OKLAHOMA CITY – Opponents of the Common Core experiment are putting Oklahoma Gov. Mary Fallin on the hot seat.

Today, a collection of anti-Common Core groups and activists are releasing a public letter they’ve sent to Fallin, asking the Republican governor to pull the plug on the nationalized K-12 learning standards.

They’re focusing on Fallin because she serves as the chairwoman of the National Governors Association, the organization that co-created the one-size-fits-all math and English standards and helped foist them unto America’s K-12 schools.

The letter-writing effort was coordinated by the American Principles Project (APP), and includes signatories from the Eagle Forum, the Pioneer Institute, the Home School Legal Defense Association, Concerned Women for America and other like-minded groups and individuals, reports Breitbart.com.

In its letter, the APP-led group explains to Fallin that the National Governors Association (NGA) has enabled “corporations and other private interests to drive education policy” and helped compromise “the power of parents.”

“(The NGA) has enlisted the power of the federal government to bring about these changes and, in doing so, has weakened the power of the states to defend the authority and rights of parents and other citizens.”

The group tells Fallin that Common Core math standards are “defective,” adding that they fail to prepare K-12 students for college-level study in the STEM subjects of science, technology, engineering, and math.

The group says the English standards are equally as bad, because they “fail to prepare children for authentic college work in the humanities and … weaken the formation of strong citizen-leaders and individuals of substance who are fully capable of exercising their liberties.”

The letter ends by asking Fallin, as chair of the NGA, to “end the Common Core project” and warning that her action (or inaction) on the issue will “define” her legacy.

It’s unclear if Fallin could end Common Core singlehandedly even if she wanted to (which she apparently doesn’t). Not only does another group – the Council of Chief State School Officers – co-own the standards, but the learning objectives have been adopted and embedded into the public education systems in 45 states.

In other words, it seems beyond Fallin’s power to rollback four years of K-12 policies.

But that doesn’t mean the group is wrong to try.

The best case scenario – should Fallin agree and find a way to end the NGA’s involvement with the Common Core experiment – is that there wouldn’t be a centralized organization to update the learning standards in future years.

At that point, states might start changing their learning standards to fit their own K-12 needs, thus reestablishing state control over public education.

With its letter to Fallin, it’s clear anti-Common Core activists aren’t dropping this issue, even though many states will soon be ending their legislative sessions for the year. Instead, they’re playing the long game, which is great news because political progressives have an agenda that is crafted in terms of decades instead of years or election cycles.
