Bad news for supporters of national education curriculum: States with education standards most closely aligned to Common Core fared worse on math tests than states with their own standards, according to a new study.
The study, conducted by the Brookings Institution, compared standardized test scores for all 50 states over the last five years. It found that states using education standards that are most dissimilar to Common Core tended to score the highest on math.
Though the difference is small, it nevertheless undermines the claims of Common Core’s high profile backers, which include President Obama’s Department of Education, several moderate Republican governors, and the Bill and Melinda Gates Foundation.
“Supporters of Common Core argue that strong, effective standards will sweep away such skepticism by producing lasting, significant gains in student learning” wrote the study’s authors. “So far at least–and it is admittedly the early innings of a long ball game–there are no signs of such an impressive accomplishment.”
States that followed a hybrid approach to standards — utilizing some aspects of the Common Core and some aspects of their own standards — fared worse than both full-Common Core states and non-Common Core states.
