Amanda Ripley:

So far this month in education news, a California court has decimated rigid job protections for teachers, and Oklahoma’s governor has abolished the most rigorous learning standards that state has ever had. Back and forth we go in America’s exhausting tug-of-war over schools—local versus federal control, union versus management, us versus them.

But something else is happening, too. Something that hasn’t made many headlines but has the potential to finally revolutionize education in ways these nasty feuds never will.

In a handful of statehouses and universities across the country, a few farsighted Americans are finally pursuing what the world’s smartest countries have found to be the most efficient education reform ever tried. They are making it harder to become a teacher. Ever so slowly, these legislators and educators are beginning to treat the preparation of teachers the way we treat the training of surgeons and pilots—rendering it dramatically more selective, practical, and rigorous. All of which could transform not only the quality of teaching in America but the way the rest of us think about school and learning.

Wisconsin took one very small step toward teacher content knowledge, MTEL a few years ago.
