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.
How about this, an IQ test developed in the society you have to survive in is a good indicator of outcomes.
If you want to be a pendant about it then there is no such thing as a comprehensive intelligence test at all as there is no universally agreed upon definition of intelligence. But that's not very useful either.
