Planning your preparation for EPSO/AD/426/25? Here's a structured timeline that covers the full journey from application to assessment centre.
Understanding the Selection Process
EPSO competitions follow a multi-stage process:
- Application & eligibility check — verify you meet the minimum qualifications and experience requirements
- Computer-Based Testing (CBT) — the multiple-choice field test (25 questions, 45 minutes)
- Talent Screener — scored self-assessment of your experience and qualifications
- Assessment Centre — case study, group exercise, structured interview (for those who pass CBT)
Recommended Timeline
8-12 weeks before CBT
Begin with a diagnostic assessment. Take a practice test without any preparation to identify your baseline. Most candidates score 8-12/25 on their first attempt — this is normal.
6-8 weeks before CBT
Focus on the highest-yield topics first: GDPR fundamentals, EU institutional framework, and the European Data Strategy. These collectively account for roughly 40% of questions.
4-6 weeks before CBT
Move to technical topics: EIF layers, FAIR principles, Data Governance Act vs Data Act distinctions, and AI Act risk classifications. Use spaced repetition for legislation articles.
2-4 weeks before CBT
Practice under timed conditions. Complete full 25-question tests in 45 minutes. Review incorrect answers and identify patterns in your weak areas.
Final week
Light review only. Focus on high-frequency topics and commonly confused pairs (DGA vs DA, consent vs legitimate interest). Avoid cramming new material.
Key Success Factors
- Read the Notice of Competition carefully — the syllabus is stated explicitly
- Practice in the EPSO format — familiarity with the question style matters
- Don't skip "soft" topics — EU institutional knowledge questions are often the easiest marks
- Time management — flag uncertain questions and return to them; never leave blanks (no negative marking)
