 English Profile researchers developed the English Grammar Profile, which provides data-driven guidance on which grammatical features characterise learners’ output at each level of the Common European Framework of Reference for Languages (CEFR).Using data from the Cambridge Learner Corpus (CLC), the EGP has analysed which aspects of English Grammar - both structural and functional - are typically mastered at each CEFR level.This information is publicly available free-of-charge for non-commercial use on the English Profile site
