The data cited are international organizations so they are generally pretty trustworthy. However looking at the data tells a very different story from what this professor is claiming. They are averaging all countries regardless of context. Including countries at war, countries who have inconsistent data, etc. Not to mention all the different educational systems. Looking at each country though the results are fairly consistent from 2000 to 2022.
