@michaeluwill I have worked with undergraduates from multiple schools, at multiple colleges, and I have worked with kids from private “elite” high schools in the Chicagoland area (The Lab School, Latin School, etc), as well as with kids who attended the public magnet schools, including IMSA, Payton, Lane Tech and others. I am also familiar with the Davidson Academy.
I can tell you that, academically, the kids attending the magnet schools are better than the kids attending the private schools. Yet The Latin School has placed more kids in “elite” colleges than either IMSA or Payton. Yet the accomplishments of the students of the Latin School do not come even close to those pf the public magnet schools.
Hell, compare the SAT/ACT and AP scores of the students at Taft to those at Davidson.
Mean SAT Reading & Writing
Taft: 680
Davidson: 751
Mean SAT Math
Taft: 690
Davidson: 778
Mean ACT Composite:
Taft: 30.1
Davidson: 34.8
AP scores:
Taft: 65% 4 or 5, 83% 3 or higher
Davidson: 86% 4 or 5, 99% 3 or higher
Where students matriculated:
Tafts: At least 2% matriculated to MIT or Stanford, least 13% matriculated to an Ivy, at least 75% matriculated to private colleges, and at least 75% matriculated to an “elite” college, private or public.
Davidson: Almost 13% matriculated to MIT or Stanford, 6% matriculated to an Ivy, about 55% matriculated to a private school, 61% matriculated to an “elite” college, private or public.
Although Davidson has, unquestionably, students who are academically superior to those of Taft (all have been designated "highly/profoundly gifted), it matriculates far fewer students to Ivies and other “elites”. They only matriculate more students to the two colleges which either do not consider legacy (MIT), or are not part of the East Coast “elite” high school => “elite” pipeline (Stanford).
Not trying to dump on Taft, I selected since it had the data easily accessible, and it’s a very good high school, but not ranked in the “top 5”, whereas Davidson is, arguably, the most selective public high school in the USA.
