AI Writing Assessment by TeflToday
Grade student writing against CEFR levels (A1–C2) in seconds — not minutes. Get detailed feedback on grammar, vocabulary, cohesion, and task achievement, so you can focus on what AI can't do: teaching.
A single essay takes 15–20 minutes to grade properly. With 25 students submitting weekly, that is 6–8 hours of grading every week — often unpaid. The AI Writing CEFR Grader gives you that time back by handling the technical analysis, so you can add the human insight that actually helps students improve.
Teachers using TeflToday's CEFR grader report saving up to 85% of their marking time while providing more detailed feedback than before.
Every piece of writing is evaluated across six dimensions — the same criteria framework used by Cambridge English and aligned to the Council of Europe's CEFR descriptors.
Identifies specific error types — tense, articles, subject-verb agreement, prepositions — with corrections and explanations tailored to the student's CEFR level.
Assesses lexical range, word choice accuracy, and collocation usage. Highlights where vocabulary meets or falls short of the target CEFR level.
Evaluates paragraph structure, logical flow, use of linking devices, and overall text organisation — key criteria in Cambridge and IELTS assessments.
Measures how well the writing addresses the prompt, covers required points, and meets the expectations of the assigned task type (essay, email, report, review).
Provides a holistic CEFR level (A1–C2) based on all criteria combined, with a clear justification for the assigned level.
Delivers specific, prioritised suggestions for reaching the next CEFR level — so students know exactly what to work on.
Assign writing tasks, run them through the grader, and return detailed CEFR-aligned feedback the next day — instead of next week.
Grade practice essays against Cambridge criteria. Students see exactly where they stand and what they need to improve before exam day.
Use the grader to establish baseline writing levels and track student progress over a course — with objective, consistent CEFR benchmarks.
Share grader reports with students to build self-awareness and self-regulation. The detailed feedback turns passive feedback into active learning.
TeflToday was built by Ian L. Evans, a TEFL teacher with over 10 years of classroom experience. The CEFR Writing Grader isn't a generic AI tool — it's designed around the specific challenges of grading ESL writing in real teaching contexts.
It's part of a suite of 10 tools including the AI Lesson Plan Generator, Cambridge Exam Preparation tools, and 2 completely free tools. Read our in-depth guide on how to assess ESL writing using CEFR levels.
A CEFR writing grader is a tool that assesses student writing against the Common European Framework of Reference for Languages (CEFR) scale — from A1 (Beginner) to C2 (Proficiency). TeflToday's AI Writing CEFR Grader analyses grammar accuracy, vocabulary range, cohesion, coherence, and task achievement to produce a detailed assessment with an overall CEFR level and actionable feedback.
TeflToday's AI Writing CEFR Grader uses advanced language models calibrated to CEFR descriptors. It provides holistic scoring across multiple criteria (grammar, vocabulary, cohesion, task achievement) — the same criteria used by Cambridge examiners and IELTS assessors. While no AI replaces a teacher's professional judgment entirely, it handles the time-consuming technical analysis so you can focus on qualitative feedback.
Each assessment includes: an overall CEFR level (A1–C2), a breakdown of grammar accuracy and error types, vocabulary range and appropriacy analysis, cohesion and coherence evaluation, task achievement assessment, specific improvement suggestions, and collocation feedback. Teachers report that this level of detail would take 15–20 minutes per essay to produce manually.
Yes. The grader is calibrated to assess writing at levels corresponding to Cambridge English exams: A2 (KET), B1 (PET), B2 (FCE), C1 (CAE), and C2 (CPE). This makes it ideal for teachers preparing students for Cambridge writing papers.

Yes. The grader accurately assesses writing from A1 (simple sentences, basic vocabulary) through to C2 (sophisticated argumentation, nuanced language). It calibrates its expectations and feedback to the target level, so an A2 student receives age-appropriate suggestions rather than being held to C1 standards.
