AI Writing Assessment by TeflToday

CEFR Writing Grader for ESL Students

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.

CEFR A1–C2 Holistic + Analytic Scoring Cambridge Aligned Unlimited Essays

Grading Writing Is the Biggest Time Drain in TEFL

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.

What the AI Writing CEFR Grader Assesses

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.

Grammar Accuracy

Identifies specific error types — tense, articles, subject-verb agreement, prepositions — with corrections and explanations tailored to the student's CEFR level.

Vocabulary Range & Appropriacy

Assesses lexical range, word choice accuracy, and collocation usage. Highlights where vocabulary meets or falls short of the target CEFR level.

Cohesion & Coherence

Evaluates paragraph structure, logical flow, use of linking devices, and overall text organisation — key criteria in Cambridge and IELTS assessments.

Task Achievement

Measures how well the writing addresses the prompt, covers required points, and meets the expectations of the assigned task type (essay, email, report, review).

Overall CEFR Level

Provides a holistic CEFR level (A1–C2) based on all criteria combined, with a clear justification for the assigned level.

Actionable Improvement Plan

Delivers specific, prioritised suggestions for reaching the next CEFR level — so students know exactly what to work on.

Frequently Asked Questions

What is a CEFR writing grader?

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.

How accurate is AI-powered CEFR writing assessment?

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.

What feedback does the CEFR writing grader provide?

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.

Can I use it for Cambridge exam writing preparation?

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.

How many essays can I grade?

The AI Writing CEFR Grader is part of TeflToday's premium suite at €6/month, which includes unlimited use of all 8 premium tools. No per-essay limits, no contracts, cancel anytime.

Is the CEFR writing grader suitable for all ESL levels?

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.
