Required exam map

Train in selection order. The first two stages are separate tests and use different scoring rules.

1. Cognitive reasoning gate

24 preguntas · 36 minutos · numerical, inductive and deductive reasoning

Threshold: at least the 40th percentile of the benchmark population.

The notice does not name the external provider. EPSOHQ G+ is the closest format-equivalent mock: same 24-question total, same three reasoning families and same 36-minute clock.

2. Conocimientos sobre la UE ranking test

30 questions · 40 minutes · pass score 15/30

EU institutional setup; Commission treaty roles and powers; Commission governance, decision-making and procedures; Commission policy priorities.

Only candidates with the pass mark and one of the highest scores progress, up to 2.5 times the 70 reserve-list places.

3. Ejercicio escrito

90 minutes · pass score 26/50

Document-based summary report, minutes, letter or note. Assesses critical thinking, analysis, creative problem-solving and written communication.

Marked only for candidates who pass and rank high enough in the Conocimientos sobre la UE MCQ. Both tests take place online on the same day.
