Common Core came under attack on Thursday at the Conservative Political Action Conference, as a panel of two education experts outlined their issues with the educational standards. Getting out of federally funded testing programs and grassroots opposition were described as two important ways to roll back Common Core.

Despite Common Core’s unpopularity, conservatives are struggling to get the educational standards repealed. Many states had to adopt the standards in order to receive a waiver from now-impossible provisions of the old No Child Left Behind law from President Obama’s Department of Education.
