The top colleges do monitor how kids from various high schools do in college. Most, not in great detail. But for a program like Landry, small and seeming to produce great kids, yes, they’d take a hard look at how they fare. It’s big that they aren’t accredited. And that they’re run by folks with no education background. I have no idea where they even get their ideas of what gets a kid into a top college. It’s more than some back story.
Some tippy tops can afford to take a chance on an occasional kid, track them, work with them, on academics and other. But there’s a lot we don’t know about these Landry kids, other than the few the article focuses on.
