Surprised at Germany, my niece goes to school in Stuttgart & my sis in law is always saying how how high & rigorous the standard is.

PISA tests aren’t intended for comparison, or to judge the quality of education. They test very specific things.

But there is still a table ranking countries individually & scoring on these specific criteria. It's very interesting to be honest. I'd imagine covid affected many countries dramatically.
