Which, to be fair, would be the definition of seeking to “not leaving any child behind”? (Hard to leave someone behind who is ahead?)
States had other school metrics (e.g., AP participation/results) available to monitor the other end of the “excellence” scale? Even before high school, in our state’s report cards, the number of kids performing above average, achieving high scores in standardized tests, was very much being watched by parents in school districts, or when assessing/selecting school districts before moving.
So furthering one group of students, doesn’t mean abandoning the other?
