Let me make a comparison.

If your manager says your performance is based on lines of code, you will be incentivized to write lots and lots of code. Does lots and lots of code mean you are being productive and making good software? Sometimes yes! Sometimes heaps of code means you are being ultraproductive and making amazing software. It could also mean you are writing much more code than you need to, introducing new bugs, not thinking about generalizing patterns, creating technical debt, making a worse UX, all of which I'm guessing you would agree are important to software engineering. But none of those things are going to matter in the lines of code metric.

So yes, sometimes having metrics for performance are worse than imperfect. Sometimes they are antithetical to the supposed goals. Student time is a zero sum game, and having a large portion of a crucial time in their development spent cramming for one metric is not going to have good outcomes for a society, only good outcomes for a metric.

The optimal amount of "teaching the students the actual subjects" you need to do to have them get good SAT scores is significantly higher than zero.

Sure, you can cram for SAT, and you can get gains on the metric from that. But you can't just cram all the answers into the students and have them get a perfect score via rote memorization. Students still have to learn things to be able to do well. Which is why SAT beats the "performance is based on lines of code" tier of shitty hilariously gameable metrics.

Out of curiosity, when was the last time you were involved in the school system? Things have changed a lot over decades what time previously spent "teaching the students the actual subjects" or time spent with extracurriculars continues to be eaten away by SAT prep. The downside of a bad score is now a disastrous outcome, and other parents have continued to optimize for the best score.

Oh, I don't doubt it that parents and students are optimizing for SAT outcomes themselves. You can't expect them not to. But no amount of SAT prepmaxxing can save you if you just genuinely know nothing - and having SAT is a huge upgrade over not having SAT. For one, it's a huge equalizer.

I've seen a few countries that went from "no standardized testing" to "full send standardized testing", and the benefits are too large to ignore. You can improve upon the tests, but removing them is a road to nowhere.

		I'm sure the introduction of standardized tests are an improvement upon a current system, but that's not really the point I am making. My point is the ongoing use and optimization of them leads to worse outcomes overall in terms of actual understanding of the material. > For one, it's a huge equalizer Could you explain this for me? It's nice that everyone is taking the same test but every piece of data I've seen points to a clear correlation between household income and SAT score, hardly an equalizer.
