English Proficiency Level Estimator (CEFR)

Estimate your CEFR English proficiency level (A1 through C2) by entering your self-assessed scores across five key language competency dimensions. Each dimension is scored 1–10.

Vocabulary Size / Range (1–10) 10,000 words)"> 1 = very basic (<500 words known), 10 = near-native (>10,000 words)

Grammar Accuracy (1–10)

1 = very frequent basic errors, 10 = consistently accurate with complex structures

Reading Comprehension (1–10)

1 = simple words/phrases only, 10 = understands all text types including implicit meaning

Listening Comprehension (1–10)

1 = very slow/clear speech only, 10 = understands any native speaker at natural speed

Speaking & Writing Fluency (1–10)

1 = isolated words/phrases, 10 = spontaneous, precise, nuanced expression

#### Formula

Composite Score = (Vocabulary × 0.25) + (Grammar × 0.20) + (Reading × 0.20) + (Listening × 0.20) + (Fluency × 0.15)

All inputs are on a 1–10 integer scale. The composite score (also 1–10) is then mapped to a CEFR band:

Composite Score CEFR Level Name

1.00 – 2.49A1Breakthrough 2.50 – 3.99A2Waystage 4.00 – 5.49B1Threshold 5.50 – 6.99B2Vantage 7.00 – 8.49C1Effective Operational Proficiency 8.50 – 10.00C2Mastery
