Our algorithm utilizes a two-stage adaptive methodology based on recognized lexical frequency profiling. By initially diagnosing your general word recognition scale, we can narrow down the exact linguistic bracket you fall into.
The second refinement stage asks targeted questions to pinpoint your active vocabulary size, aligning the results with the Common European Framework of Reference for Languages (CEFR).
Words are not created equal. Zipf's law demonstrates that a small subset of words makes up the vast majority of daily speech. Our test leverages this by testing you across categorized frequency bands, ensuring accurate estimation globally.
