When Jason Zimba was first hired to help write a new set of K-12 math standards in 2009, the groups behind the Common Core — including representatives from 48 states — set very ambitious goals. The tough new guidelines would match the expectations set for students in higher-performing rivals like Singapore and South Korea. The standards would not only catapult American students ahead of other developed nations but would also help close the gaps between low-income students in the U.S. and their wealthier counterparts.
The Common Core would drive publishers and test-makers to create better curricula and better tests and push school districts and teachers to aim for excellence, not just basic proficiency, for their students. And the guidelines would arm every principal, teacher and parent with the knowledge of exactly what it takes to get into college and succeed.
The champions of the Common Core — including organizations like the National Governors Association and the Council for Chief State School Officers — expected the task to be difficult. Overhauling textbooks would take a lot of time, and training teachers would take even more. But the bipartisan groundswell of opposition to the standards took them by surprise.
