Erudiam is a training platform for the EU selection procedures: EPSO competitions and the CAST selection. Behind that rather dry sentence sits a simple idea. Sitting an EU competition is a long, demanding and often lonely undertaking. We would rather nobody went through it underprepared purely for want of access to decent training.
This page sets out why we exist, how the platform is built, and what we hold ourselves to.
An EU competition means tens of thousands of applications for a few hundred places, procedures that keep evolving, and scattered, sometimes outdated information. Some candidates go in with people around them who have already sat the tests and know what is coming. Others start with nothing to go on. Two applications can look alike on paper and still not be running the same race.
That gap is the one we are trying to close. We want serious training to be within reach of as many people as possible, whatever country they live in, whatever language they think most easily in, whatever kit they happen to own. The platform runs in eight interface languages, on the web and on mobile, and given the choice we would rather add a way in than a hurdle.
The goal is not to pile on stress with anxiety-inducing league tables, but to take some away. Knowing what is coming, having already had a go at it, being able to see where you stand: that is what turns a test you dread into a test that is merely hard.
Complete training for the tests of the EU selections, from reasoning to EU knowledge, available on web and mobile, in eight interface languages.
Candidates for the EU competitions rarely have their days to themselves. They are already working, often full time. Many have children, a commute, evenings that are not entirely their own. Preparation has to slip into the gaps: a quarter of an hour on the train, ten minutes before a meeting that starts late, an hour in the evening once the house has gone quiet. Nobody has a computer to hand at moments like those.
So we did not want a tool that requires you to sit down at a desk. On phone and tablet, the daily training fits in one hand: the question of the day, a short set aimed at the test that keeps tripping you up, a review that spaced repetition brings back at the right moment. A session worth doing can last five minutes.
The day you want to work under real conditions, a computer is what you need. The exam itself happens on a screen, full screen, against the clock, with no interruption possible, and that is exactly what the real-conditions test reproduces. The two ways of working have nothing in common and do not call for the same device. Your progress, though, follows you from one to the other: in the evening on the sofa you pick up where you left off at your desk at lunchtime.
Our questions are built from the official EU sources, and every claim carries its reference and its verification date. That is not enough to make us infallible. In a question bank this size, mistakes get through: an article number that moved when a text was recast, a fine point of a standard read a little too quickly, a question that quietly goes out of date because the text behind it has changed.
Rather than pretend otherwise, we would sooner say it. Some parts of the bank are recent and still being built; where that is the case, we tell you before you start. And if a question looks wrong to you, flag it. We take it back, check it against the text, and correct it.
If you know the field, better still: send us your sources, the texts you would have relied on, what the test actually asked of you. Our best corrections come from candidates and practitioners who know their subject better than we do. That loop is one we mean to keep open: it moves the app forward more surely than any redesign decided from the inside.
These rules guide every page and every question on the platform. They are verifiable: most of them are locked by automated checks.
Erudiam is a European project, built in Europe for European candidates. The full identity of the publisher and the legal information are in the legal notice, kept up to date on this site.
A question, a correction to report, a suggestion, a disagreement with the way we have handled a topic? The contact page is there for that, and we read it. Candidate feedback shapes the roadmap directly.
