But more seriously, grades do not correlate across schools in the slightest. The rigor of a public school in rural Kansas vs. a private school in NY could be wildly different. AP scores and SATs correlate well (same test for everyone that takes it), but normal grades do not
And good grades are already a prerequisite for admission, you generally need to averaging an A- average GPA to be competitive. schools want to see that you can balance a ton of things on your plate well (or your parents can afford to send you to classes/camps) rather than just optimize for a 5.0 GPA
Although I couldn't find any research on it for overall collegiate performance, the only research i could find in a short Google Scholar search found slight correlations between SAT performance and freshman year performance (but not overall).
That assumes students in rural Kansas have the same AP & SAT preparation as students in the elite NY private schools. The income disaparity between the two schools is probably quite noticable with one having more access to elite college prep than the other. By focusing purely on SAT scores and ignoring economic advantages you are discriminating against those from poor places without access to college prep. It's easy to be blind to that when you fall into the "elite NY private school" camp and have no idea how bad educational resources are in rural Kansas. It is a process of the elite admitting the elite and excluding the poor. You can tout how "fair" SAT scores are and how they equalize talent while conveniently ignoring you are just using it as a filter to keep out poor folks. The elite private NY school may send dozens of kids to HYP every year. The rural Kansas school may never send anyone to elite college in its entire existence. And it would be questionable if that rural Kansas school never had at least one student that would have excelled at an ivy (if given the same opportunities as students in the elite NY private school). Take the kids from the elite NY private school, strip them of their high parential income, put them into the rural Kansas school and take the kids in the rural Kansas school and put them into the elite NY private school with high parential income. Now see how many from each get admitted where.There are students at Harvard that have parential income of over $500,000. It wouldn't be unusual to find not one kid with the same parential income in the rural Kansas school.
It's not a value judgement and the SATs are far from perfect, but just another piece in the puzzle
And yea life isn't fair at the end of the day, nurture and nature are both super important for determining future achievement
Giving an explicit formula for scoring, along with a required score, has historically been the same as letting everyone in, because schools, over time, will always "teach to the test" so to speak.
First, the number of positions is limited, though I don't know how the limit is set or if it actually fills up.
Second, the top kids at the top high schools in the state go to the Ivy's, or other selective private colleges, even if they could get into UW. This leaves positions open at UW for a wider variety of students.
There is also a third tier system, consisting of community colleges that feed into the university system or provide shorter term job training.
Disclaimer: One kid is at the flagship college, the other is in high school.
Score = (score from exam at the school you want to go to * 2 + GPA + high school Math grade) / 4
That’s for engineering school. Every school has a different formula and holds its own exams. But the formula is public.
Sort all candidates, draw a line. When some of the selected people chose different schools, draw another line after a month.
We didn’t have an equivalent of SAT. But it can easily be plugged in a formula like this. There’s no studying to the test, since every school has a different test.
It's a system that can't be "gamed". (And, coincidentally, doesn't need to be gamed.) The idea was that it would take all the race, and the extra-curriculars, and the subjective stuff out of the system. And it did. But it also gave everyone admittance. Which is fine. Maybe everyone should get into college? I don't know?
My point is, when you have a set target, it's pretty much guaranteed that after a few years nearly everyone will be hitting that target. It's the nature of the beast.
