When the rankings of the best school systems in the world were released earlier this year, Americans were shocked: our former number one standing slipped again, this time to number 26.
The rankings showed a new trend: the highest-performing school systems in the world are mostly in Asia.

There was no lively debate. The answer was clear: invest in teachers.
