Focused practice for
EPSO CAST CBT
Verbal, numerical and abstract reasoning practice for CAST candidates who want a precise, no-noise preparation path. Built around the CBT reasoning tests EPSO lists for contract staff shortlisting — with final details always coming from EPSO.
The reasoning skills to train first
CAST preparation is narrower than AD5: focus on the reasoning CBT, then follow the specific instructions in your EPSO account.
Verbal Reasoning
Short policy-style passages, statement evaluation, and strict evidence discipline: true, false, or cannot be concluded from the text.
CBT reasoningNumerical Reasoning
Data interpretation with plausible distractors. Practice extraction, calculation and checking without wasting minutes on overwork.
CBT reasoningAbstract Reasoning
Shape sequences, rotations, counts and transformations. Train the pattern families so you can identify the rule fast.
CBT reasoningCAST prep without AD5 noise
Use this path if your priority is contract agent reasoning tests, not the full AD5 administrator package.
You received an EPSO CAST invitation
Use timed practice to tighten accuracy and speed before the CBT window shown in your EPSO account.
You are in a CAST shortlist process
Prepare while the recruiting service and EPSO handle the next steps. We train the reasoning part; EPSO confirms the procedure.
You registered for CAST and want to be ready
Build the core reasoning skills now, without assuming that registration alone means you will be invited to test.
CAST vs AD5: prepare the right scope
The reasoning skills overlap strongly. CAST preparation is narrower — three CBT reasoning areas, with any extra steps set by the notice.
| Test Component | CAST (Contract Agent) | AD5 (Administrator) |
|---|---|---|
| Verbal Reasoning | ✓ | ✓ |
| Numerical Reasoning | ✓ | ✓ |
| Abstract Reasoning | ✓ | ✓ |
| EU Knowledge MCQ | ✗ | ✓ |
| Digital Literacy MCQ | ✗ | ✓ |
| Written Essay (EUFTE) | ✗ | ✓ |
| Interview / further recruitment tests | Varies by notice | ✗ (AD5 2026) |
Preparing for CAST also helps with AD5 reasoning practice — but AD5 has extra sections that CAST candidates may not need. Explore AD5 preparation →
What the €79 CAST offer includes
Everything in this path is aimed at measurable CBT reasoning practice, not vague course content.
Focused diagnostic
Map your starting point across verbal, numerical and abstract reasoning so practice starts with your weakest area.
EPSO-style questions
Verbal passages, numerical tables and abstract patterns written for the same reasoning skills EPSO tests in CBT.
Targeted review
Questions you miss come back sooner. Strong areas take less space, weak patterns get repeated until they stop costing points.
Timed Exam Simulation
Practice under time pressure so you can check pace, accuracy and hesitation before any official EPSO testing window.

CAST preparation questions
Precise answers for candidates preparing for EPSO contract agent selection.
CAST CBT reasoning preparation should cover Verbal Reasoning, Numerical Reasoning, and Abstract Reasoning. The exact number of questions, timing, pass marks and any additional steps are set in each EPSO notice and in your EPSO account.
No. Registering in CAST creates or updates your candidate profile; it does not mean your eligibility has been validated, that you are shortlisted, or that you will receive a test invitation. EPSO and the recruiting service control invitations and final instructions.
CAST (Contract Agent Selection Tool) supports contract agent recruitment; AD5 selects permanent administrators. CAST reasoning preparation is narrower: verbal, numerical and abstract reasoning. AD5 also includes EU Knowledge, Digital Literacy and EUFTE written work.
Usually yes if you pass the reasoning tests and remain in the recruiting service process. The recruiting service may invite you to interviews and/or further job-related tests. Use Pass EPSO for reasoning preparation; use the official CAST notice, profile page and your EPSO account for the exact sequence.
For most CAST profiles, EPSO asks you to choose two different languages. Language 1 can be any of the 24 official EU languages and is used for the reasoning tests. Language 2 is usually English, French or German and may be assessed by the recruiting service during interviews or further tests. Always check the current Call for Expressions of Interest and your EPSO account.
Most candidates see meaningful improvement after 4–8 weeks of consistent daily practice (30–60 minutes/day). Verbal reasoning improves fastest with daily reading and comprehension drills. Numerical and abstract reasoning require pattern recognition skills that build with repetition. Pass EPSO's adaptive system focuses your time on your actual weak spots — not material you already know.
No. Publicly listed CAST sessions are indicative at programme level and matter only if you are invited or shortlisted for that testing round. Your personal booking window, platform instructions and test details come from EPSO directly.
For reasoning, yes. Verbal, numerical and abstract reasoning skills overlap strongly across EPSO CBT formats. CAST candidates should not spend time on AD5-only areas unless they are also preparing for AD5.
