Earlier quoted context omitted.
The article is talking about supporting students who are admitted to a flagship school in their affirmative-action program despite being below the 25th percentile for students at that school. It specifically calls them out as being in the bottom quartile. It lists the human-interest protagonist's appallingly low standardized test scores. What more do you want here? According to http://www.parchment.com/c/college/coll…
It's an endemic problem - I heard that even at Ivy league schools nearly a quarter of the students are now below the 25th percentile.
update: for reference:
UT Austin 25th-75th percentile SAT math scores: 590 - 710
Cal Tech 25th-75th percentile SAT math scores: 770 - 800
How significant do you think it is that a quarter of Cal Tech students are below the 25th percentile? How far below do you think they range?
