WASHINGTON — Home-schooling mom Jenni White gave some of the loudest cheers when Oklahoma Gov. Mary Fallin signed legislation to repeal the Common Core education standards.

White, president of Restore Oklahoma Public Education, helped organize rallies, robo calls and letters to legislators encouraging the repeal. “You name it. We had to do it,” White said. “We just had to do it out of a shoestring budget out of our own accounts.”

In Oklahoma and elsewhere, home-schooling parents, often with their kids, are a frequent presence at legislative hearings and other political functions representing anti-Common Core forces. Sometimes, as in White’s case, they are even leading the opposition.

Home-schooling parents can teach their kids what they choose, but many of these parents still have a big beef with the standards.

Facebook groups such as “Home Schooling Without Common Core,” have popped up. A Home School Legal Defense Association produced video on the standards has been viewed online hundreds of thousands of times.

“All parents should be concerned about this. This is our children. To me, it’s not political,” said Megan King of Lawrence, Kan. She pulled two of her three sons out of their public elementary school, in part, because of the math standards, and co-founded Kansans Against Common Core.

The standards, adopted in more than 40 states and the District of Columbia, spell out what math and English skills public school students should master at each grade. They were pushed by governors concerned that too few graduates were ready for life after high school.

Use of the standards has become a hot-button issue in many states, and governors in Indiana and South Carolina recently signed legislation repealing them. The issue has pitted Chamber of Commerce-aligned Republicans with grassroots conservatives, including many home-schooling parents.

The concern that the more education policy is centralized, “the less control they have as citizens” motivates many of these home-schooling parents, said Emmett McGroarty of the conservative American Principles Project.

Some of these parents, like King, believe the standards are poorly designed. King said she believes the math standards are developmentally inappropriate for younger kids, not rigorous enough for older students.
