I think there’s another point that’s kind of getting lost in the sauce here, which is that the SAT and ACT provide data about high schools, not just individual students.
Preliminarily, law school is a whole different kettle of fish than undergrad. Almost every candidate has 4 years of undergraduate education at an accredited college and the LSDAS folks have a process which both standardizes GPAs across institutions AND tells law school where the applicant 's GPA stands vs. the other law school applicants from the same college.The way in which it determines how one applicant’s GPA “stacks up” among other applicants from the same school doesn’t require the cooperation of the colleges.
It’s harder for colleges to get a grasp on high school applicants. There are many more high schools; there are far more students who attended secondary education institutions at which instruction was in a language other than English; there are more home school students. It’s just not feasible to standardize GPAs. Nor can colleges find out where most of the applicants stand vis a vis other college applicants from the same school. Look at the CDS for the most elite schools. At many of them, fewer than half those admitted submitted high school class ranks.
Add to this grade inflation. It’s bad in college, but it’s far worse in high schools.
So, what are colleges to do? They need some way to compare the applicants and the SAT and ACT provide one way to do this. Moreover, the fact that the college bound students from any given high school usually take this test gives the CB and colleges information about the high school. The public high school in my dad’s hometown–the only non-vocational high school in a city of over 100,000 many of whom are immigrants —has a median SAT score in the mid 400s (Out of 1600). My offspring’s public magnet alma mater, which also has many immigrants, has one of about 1460. Even if I know nothing more about these two high schools, I’m going to draw some conclusions about them.
There are all sorts of issues with AP tests too. But again, these provide standardized info for many college applicants. More importantly, they provide info about high schools. Colleges can buy high school profiles from the CB. These profiles tell CB how many students took AP exams, in which subjects, and how the students scored.
My offspring’s alma mater lists this information on its profile. It also lists the number of students who took each SAT II test and the median scores. Thus, I know that about 30% took the SAT II in chemistry and the median score was in the mid-700s. Again, this tells colleges info about this high school.
It might find out, for example, that the kid from an inner city school who scored a 650 on the Math 2c exam is the only kid from his high school to take it in the last 5 years and that the median math score on the “regular” SAT at that high school is a 420. That puts his score “in context.” And if you want to help the poor, you need to give context.
So, scrap the SAT and ACT and you not only do away with a tool that, IMO, is useful in assessing a kid’s readiness for college, you also do away with a means by which an admissions committee can get a quick, thumbnail sketch of the high school he attended.
