Data are drawn from IELTS-first (n=3,638) and OET-first (n=1,879) test takers, with stratified random sampling used to construct balanced concordance and cross-validation sets (each n=1,000). The analysis includes test-choice distributions and professional group composition, highlighting differences between OET and IELTS representation within the
