Some rankings might place the US relatively high in certain areas (like higher education), while others might place it lower overall, particularly when compared to other developed nations in areas like K-12 performance on international standardized tests. For example, the US often scores lower than many other developed countries on tests like PISA (Programme for International Student Assessment).
In short, the answer is complex and depends on the specific criteria used for the ranking. To get a more precise answer, you would need to specify which ranking system or metric you are interested in.
