Good K-12 schools _do_ batch people by ability, though. The inner city schools -- the ones that are struggling, they do a poor job putting underperforming students into remedial courses. They similarly do a poor job putting high performing students into honors and AP/IB courses.

Measuring ability is tricky, which is why schools rely on grades for prerequisite courses. As a simple, contrived example: you can't really learn how to add if you don't even know your numbers yet.

I think you're right on about K-12 being lower level is also a massive factor. I coasted through K-12, personally. I know a lot of people who did. But college kicked my ass in a lot of ways. I would argue that for higher education, matching courses to ability is _even more_ important because what you're studying is that much more difficult.

Which good schools are you thinking of? Most schools don't really do any analysis to show that they're good or not. The others are either exam schools or schools in areas that are expensive. Given the correlation between socioeconomic status and school performance, that's also just selection bias.

I'm not necessarily against tracking (which is what we're describing) - but when you have a fixed number of resources and a mentality that the best should get more resources all you really end up with is a situation where the poor students are setup to fail.

Grades pretty much exist because we decided that they need to be out of the traditional school system by 20 or so (in most school systems you can only be held back a couple of times). I disagree with grades in general but that's another discussion.

This isn't really a scientific analysis, just basing that on my own lived experience and what I've learned from other people over the years.

I went to an inner city school. Inner city schools here offer fewer honors courses as compared to their suburban counterparts. My experience generally is that people who went to suburban schools are better educated. Suburban schools have higher graduation rates and kids get into college with more college credits than their urban peers.

Well yeah, I think we're in complete agreement that some schools just don't have enough resources to do what they need to do. The goal should be for every child to realize their full potential. For some kids, that means you need to move a little slower. For others, that means you need to challenge them.

I dunno, I think they are a useful metric for gauging ability in general terms. Not perfect. But I've yet to really see anything better.
