Ranking - G-String-Legacy/GS_MV GitHub Wiki
Ranking students has been a time-honored method of quality control in educational institutions. Ranking students is achieved by mapping them according to their arithmetic mean score on a continuous linear scale between minimum and maximum possible score. Rankings are sometimes used for negative (fail), and positive selection (distinction).
Such rankings are considered crude predictors of future performance in areas tested. Most of us, though, would agree that no worthwhile competency is one-dimensional. But it is probably the only method that is both practical and defensible in court.
