IELTS Grammar Checker — common questions
What does the IELTS Grammar Checker do?+
Paste a Task 1 or Task 2 answer and it lists likely grammar errors, explains each one in plain English, and shows the corrected version. It targets the kinds of slips that affect Grammatical Range and Accuracy.
Does it give me a band score?+
No. This tool flags grammar and accuracy issues so you can fix them, but it does not assign a band. Band scoring weighs four criteria together and is best judged by a human teacher.
Which IELTS criterion does grammar affect?+
Grammatical Range and Accuracy, one of the four Writing criteria scored from 0 to 9. Examiners look at both the range of structures you use and how accurately you use them, so variety and correctness both matter.
Is this the same as a professional correction?+
No. This is a free automated self-check. A paid correction from a human teacher reviews all four criteria, your task structure and argument, and gives feedback tailored to your target band.
