This data rewards schools that reject more applicants and/or fail more students (prevent them from graduating). Because that increases the average & median of their graduates. Charter schools and private schools do the same thing to increase test scores, but when controlling for other factors they are no better than public schools.
In order words, the data shows which schools do the best job of attracting and filtering out the top students. Many folks including some faculty think that IS their job - to set a high bar and see which few students can make it over, but from my point of view that is only half of the job - the other part, the hard part, is to actually educate students - to help more students get over that high bar.
