Is there a tool that scores my IELTS Speaking answers by fluency, grammar and vocabulary?

A practice tool can score your answer along the four lines the examiner uses, which turns a vague feeling of "my vocabulary is weak" into moments you can replay. It cannot issue an official band score: those come from trained, certificated examiners who assess the recorded interview against fluency and coherence, lexical resource, grammatical range and accuracy, and pronunciation, each worth a quarter of the score.

Apps and practice tools can score a transcript against the same four criteria - fluency and coherence, lexical resource, grammatical range and accuracy, and pronunciation - and show you where the pattern breaks, but the number they print is an estimate for practice, not an official band. Official IELTS Speaking band scores are awarded by trained and certificated examiners who assess the recorded interview. Use a tool to find the two weakest moments in your own recording, then check the upgrade yourself against the descriptor wording.
