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.

I saw a post where they showed that ethnically native students in Northern Europe are doing just fine, it’s the non natives, which are up to 30% and even higher in som countries, that are doing poorly. Do they actually look at that in these studies or it’s swiped under the rug as something too inconvenient to discuss? If this is fake news, please correct me if you can show the real figures for this.

It's because it's inconvenient to discuss. What you said is the actual truth.

The really interesting thing was that when looking further, the results of non-native students reflected closely the scores of their native countries (not the countries where they now live), which is not at all surprising to me (as an immigrant, I don't think I am smarter because I now live in a "smarter" country even if I would love to be) but goes completely against everything people in the education sector appears to believe.

Mind showing a source for IQ declining across the world?

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

No serious person in the field agrees with this.

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.

Outside of science it seems to be that people measure intelligence as "what I feel I have" and nothing else.

Memorization and recall is a huge building block of intelligence itself. Almost everything we call intelligent has some kind of memory to store and work on problems. The more storage you have the more potential intelligence.

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

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.
