"The Common Core’s main selling point was that new, shared standards would ensure American students were learning at the same rates across state lines. Common standards – linked to common tests – would tell schools in Illinois how they stacked up against schools in Massachusetts or California.
"Now, as more states back out of the tests, the “common” in Common Core is threatened.
"In 2010, 45 states adopted the Common Core State Standards, a set of skills in math and English students should master in each grade. By 2012, they had all signed up for at least one of two federally funded, multi-state consortia charged with developing new online tests that would match the standards and be shared among the states. Today, that number is down to 36, as states have pulled out to design their own exams or dropped out of the Common Core altogether."
