New Common Core assessments pass the bar for measuring the most important content in the standards (Morgan Polikoff, Brookings)

Few policy issues over the past several years have been as contentious as the rollout of new assessments aligned to the Common Core Standards (CCS). What began with more than 40 states working together to develop the next generation of assessments has devolved into a political mess. Fewer than 30 states remain in one of the two federally-funded consortia (PARCC and Smarter Balanced), and that number continues to dwindle. Nevertheless, millions of children have begun taking new tests, either from the consortia, ACT (their Aspire series), or a new state assessment constructed to measure student performance against the CCS or other college/career-ready standards.
