There’s nothing more tiresome than when a Cabinet secretary holds a major news conference when there is no news to announce. It is like the obligatory press conference of the NFL coach of a losing team after his team has lost again. On Tuesday, the U.S. Secretary of Education billed the release of the test scores on worldwide education called the Program for International Student Assessment (PISA) exams as a global event, even though the real news is that there is no news at all. The results revealed that U.S. schools are stagnant, stuck in a second tier of underperforming nations as others race ahead.
