Well, I’m not JHS but I don’t think he or anyone else on this board is arguing that the SATs are the only way “to validate education.”
But as I noted above, for those applicants who are NOT home schooled, i.e., the vast majority, the SAT provides a quick thumbnail sketch of their high school as well as the individual. In fact, I personally think the aggregate score for the high school is a more valid measure of its quality than SATs are of an individual.
Plenty of kids never take an AP or SAT II test. Admittedly, it was a long time ago, but I arrived at a top college having never HEARD of AP tests. While today that’s less likely, not every high school in the US offers AP courses and it isn’t that easy to register for and take them if yours doesn’t. And please don’t tell me that as a homeschooler you were easily able to figure that out–not all parents, even very caring parents, have the resources to do that.
The very fact that almost every high school in American has a registration code for the SAT and/or the ACT means that there is at least SOME data available to a college about each high school. Yep, the high school profile SHOULD do that, but it often doesn’t–and the worse the high school, in general, the worse the profile.
And, in some cases, 6 AP classes and 2-3 SAT II scores might be excellent–even though the candidate has a serious educational deficiency, especially in math. I’m lousy at math, but I could do everything else well. I think the colleges to which I applied were entitled to know I was strictly average in math.
But, you say, there are grades. If you go to a lousy high school, you might have Bs and even some As because your high school grade inflates and/or you’ve had lousy math teachers.
Oh, and it’s definitely not an IQ test–not even close.
