiative in most areas), guardian of the Treaties, executive body, one Commissioner per Member State, led by the President of the Commission
• European Parliament — co-legislator with the Council under the ordinary legislative procedure, directly elected by EU citizens, currently 720 MEPs, approves the Commission, holds budgetary power jointly with the Council
• Council of the European Union (Council of Ministers) — co-legislator, represents Member State governments at ministerial level, configurations vary by policy area (e.g., ECOFIN, Agriculture), presidency rotates every 6 months
• European Council — sets the EU's overall political direction and priorities, composed of heads of state or government plus its President and the Commission President, does not legislate, meets at least four times a year
• Court of Justice of the European Union (CJEU) — ensures uniform interpretation and application of EU law, includes the Court of Justice and the General Court, handles infringement proceedings, preliminary rulings, and actions for annulment
• European Central Bank (ECB) — manages monetary policy for the eurozone, sets interest rates, independent from political institutions, based in Frankfurt
• Court of Auditors — audits EU finances, publishes annual and special reports, based in Luxembourg, one member per Member State

Also know the advisory bodies: the European Economic and Social Committee (EESC), representing civil society, and the European Committee of the Regions (CoR), representing regional and local authorities. Both must be consulted on legislation in their areas of competence.

3. Legislative and Decision-Making Procedures

Understanding how EU law is made is essential and is a frequent source of EPSO questions:

• Ordinary legislative procedure (OLP) — the standard co-decision process: Commission proposes, Parliament and Council amend and adopt on equal footing, with up to three readings and a conciliation committee if needed
• Special legislative procedures — consultation (Council decides after consulting Parliament) and consent (Parliament must approve but cannot amend)
• Qualified majority voting (QMV) — the standard voting method in the Council: 55% of Member States (at least 15) representing at least 65% of the EU population
• Unanimity — required in sensitive areas: taxation, foreign policy, defence, new member accession, social security coordination
• Types of EU legal acts: Regulations (directly applicable in all Member States), Directives (set objectives but leave implementation to Member States), Decisions (binding on those to whom they are addressed), Recommendations and Opinions (non-binding)
• Delegated and implementing acts — how the Commission supplements or implements legislative acts, with different levels of Council and Parliament oversight

4. EU Policies and Competences

The EU operates across a wide range of policy areas, each with different levels of EU competence. Key ones to study include:

• Single market — the four freedoms: free movement of goods, services, capital, and persons. The cornerstone of European integration.
• Common Agricultural Policy (CAP) — one of the oldest and historically largest EU policies, reformed multiple times, includes direct payments and rural development support
• Cohesion policy — structural and investment funds aimed at reducing regional disparities, the second-largest budget item
• Common Foreign and Security Policy (CFSP) — intergovernmental in nature, decisions generally require unanimity, led by the High Representative
• Area of Freedom, Security and Justice — Schengen area, asylum policy (Common European Asylum System), police and judicial cooperation
• Competition policy — state aid rules, merger control, antitrust enforcement, managed by the Commission's DG Competition
• Trade policy — exclusive EU competence under the Common Commercial Policy, the Commission negotiates trade agreements on behalf of all Member States
• Environmental and climate policy — shared competence, increasingly prominent with the European Green Deal

Understand the distinction between exclusive competences (customs union, competition, monetary policy for eurozone, common commercial policy), shared competences (single market, environment, transport, energy, area of freedom), and supporting competences (culture, education, tourism, civil protection).

5. EU Budget and Financial Framework

The EU budget is a technical but important topic that appears regularly in EPSO tests:

• The Multiannual Financial Framework (MFF) sets spending limits for 7-year periods; the current MFF covers 2021-2027
• NextGenerationEU — the temporary recovery instrument established in response to the COVID-19 pandemic, funded through common EU borrowing for the first time at this scale
• Revenue sources (own resources): customs duties, VAT-based contributions, GNI-based contributions (the largest source), the plastics own resource, and planned new own resources
• The budgetary procedure involves both Parliament and Council, with the Commission proposing the draft budget
• Major expenditure headings include cohesion, agriculture and natural resources, single market/innovation/digital, migration and borders, neighbourhood and the world, and administration

6. Current EU Developments

EPSO tests regularly include questions on recent EU developments. While we cannot predict specific questions, the following topics represent significant recent developments that any well-prepared candidate should know:

• EU AI Act (Regulation 2024/1689) — the first comprehensive AI regulation globally, establishing a risk-based classification of AI systems with obligations ranging from transparency to outright bans on certain AI practices
• European Green Deal — the EU's plan to achieve climate neutrality by 2050, including the Fit for 55 legislative package (reducing net greenhouse gas emissions by at least 55% by 2030), the Carbon Border Adjustment Mechanism (CBAM), and the European Climate Law
• EU enlargement — candidate countries and their status, the Copenhagen criteria (political, economic, and acquis criteria for accession), ongoing accession negotiations
• Digital Services Act (DSA) and Digital Markets Act (DMA) — regulation of online platforms, digital content moderation obligations, and rules for digital "gatekeepers"
• Strategic autonomy — the EU's evolving approach to defence cooperation, energy security, supply chain resilience, and reducing dependencies on third countries
• Recovery and Resilience Facility (RRF) — the centrepiece of NextGenerationEU, providing grants and loans to Member States for reforms and investments

Study Strategy: How to Prepare Systematically

EU Knowledge is the most "learnable" test in the EPSO competition. Here is a structured approach that builds knowledge in layers.

Phase 1: Build the Foundation (Weeks 1-3)

1. Read the basics: Start with the official "How the European Union works" publication from the EU Publications Office. It covers institutions, decision-making, and key policies in accessible language. This is free and available in all EU languages.
2. Study treaties chronologically: Understand what each treaty added or changed. Create a personal timeline noting the key innovations per treaty. This chronological approach helps you remember the logical progression of European integration.
3. Map the institutions: For each institution, write down its composition, presidency/leadership, voting rules, and main powers. Focus on what makes each one unique and how they interact with each other.

Phase 2: Deepen Understanding (Weeks 4-6)

1. Legislative procedures in detail: Walk through the ordinary legislative procedure step by step. Know when QMV applies versus unanimity. Understand the difference between regulations, directives, and decisions — and when each is used.
2. Policy areas and competences: For each major policy area, know whether it is an exclusive, shared, or supporting competence. Understand the key instruments and recent developments in each area.
3. Budget and finance: Learn the MFF structure, main expenditure headings, revenue sources, and the budgetary procedure. Understand NextGenerationEU and its significance.

Phase 3: Current Affairs and Practice (Weeks 7-8+)

1. Follow EU news: Read the European Council conclusions after each summit, follow major Commission proposals, and note new legislation entering into force. Focus on developments that change how the EU works, not routine news.
2. Practice with questions: Test your knowledge regularly using practice questions. Identify gaps and return to the source material for topics you get wrong. Spaced repetition — revisiting topics at increasing intervals — is particularly effective for knowledge retention.
3. Simulate test conditions: Practice under timed conditions (40 minutes for 30 questions) to build the speed and confidence you need on exam day. Getting used to the time pressure reduces anxiety and improves performance.

Common Mistakes to Avoid

• Confusing the Council of the European Union with the European Council — the Council of the EU (ministers) legislates; the European Council (heads of state/government) sets political direction but does not legislate. This is one of the most common errors in EPSO tests.
• Mixing up QMV thresholds — the current double-majority threshold is 55% of Member States representing 65% of the population, as defined by the Lisbon Treaty. Do not confuse this with older rules.
• Overlooking the Lisbon Treaty changes — many study materials still reference the pre-Lisbon pillar structure, which was abolished in 2009. Make sure your study resources reflect the current treaty framework.
• Ignoring recent legislation — EPSO regularly tests knowledge of developments from the past 2-3 years. If you study only historical material, you will miss questions on the AI Act, Green Deal legislation, or recent institutional developments.
• Studying only institutions — policy areas, budget, legislative procedures, and current affairs are equally likely to appear. Balance your preparation across all topic areas.
• Relying on general knowledge — the EU Knowledge test requires specific, precise knowledge. Vague familiarity with EU topics is not enough; you need to know exact names, numbers, and distinctions.

Why EU Knowledge Matters More Than You Think

At 25-30% of your total ranked score, EU Knowledge is not a minor component — it is one of the three pillars that determine your ranking alongside verbal reasoning and digital skills. And unlike verbal reasoning, where marginal gains become harder as your score improves, EU Knowledge rewards straightforward, cumulative study.

Consider this: if two candidates have identical verbal reasoning and digital skills scores, the one with higher EU Knowledge wins the ranking position. In a competition with tens of thousands of applicants for 1,490 spots, even a few additional correct answers can move you hundreds of positions up the ranking.

The candidates who reach the reserve list are the ones who prepare systematically across all test components, not just their strongest areas. EU Knowledge is where disciplined preparation pays off most reliably — it is the test where hard work most directly translates into a higher score.

Start Practising EU Knowledge Questions

Reading is essential, but practice cements your knowledge and reveals gaps you did not know you had. Active recall — testing yourself rather than re-reading — is proven to be the most effective learning method for factual knowledge.

Pass EPSO offers hundreds of EU Knowledge questions covering treaties, institutions, policies, legislative procedures, and current affairs — designed specifically for the EPSO AD5 2026 format. Practise with instant feedback, track your progress across every topic area, and focus your study time on the areas where you need it most.
