4.13% to 15.54% in One Test — That is Not Fairness

That is a signal problem, not a score adjustment. When a June mock produces 4.13% top-grade students and a September mock produces 15.54%, the rubric has shifted, not the students. Band 8 on IELTS does not swing by a factor of nearly four between administrations, and neither should the CSAT. The Korea Institute for Curriculum and Evaluation needs to explain whether the standard is stable or if test-takers are now guessing which version of "standard" will show up in November.
