As they wait to see how the latest push for common national standards plays out, some states are putting off or slowing the revision of their own academic standards to avoid wasted effort and spending. At least four states--Arkansas, Florida, Louisiana, and Pennsylvania--have halted revision of their standards for mathematics or English/language arts, the subjects that standards writers for the national initiative are turning to first. At least three other states have throttled back similar efforts until the grade-by-grade, K-12 common standards are made final in the coming months. The National Governors Association and the Council of Chief State School Officers, which are overseeing the "Common Core" effort to develop more-uniform expectations for the nation's students, have already released a draft of college- and career-readiness standards for math and English/language arts. Experts writing the standards are also drafting grade-by-grade K-12 standards for math and English/language arts that are expected to be put in final form early next year. That's the document that many states are waiting to see before proceeding with work on their own standards.
