Inside the Algorithm: How Vibe Chat Assesses Your English

Ever wondered how a simple 10-minute test can accurately determine your English fluency? It's not magic—it's methodology.

At Vibe Chat, we've built our English Test to provide a quick yet reliable snapshot of your proficiency. Here is a look under the hood at how it works.

The Framework: CEFR

We don't invent our own levels. We align strictly with the Common European Framework of Reference for Languages (CEFR). This is the international gold standard.

• A Levels (Basic): Focus on survival English and simple interactions.
• B Levels (Independent): The bridge to fluency, covering complex thoughts and professional environments.
• C Levels (Proficient): Mastery, nuance, and near-native expression.

The Question Mix

To accurately place you on this scale, we can't just ask one type of question. Our test dynamically balances five categories:

1. Grammar & Structure

We test your grasp of rules not by asking you to recite them, but by asking you to apply them.

• Example: Identifying the correct verb tense in a complex conditional sentence.

2. Vocabulary in Context

Knowing a word is easy. Knowing when to use it is hard.

• Example: Choosing between "make" and "do" or "say" and "tell" in specific idioms.

3. Syntax (Word Order)

English has a strict word order compared to many languages. Our "scrambled sentence" tasks test your intuitive feel for sentence structure.

4. Reading Comprehension

Can you extract meaning from a paragraph? We present short texts and ask inference-based questions to test your reading speed and accuracy.

5. Error Analysis

This is the ultimate test of fluency. We show you a sentence that looks right but has one subtle flaw. Only advanced learners usually catch these.

Scoring & Leveling

Behind the scenes, each question is weighted by difficulty. Getting a difficult C1-level question right is worth more than a simple A1 question.

Your final score is calculated based on:

1. Accuracy: The percentage of correct answers.
2. Difficulty: The weighted value of the questions you faced.

This allows us to place you precisely on the A1-C2 spectrum.

What Next?

Your result is a starting point. Once you know your level, you can use Vibe Chat's other tools—like Text Polishing to refine your writing or Meeting Prep to practice speaking—to level up.
