   There is a very high correlation between national IQ and PISA scores. We know that IQ is declining across the world, and it is declining because fertility and IQ are negatively associated. It's likely that declining IQ is a nontrivial factor for why PISA scores are declining. It is unfortunately still taboo to talk about this. Which is bad, because we can't hope to do anything about it if we don't face the truth.

      IQ is not measure of intelligence, it's more like curriculum test if you go into history of test and how it started.

         I think there is ample evidence IQ correlates with lots of things like job success, performance in mental work, income etc to the point the military and many organizations require an IQ test for sensitive tasks. To dismiss it as curriculum memorization, which I think is what you are hinting at, is demonstrably incorrect.

            It's not clear to me why you believe those two claims are in opposition.
