The BestMyTest IELTS learner performance data is a free dataset about how our learners do in IELTS practice. It counts their answers, reviews, and recordings, and it shows where they gain and lose points. Our IELTS guide pages quote its figures. You can quote them too: the data is under a CC BY 4.0 license, so you only need to name BestMyTest as the source.
What the IELTS Learner Performance Data Covers
The data covers IELTS practice on BestMyTest from January 2020 to October 2026. It holds these figures:
- Correct-answer rates for each reading and listening question type
- How often learners reach each band in the sections of full practice tests
- Average criterion bands from our tutors and average scores from our AI for writing and speaking
- The most frequent writing corrections and the length of essays
- Speaking fluency and pronunciation figures from speech scoring
Each guide page gives the exact count behind each figure it quotes.
How the IELTS Learner Performance Data Is Measured
Every figure is a count or an average of real practice on BestMyTest. We recompute the data every three months. A question-type percentage is the number of correct answers divided by the questions answered. A criterion figure is the average band our tutors gave or the average score our AI gave, as the guide page says next to it. Recordings with no clear speech are left out of the averages and counted on their own. A correction category comes from the words the AI uses to explain each correction. The data holds no names, answers, or audio, only counts and scores.
IELTS Learner Performance Data Files
The figures and the anonymous rows behind them are published as files for researchers: one summary file and ten CSV files, such as tutor writing scores and practice-test section bands. Each row is one answer, review, recording, or test section, with its date and scores.
