In the high-stakes world of international aviation, clear communication can mean the difference between routine operations and potential disasters. That’s why the International Civil Aviation Organization (ICAO) mandates English language proficiency for pilots, air traffic controllers, and other aviation personnel. But how exactly are ICAO English tests scored? Understanding the ICAO English test scoring process is crucial for any pilot aiming to achieve or maintain the required ICAO Level 4 proficiency – or higher. This comprehensive guide breaks down the scoring criteria, what examiners look for, and how you can prepare effectively. Whether you’re a student pilot gearing up for your first aviation English proficiency test or a seasoned professional renewing your certification, this pilot’s guide will equip you with the knowledge to succeed.
At ICAOSpeak, we specialize in accredited online ICAO English tests that align perfectly with these standards. Our expert examiners use the official ICAO language proficiency rating scale to ensure fair and accurate assessments. Ready to demystify the scoring? Let’s dive in.
Why ICAO English Proficiency Matters for Pilots
Before exploring how ICAO English tests are scored, it’s essential to understand the “why.” Since 2008, ICAO Annex 1 has required all pilots engaged in international flights to demonstrate at least ICAO Level 4 English proficiency. This isn’t just bureaucracy—it’s a safety imperative. Miscommunications in the cockpit or with air traffic control (ATC) have contributed to incidents worldwide, underscoring the need for reliable aviation English skills.
The ICAO English proficiency test evaluates six core skills: pronunciation, structure, vocabulary, fluency, comprehension, and interactions. These align with real-world aviation scenarios, from routine phraseology to handling emergencies. Scoring ensures that only those who can communicate effectively in voice-only environments—like radiotelephony—earn certification.
For pilots, achieving the right level means unrestricted operations. Level 4 requires reassessment every three years, Level 5 every six, and Level 6 is indefinite. But remember: the overall score is the lowest across the six skills—no averaging allowed. This holistic approach, detailed in ICAO Doc 9835, guarantees balanced proficiency.

The ICAO Language Proficiency Rating Scale: An Overview
The cornerstone of ICAO English test scoring is the ICAO language proficiency rating scale, a six-level framework from Pre-elementary (Level 1) to Expert (Level 6). Developed in ICAO Doc 9835: Manual on the Implementation of ICAO Language Proficiency Requirements, this scale provides detailed descriptors for each skill at every level.
Examiners—trained aviation English specialists—use these descriptors to rate your performance during the test, which typically lasts 20-45 minutes. The test format varies (e.g., interview-style via Zoom for online ICAO English tests), but the scoring remains consistent. Ratings are independent per skill, with the final proficiency level being the lowest score achieved.
Here’s a high-level breakdown of the levels:
| ICAO Level | Description | Reassessment Interval | Suitability for Pilots |
| Level 6: Expert | Near-native fluency; effortless communication in all contexts, including subtleties. | Indefinite | Ideal for international captains; no retests needed. |
| Level 5: Extended | Advanced proficiency; handles complexities with minor errors. | Every 6 years | Suitable for senior pilots; strong for leadership roles. |
| Level 4: Operational | Minimum for operations; effective in routine and non-routine scenarios with clarification. | Every 4 years | Required for all international flights; focus on maintenance. |
| Level 3: Pre-operational | Basic communication possible but frequent errors hinder safety. | N/A (below minimum) | Not sufficient; requires training to reach Level 4. |
| Level 2: Elementary | Limited vocabulary and structure; struggles with aviation topics. | N/A | Training essential; not operational. |
| Level 1: Pre-elementary | Performs only with great effort; unintelligible in most cases. | N/A | Starting point for intensive language courses. |
This table highlights why aiming for at least Level 4 is non-negotiable. For a deeper dive into these levels, read our blog on demystifying ICAO English levels from 1 to 6.

Breaking Down the Six Skills in ICAO English Test Scoring
Now, let’s examine the six skills that form the backbone of ICAO English test scoring. Each is assessed independently, with examiners noting how well you perform in aviation-relevant tasks like describing weather phenomena, role-playing emergencies, or responding to ATC instructions.
1. Pronunciation Scoring: Accent and Intelligibility
Pronunciation focuses on how clearly you articulate words, including stress, rhythm, and intonation. Examiners assess whether your first-language influence (e.g., non-native accent) interferes with understanding in an international aviation context.
- What Examiners Look For: Intelligibility for the aeronautical community. At Level 4, your accent may sometimes hinder ease but rarely prevents comprehension. Higher levels show minimal interference.
- Common Pitfalls: Overly heavy accents leading to misheard clearances (e.g., “cleared to land” sounding like “cleared to lend”).
- Tips to Improve: Practice shadowing native aviation audio, like ATC recordings. Record yourself reading phraseology from the ICAO Doc 4444 manual.
Detailed descriptors:
| Level | Pronunciation Descriptor |
| 6 | Almost never interferes with understanding; nuanced intonation for emphasis. |
| 5 | Rarely interferes; regional variations add flavor without confusion. |
| 4 | Sometimes interferes but controllable; intelligible in routine ops. |
| 3 | Frequently interferes, requiring repetition. |
| 2 | Usually unintelligible except for isolated words. |
| 1 | Performs at notional level; severe interference. |

2. Structure: Grammar and Sentence Patterns
Structure evaluates your use of grammatical patterns in aviation English. Basic structures (e.g., “Request taxi to runway 27”) must be controlled, while complex ones (e.g., explaining deviations) are tested in non-routine scenarios.
- What Examiners Look For: Creativity in basic patterns at Level 4, with errors rare and non-meaning-altering. At Level 6, both basic and complex structures are flawless.
- Aviation Examples: Errors like “I am descend now” instead of “I am descending now” could signal lower proficiency.
- Improvement Strategies: Study aviation English grammar rules specific to phraseology. Use apps for sentence-building exercises.
Descriptors table:
| Level | Structure Descriptor |
| 6 | Consistent control of basic and complex structures. |
| 5 | Basic well controlled; complex with occasional meaning errors. |
| 4 | Basic creatively used; errors rare in unexpected situations. |
| 3 | Basic not always controlled; errors frequently interfere. |
| 2 | Shows only limited control; errors cause misunderstanding. |
| 1 | Limited to memorized phrases; no evidence of structure. |

3. Vocabulary: Range and Accuracy in Aviation Contexts
Vocabulary assesses your word choice for common and work-related topics. Aviation-specific terms (e.g., “turbulence,” “holding pattern”) are key, along with paraphrasing ability.
- What Examiners Look For: At Level 4, sufficient range for concrete topics; successful paraphrasing when stuck. Level 6 demands idiomatic, nuanced usage.
- Pitfalls: Using general words like “bad weather” instead of “severe icing conditions.”
- Tips: Build your aviation English vocabulary with flashcards from ICAO glossaries. Practice describing scenarios without jargon.
| Level | Vocabulary Descriptor |
| 6 | Wide range; idiomatic and register-sensitive. |
| 5 | Sufficient for common topics; sometimes idiomatic. |
| 4 | Usually sufficient; often paraphrases successfully. |
| 3 | Limited range; inappropriate choices common. |
| 2 | Shows only basic range; unable to paraphrase. |
| 1 | Limited to memorized words. |

4. Fluency: Tempo, Pausing, and Flow
Fluency measures your ability to produce language at an appropriate pace (around 100 words per minute for aviation). Fillers (“um,” “you know”) and hesitations are evaluated.
- What Examiners Look For: At Level 4, stretches at tempo with occasional loss during transitions; fillers non-distracting. Level 6 is effortless with stylistic variation.
- Examples: Smooth narration of a flight diversion vs. halting speech under stress.
- Strategies: Time yourself reading ATC transcripts. Join conversation clubs for spontaneous practice.
Descriptors:
| Level | Fluency Descriptor |
| 6 | Natural flow; varies for effect. |
| 5 | Relative ease on familiar topics. |
| 4 | Appropriate tempo; occasional loss but effective. |
| 3 | Inappropriate phrasing; hesitations prevent communication. |
| 2 | Too slow; unable to sustain speech. |
| 1 | Disfluent; unable to produce stretches. |

5. Comprehension: Understanding Accents and Complications
Comprehension tests listening in aviation settings, from clear ATC to accented or stressed speech.
- What Examiners Look For: Mostly accurate at Level 4 for intelligible accents; slower with complications. Level 6 comprehends subtleties.
- Pitfalls: Failing to grasp non-routine events like “bird strike.”
- Tips: Listen to diverse accents on podcasts like “Aviation English Radio.”
| Level | Comprehension Descriptor |
| 6 | Accurate in nearly all contexts, including subtleties. |
| 5 | Accurate on work topics; mostly with complications. |
| 4 | Mostly accurate on common topics; may need clarification. |
| 3 | Often accurate but fails with turns of events. |
| 2 | Limited to simple, repeated messages. |
| 1 | No practical comprehension. |
6. Interactions: Managing Exchanges and Misunderstandings
Interactions covers turn-taking, clarification, and relationship management in dialogues.
- What Examiners Look For: Immediate, appropriate responses at Level 4; handles misunderstandings via checking/clarifying.
- Examples: Politely querying “Say again” without frustration.
- Tips: Role-play with partners simulating ATC-pilot exchanges.
| Level | Interactions Descriptor |
| 6 | Ease in all situations; sensitive to cues. |
| 5 | Immediate, informative; manages relationship. |
| 4 | Usually immediate; deals with misunderstandings adequately. |
| 3 | Sometimes immediate; inadequate with unexpected events. |
| 2 | Limited responses; unable to initiate. |
| 1 | Minimal interaction. |
