The future suddenly looks so much brighter for U.S. students in kindergarten through high school, thanks to a call for common learning standards in English and mathematics. If educators embrace the proposal, children deemed proficient in math in one state would no longer risk failing if the family moves to another. The plan would replace the crazy-quilt pattern of wildly varying tests and proficiency thresholds maintained by different states —differences that have held American children back for far too long. “Common core” academic standards would help get us to the momentous improvements that were pursued by Presidents George H.W. Bush and Bill Clinton before President Obama took up the charge.
