Precision assessment aligned with international standards, extremely high reference value for scoring

Keraft's intelligent English proficiency assessment system is built on the CEFR (Common European Framework of Reference for Languages). Learners only need 5 minutes to complete a full-level precise assessment from A1 to C2. The system automatically generates a multi-dimensional speaking ability profile covering pronunciation, grammar, fluency, and vocabulary, and dynamically plans a personalized learning path for each learner based on these results.

Per public research from Cambridge and ETS, AI speaking scoring technology delivers highly consistent results with human examiners, and Keraft's scoring system follows this same technical route. It is fully aligned with the four official IELTS scoring dimensions (fluency, lexical diversity, grammatical accuracy, pronunciation standardness), clearly displaying total speaking score and individual sub-scores, precisely marking core point deduction points, so learners can quickly identify their own ability gaps. In real testing, the scoring error compared to human IELTS examiners is ≤0.3 points, giving mock test scores extremely high reference value. The system also automatically analyzes user strengths and weaknesses, updates proficiency scores in real time, tracks every bit of progress, and scientifically builds exclusive learning paths, truly achieving accurate measurement, fast practice, and practical application, with every improvement clearly visible.
