Every year, thousands of candidates try their luck to integrate the European institutions, but few really know how to prepare effectively. EPSO competitions are known for their high level of competitiveness and demand. Without structured preparation and adequate resources, it is easy to feel overwhelmed at the outset.

This is precisely where the European Training Centre comes in, an accompanying mechanism designed to guide candidates towards success, regardless of their previous experience. Whether you're discovering the world of European competitions for the first time or trying to optimize your method of work, this comprehensive guide is for you.

In this article, you will find out how the European Training Centre works, what services are offered, how to choose the formula most suited to your profile and what strategies to adopt to maximize your chances of success. Each step will be clearly explained, with concrete and accessible advice to enable you to move forward with confidence and method.

EPSO: the official selector of the European institutions

Established in 2003, the European Personnel Selection Office (EPSO) is the central interinstitutional body responsible for organising selection procedures for almost all the major institutions of the European Union. It covers the European Parliament, the Council of the EU, the European Commission, the Court of Justice, the European Court of Auditors, the European External Action Service (EEAS) and several other executive bodies and agencies. Understanding the precise role of EPSO is the first necessary step for any candidate starting his reflection on a career in the European institutions.

EPSO selects, but does not recruit. It organizes the tests, publishes the results and places the successful candidates on a reserve list. The institutions themselves then consult this list and recruit according to their actual needs. This distinction is fundamental: being a winner of an EPSO competition does not automatically guarantee a job, but opens an official door to European institutional employers.

There are two major ways of selection in this system. On the one hand, open competitions for permanent officials, including the AD5 competition, open to holders of a licence or master's degree, with a final deadline of 10 March 2026. On the other hand, the CAST Permanent, a continuous open procedure for contract agents: applicants create a profile on the EU Careers platform, update it every six months, and can be invited to tests if their profile meets the needs of an institution. These two streams require separate preparations and different types of tests.

It is precisely for this reason that controlling the operation of EPSO before choosing its method of preparation is so important. Training on exercises unsuitable for the procedure is a considerable waste of time. For French-speaking candidates, the SGAE (Secretariat-General for European Affairs) is a reliable official entry point for obtaining information on careers in the European institutions and identifying the most appropriate procedure for its profile.

The two main entry routes: competition AD5 and CAST Permanent

To integrate the European institutions, there are two main ways for you, and they are fundamentally different in their logic, timing and demands. Confounding these two paths is one of the most common mistakes among beginners, and it can cost several weeks of unnecessary preparation.

Open competition AD5: the path of the incumbent official

The competition for AD5 administrators is open to holders of a licence or master's degree wishing to join the European institutions as permanent officials. This is the most selective, but also the most stable, route: the winners are on a reserve list and can be recruited as full holders. This competition follows a rigid and cyclical timetable. For the current cycle, the deadline for applications was 10 March 2026, which means that the demand for preparation concentrates sharply in the weeks preceding this window. The tests are particularly demanding: verbal, numerical and abstract reasoning tests, situational judgement, EUFTE professional writing tests, and finally a comprehensive evaluation centre including case studies, oral exercises and skill interviews.

The Permanent CAST: the continuous flow of contract

The permanent CAST works according to a radically different logic. There is no annual deadline: applicants submit a profile on the EPSO platform and must renew it every 6 months to remain active in the selection pool. If their profile meets the needs of an institution, they are then invited to take reasoning tests and skill tests, without an evaluation centre as developed as for AD5. This open logic makes the preparation for the CAST relevant at any time of the year, unlike the concentrated peaks of the AD5.

Choose your way before you start

Clearly identifying which path corresponds to your situation, your degree level, your career objective and your availability is an essential step before any serious preparation. A candidate who prepares the EUFTE exams and the evaluation centre without aiming for the AD5 contest loses valuable time. Conversely, a CAST candidate who does not have mastery of the numerical reasoning tests may be eliminated from the first selection. Platforms like EPSOHQ offer distinct and structured paths for each of these two routes, allowing you to concentrate your effort where it really counts.

The full course of the AD5 competition: from the application to the evaluation centre

Understanding the course of the AD5 competition is the first condition for effective preparation. This selection process is structured into four successive stages, each more demanding than the previous one, and only candidates who anticipate each phase with method manage to pass all the tests.

Step 1: Online application

It all starts on the official EU Careers platform, managed directly by EPSO. You need to create a personal account, then build up your application file by teaching your diplomas, professional experience and language choices. This last point is strategic: you must indicate your main language (Language 1) and your second working language (Language 2), and these choices will condition the entire process. For the 2026 cycle, the deadline for submission was 10 March 2026 at 12.00 Brussels time. An error or omission in the file may result in an immediate exclusion; Read the official competition notice in its entirety before you start entering your information.

Step 2: Computerized Screening Tests (CBT)

CBT tests are the first massive filter in the competition. Conducted in an approved testing centre, they include three batteries of timed questions: verbal reasoning, numerical reasoning and abstract reasoning. These tests measure your ability to quickly process complex information under time pressure, without the content of your field of study coming into play. Competition is extremely tight: the vast majority of candidates are eliminated at this stage. Intensive and regular training, based on repeated white tests and systematic error analysis, is essential to achieve the required selection scores.

Step 3: EUFTE tests

EUFTE tests evaluate your mastery of written expression in your main language. The aim is to draw up reasoned texts related to European policies: you must demonstrate your ability to structure a clear reflection, to mobilise relevant institutional knowledge and to express yourself accurately. The INSP has published a video dedicated to the exams of the AD5 Graduates competition, a sign that the French institutions today fully recognize the importance of this often neglected phase in the preparation of candidates.

Step 4: Evaluation Centre

The evaluation centre is the final and most multidimensional stage. Over an intensive day, you participate in case studies, oral presentations and structured interviews, all designed to measure the behavioural skills defined by EPSO: problem analysis and resolution, communication, teamwork and stress resistance. Evaluators observe your concrete behaviours, not just your theoretical knowledge.

The majority of Francophone resources available stop at the application phase and leave candidates without accompaniment for the decisive stages. This is precisely where the structured preparation proposed by EPSOHQ brings real value: CBT simulations, EUFTE writing exercises with feedback, and targeted training at the evaluation centre to approach each event with method and confidence.

CAST Permanent: how to optimize your profile and prepare for testing

The Permanent CAST is often described as the "without competition" entry route in the European institutions, but this simplification masks a more nuanced reality. Open all year round via the EU Careers portal, this open-ended procedure allows any candidate to register in a selection pool consulted directly by the institutions when a need for recruitment arises. Unlike the AD5 contest, there is no annual closing date: you can file your profile in January and August. This paradoxically creates a sense of false security, as many candidates register once, and then completely forget to actively manage their application.

The 6-month rule: fatal error not to be committed

The most critical point of the Permanent CAST is also the least documented in French. To remain active in the selection pool, each candidate must renew their profile every 6 months without exception. Failure to renew results in an automatic exclusion of the pool, regardless of the quality of your file or the length of your registration. In other words, a perfectly written profile, but not renewed in time, simply disappears from the research results of institutional recruiters. With over 70,000 candidates enrolled in the database based on available data, this renewal rule is a natural filter that few candidates anticipate.

Optimizing your profile: more than just an online CV

The CAST profile is not simply a copy-paste of his curriculum vitae. As explained in the practical guide on the functioning of the EU contractual agent status, the institutions consult the base via precise search criteria: the profile therefore functions as an algorithmic filter. Three levers determine your actual visibility. First, the choice of the functional domain: the four function groups (FG I to FG IV) correspond to distinct qualification levels, and poor positioning drastically reduces your chances of being contacted. Secondly, the use of keywords aligned with vacancy announcements published by the institutions, which reflect the exact vocabulary of recruiters. Thirdly, consistency between the reported experiences and the official criteria published by EPSO for each function group.

Tests identical to the AD5 contest: good news for your preparation

The CAST tests (verbal reason, numerical reasoning, abstract reasoning and, according to the profiles, situational judgment) are structurally identical to the CBT tests of the AD5 competition. This similarity is a major strategic information: if you are preparing for the AD5 competition with structured training modules, you are simultaneously preparing the CAST tests. The two channels share the same computer format, passed in an approved Prometric centre, with the same time constraints and the same logic of scoring. The preparation is therefore fully transferable from one procedure to the next, which represents a considerable advantage for applicants considering the two parallel channels.

However, there is a worrying fact that almost all the preparation resources available in French are concentrated on the AD5 competition, leaving CAST candidates without structured support in their native language. Specialized platforms like EPSOHQ gradually fill this gap by offering verbal and numerical reasoning modules directly applicable to both procedures, with flexible plans tailored to the needs of each candidate, from beginner to confirmed profile.

Compare preparation options: INSP, Sciences Po, self-training and online platform

Once you have understood the trials before you, the central question becomes: how to prepare effectively? The market for preparation for European competitions offers several ways, but not all of them are worth depending on your profile, budget and location.

INSP: a channel reserved for an institutional elite

The National Institute of Public Service, the successor of the ENA, does indeed incorporate a preparation for European Union competitions in its training offer. However, the primary purpose of the INSP is the training of senior national officials: its programmes are aimed primarily at agents already in the French administration or students who have entered the school by competition. For the vast majority of French candidates, whether they are students at the end of their master's degree, professionals in conversion or residents outside France, this path is structurally inaccessible. This is not an option to be ruled out because of lack of quality, on the contrary, but rather a device whose scope simply does not meet the needs of the ordinary candidate.

Sciences Po Paris: academic excellence, forced access

The Centre de Préparation aux Concours européennes (CPCE) de Sciences Po Paris, attached to the École des Affaires publiques, represents the most structured institutional option available to Francophones. Created in 2007, it has had strong results: since 2010, 60% of candidates who have passed the admission exams through this program have passed their Assessment Centre. The trainers are active European officials, having themselves passed the AD5 competition. However, several obstacles seriously limit its accessibility. The sessions are held on Saturday, January to April, exclusively in Paris (27, rue Saint-Guillaume, 75007). Training costs range from €0 to €450 for the eligibility phase and from €200 to €250 for the admission phase, along with indirect costs that are often invisible: transport, accommodation and leave for applicants located outside Île-de-France. For a candidate based in Lyon, Bordeaux or abroad, these combined constraints make training difficult.

Self-training: an attractive but structurally inadequate option

Some candidates try to prepare themselves, combining EPSO's official guides, the publications of the General Secretariat for European Affairs (SGAE) and free exercises found online. This is understandable, especially for budgetary reasons, but it has concrete limits. Without any educational progress built, the candidate does not know in what order to approach the modules or how to calibrate the intensity of his preparation. Without going back on his mistakes, he repeats the same incorrect reasoning patterns without knowing it. Public resources provide access to the format of the tests, but they are not a method of preparation. With nearly 175,000 applications for approximately 1,490 places on the reserve list of the AD5 2026 competition, improvisation of the teaching system is a difficult to justify.

Specialized online platforms: flexibility, structure and accessibility combined

Faced with the limitations of previous options, specialized digital platforms simultaneously meet the three accessibility criteria that other formats cannot meet: total geographic availability, time flexibility and reduced financial barriers. EPSOHQ thus offers structured modules covering numerical reasoning, free text writing, situational judgment and the estimation of salaries in the European institutions, with a pedagogical progression thought for beginners. The existence of a free plan is a decisive advantage: it allows any candidate to test the method and evaluate its real level before any financial commitment. Neither the INSP, Sciences Po, nor the editors of preparation manuals offer an equivalent entry point.

The decisive criterion for choosing the course of preparation is not the prestige of the institution, but the combination of three factors: the coverage of the actual tests of the competition, the practical accessibility (geographical, financial and temporal) and the quality of the pedagogical return. On these three dimensions combined, a specialized digital platform is required as the most coherent solution for the majority of Francophone candidates in 2026.

Remuneration in the European institutions: what you can hope to gain

The issue of remuneration is often the first issue raised by candidates interested in the European institutions, and it deserves a precise and structured answer. Understanding the pay system from the outset of your preparation allows you not only to set concrete goals, but also to assess the efforts to be made in view of the opportunities offered.

A salary scale regulated by the EU Staff Regulations

The remuneration of European civil servants is governed entirely by the European Union Staff Regulations, a regulatory text which defines precisely the grades, levels and salaries of civil servants. For an AD5 staff member in the first step, the basic salary is approximately EUR 4,900 gross per month. In addition to this amount, additional allowances can significantly affect the total income: the expatriation allowance (paid to staff working outside their country of origin), the household allowance and the dependent children's allowance. These supplements are not anecdotal; for a family profile with two children, the monthly total can easily exceed 6 000 euros, a figure regularly quoted in the specialized press to illustrate the financial attractiveness of these posts. You can consult all job offers and working conditions in the EU institutions on the official EU portal.

From crude to net: a calculation that requires a dedicated tool

The shift from gross to net salary is one of the most common sources of confusion among beginners. European officials are not subject to the national tax of their country of residence; Instead, they pay a specific EU Community tax, plus contributions to the European Health Insurance Scheme (EHI) and the institutions' own pension scheme. These deductions, whose rates differ significantly from the French national scales, make any approximate estimate unreliable. Without a suitable simulation tool, it is very difficult to anticipate what your future purchasing power represents.

The entry grade depends on your profile and experience

The level of pay at which you begin depends directly on the rank to which you are recruited and the step assigned to you. The generalist AD5 competitions are the standard entry point for Masters holders. Specialist profiles, including lawyers-linguists, economists or scientific specialists, can be recruited at higher grades such as AD6 or AD7, with significantly higher basic salary at first pay. EPSO evaluates the years of recognized professional experience to set your starting step within the grade, which can represent a difference of several hundred euros per month depending on your career.

Contract agents: a separate grid, the same benefits

For candidates moving to the Permanent CAST, the salary structure is different. Contract staff are classified into four functional groups (I-IV), corresponding to progressive levels of qualification and responsibility. Their salaries are generally lower than those of permanent staff in the AD category, but they enjoy the same European social benefits: sickness insurance, pension schemes and family allowances. To understand the different access routes and their conditions, the All Europe website offers a clear and regularly updated panorama.

Simulate your net salary before you start

Faced with the complexity of this system, EPSOHQ has developed a European salary estimation module that allows you to simulate your net remuneration according to your rank, step and family situation. No other Francophone preparation resource offers this tool, which turns abstract data into personalized and actionable financial projections. Even before you start preparing for reasoning or case studies, knowing exactly what you can expect to win is a fundamental step in building your European career project on a solid foundation.

EPSOHQ: your European digital training centre, accessible without conditions

After exploring the tests, recruitment routes and preparation options available on the market, it is time to present the solution that brings together all these dimensions in one place. EPSOHQ operates as a fully digital European training centre, designed specifically for EPSO candidates. The platform covers the entire selection process: numerical and verbal reasoning, free text writing (EUFTE), situational judgement, digital skills and EU salary estimation. No prior admission is required, no travel is required, and no paid subscription is required to begin. You arrive on the platform, you explore, and you start preparing immediately.

Structured free access, without equivalent in the Francophone sphere

What distinguishes EPSOHQ from the first contact is its free plan. Where institutional actors such as the INSP or Sciences Po reserve their preparation resources for their own students or registered students, and where most French-language business platforms condition access to a payment, EPSOHQ offers structured preparation modules accessible without credit cards. This free entry point is not just a limited overview: it provides a real pedagogical basis for any Francophone candidate to discover the types of events, test their initial level and build a realistic preparation strategy. For a beginner who discovers the world of European competitions, this immediate accessibility represents a concrete and decisive advantage.

Pro and institutional plans to go further

For candidates who wish to deepen their preparation, the Pro and institutional plans of EPSOHQ offer complete coverage of the AD5 and CAST Permanent events. The exercises are progressive: we start with introductory questions before dealing with more complex cases, which is suitable for both beginners and second attempt applicants seeking to correct their deficiencies. Each module includes detailed corrections and test-specific strategies, thematic flashcards and a test simulator for the EUFTE. This graduated approach avoids the frequent pitfall of cognitive overload, allowing the candidate to progress at his/her own pace with clear benchmarks.

A platform accessible from all over the Francophonie and beyond

One of the structural advantages of EPSOHQ is its total geographical accessibility. Unlike physical preparation centres concentrated in Brussels or Paris, EPSOHQ is accessible from any country, whether it is a member of the European Union or not. This feature is particularly valuable for Belgian, Luxembourg, Swiss and French-speaking African candidates who wish to join the European institutions without having local access to specialized training. The platform is available in several languages, including French, English, Italian, Spanish and Bulgarian, reflecting the international diversity of the EPSO candidate pool.

A preparation that fits your calendar, not the other way around

Finally, EPSOHQ is designed to adjust to the time constraints of each candidate. The AD5 competition follows a timetable announced in the EU Official Journal, which often requires intensive preparation over a few weeks. The permanent CAST, on the other hand, is a continuous procedure, renewable every six months, which requires a gradual construction of the profile over several months. These two very different logics are answered in the EPSOHQ "on request" model: modules are available at any time, without a mandatory session or registration deadline. Whether you have three weeks or six months, the platform adapts to you.

Practical tips for structuring your preparation for EPSO competitions

Success in EPSO competitions is not limited to the academic level of the candidate: it depends largely on the quality of the preparation put in place. Here are five structuring principles that will allow you to organize your effort in an effective and focused way.

Start with an honest diagnosis of your weaknesses

Before opening any manual or taking any training, perform complete white tests of numerical, verbal and abstract reasoning in conditions close to the exam. The objective is to identify precisely the types of questions where your success rate remains below 70%, as it is below this threshold that the risk of elimination is highest. Once these fragile areas have been mapped, focus your training time on these areas as a priority, rather than working uniformly on all subjects. This diagnostic approach prevents you from wasting precious weeks consolidating already solid skills.

Build your calendar from the event date

For an AD5 competition, CBT tests are usually held two to four months after the closing of applications. This window may seem comfortable, but it is actually very short if not planned upstream. Start from the expected date of the tests and go back week by week to define intermediate objectives: thematic revisions, timed test sessions, consolidation of the weaknesses identified during the initial diagnosis. A structured schedule reduces the risk of cognitive overload in the last few weeks and allows you to get to the tests in optimal readiness.

For the Permanent CAST, profile renewal is non-negotiable

The Permanent CAST requires a profile renewal every six months in the EU Careers system. This administrative detail is often underestimated, but it is absolutely critical: an unrenewed profile becomes inactive, which means you disappear from the selection pool and all your previous preparation efforts are nullified. As soon as you register, immediately schedule reminders in your digital calendar for each renewal deadline, and treat this step as seriously as the test preparation itself.

Practice exclusively in timed conditions

EPSO tests are explicitly designed to exert strong temporal pressure on candidates. Working without time constraint creates an illusion of mastery that does not resist the day of the real examination. Every training session must reproduce the official conditions: timer set, no interruption, interface similar to that of D-day. This training discipline conditions your ability to simultaneously manage accuracy and speed, two requirements that cannot be dissociated in EPSO competitions.

Combining technical training and European institutional culture

The reasoning exercises are necessary but insufficient. The EUFTE drafting tests, which represent a significant part of the final score, require a solid understanding of the functioning of the European institutions, the major Community policies and the current challenges of the Union. This dimension is not improvising: it is gradually being built in parallel with technical training, thanks to a regular reading of reliable institutional sources. A specialized platform such as EPSOHQ specifically integrates this dual dimension into its training courses, combining structured reasoning exercises and contextual content to prepare candidates for the entire selection process.

Next steps: start your preparation today

You now have a comprehensive overview to make an informed decision about your professional future in the European institutions. The main point is that EPSO organises two main access routes, the AD5 competition for permanent officials and the permanent CAST for contract staff. Each route requires a structured and specific preparation. Institutional options such as the INSP or Sciences Po provide a strong framework, but their accessibility remains limited geographically and financially.

The first concrete action to be taken today is simple: create a free account on EPSOQ. You immediately access the first modules of numerical and verbal reasoning, allowing you to evaluate your real level without any financial commitment. This diagnostic step is fundamental before building a coherent work plan.

Then clearly identify the procedure that fits your profile. If you are seeking a permanent position, head to the AD5 path and start your preparation well before the official opening of applications, the next cycle following a schedule similar to that of 2026. If you are looking for a first contractual experience, the CAST Permanent is available year round.

Finally, consult the EPSOHQ European salary calculation module to project your net remuneration according to your personal situation. Realising the benefits of a European career is a source of sustainable motivation throughout your preparation.

Conclusion

Success in an EPSO competition is not random. Thanks to the European Training Centre, you now have all the essential keys to tackle this adventure with confidence. Remember these basic points: structured preparation makes all the difference, choosing the accompanying formula must match your profile, and regularity in the work remains your best asset.

The European institutions are looking for motivated and well-prepared profiles. You can be one of those successful candidates.

Take action today. Explore the programmes offered by the European Training Centre, identify the formula that fits your objectives and start your preparation without delay. Your career in the European institutions begins with this first decisive step.
