I wholeheartadly believe that new generations can't be forever better in everything than the previous ones. There will come a time of stagnation or even decline.

So there is absolutely nothing wrong in decline. It's mathematically necessary. (Well, stagnation, or slow increase is also possible.)

I also don't think that the only function of the education system is to score higher and higher on tests, it has so many other functions: keep kids happy, turn kids into happy adults, lower the tensions is society, create a better world for everyone, etc.

There wouldn't be much point of scoring better in tests if it resulted in unhappy kids, unhappy adults, broken society, broken world, now would it?
