As a candidate, President Donald Trump demonstrated his Republican bona fides by promising to get rid of Common Core educational standards.

But halfway through his first year, the Trump administration hasn't made much progress toward this goal. Thirty-nine states still use Common Core or a revised version of the standards as of June 12, 2017, according to the National Conference of State Legislatures.

In April, Trump ordered Education Secretary Betsy DeVos to conduct a review of the federal government's education-related regulations to assess whether they unlawfully interfere with state and local decision-making.

The review asks DeVos to modify or kill any regulations that the department considers problematic, but experts told us that this won't necessarily chip away at Common Core.

"The review in and of itself doesn't actually do anything," said Kelly McManus, government affairs director at the Education Trust, an advocacy organization. "The department has almost a year to put together a report on this and at that point we will see what they find and then what they do about it."

Individual states choose whether to adopt Common Core standards for their schools, and the federal government actually doesn't have control over that decision. So there's not much Trump can actually do.

The Every Student Succeeds Act, which President Barack Obama signed in 2015, bars the education secretary from incentivizing states to adopt any particular standards. So DeVos can't force states to adopt or reject Common Core or any other educational parameters, said Abigail Swisher, program associate with the Education Policy program at New America, a think tank.

Further, Trump's April executive order actually said that his administration's policy is to "protect and preserve State and local control over the curriculum" and "program of instruction."

We'll see what happens after the Trump administration finishes its review. But until then, we rate this promise Stalled.
