Renew ICAO Level 4 – Plan Your Re-Evaluation in Time

Level 4 Expires After 4 Years

ICAO Level 4 (Operational) is valid for 4 years from the exam date. Before it expires, you must sit a re-evaluation. Without a valid language proficiency endorsement, you may no longer conduct English radiotelephony – your operational flexibility would be significantly restricted.

Tip: Plan your renewal 3–6 months before expiry. This gives you sufficient time for preparation and, if needed, a second attempt.

Seize the Opportunity: Upgrade to Level 5 or 6

The renewal exam is an ideal opportunity to aim for a higher level. Our Open Exam assesses your actual proficiency – you can achieve Level 4, 5 or 6.

Level 4

Valid 4 years. Re-evaluation required every 4 years.

Level 5

Valid 6 years. Two more years of peace – and lower costs long-term.

Level 6

Valid indefinitely. Never sit a renewal exam again – a one-time investment.

How to Prepare

Use our preparation tools: the Vocabulary Trainer for systematic vocabulary building, the Language Trainer for interactive practice and optionally the 1:1 coaching for targeted feedback from an experienced examiner.
