You must choose two of the 24 official EU languages. Language 1 (L1) must be at least C1 level and is used solely for the Reasoning tests. Language 2 (L2) must be at least B2 level, must be different from L1, and will be used for your EU Knowledge, Digital Skills, and Written Tests.
Strategic Insight: Based on the 2026 figures, L1 choices will closely mirror the largest applicant pools: Italian (79k+), Spanish (13k+), German (11k+), French (10k+), and Greek (10k+). For L2, because English is the primary working language of the EU institutions, it is the overwhelming favourite, followed by French and German.
