OKLAHOMA CITY – An Oklahoma education advocacy group is taking heat for allegedly submitting petitions to save Common Core to the legislature with fraudulent names.

Stand for Children Oklahoma submitted 7,000 signatures – collected through Change.org – to lawmakers considering a repeal of Common Core in March, but parents who realized they were on the list are now saying they never signed the petition, News9 reports.

They’ve also found a few obviously fake names like Barrack Obama, and have confirmed that more than 1,000 names of those on the petition did not sign it, the news station reports.

“My second grader comes home frustrated with mat, because they want him to do five different methods and he only gets it one way,” Sherri Crawford, one of the mothers on the list who is adamantly opposed to Common Core, told News9.

“Several of the people I have talked to personally have said I never seen that email, nor am I on that e-mail list, I have no idea how they got my name,” said Kelli Dodd, another Common Core opponent who showed up on the list.

Stand for Children Government Affairs Director Amber England told News9 all those who signed the petition on Change.org were required to submit an e-mail for verification, and blamed the controversy on those who oppose Common Core.

“We obviously can’t control what people who don’t support higher standards do,” she said. “There are obviously people who try to sabotage the process.”

It’s unclear how or if the petition matters, as a Senate committee approved an amended version of a House bill to repeal Common Core that won approval in the lower chamber in a 78-12 vote.

“Our challenge is to ensure Oklahoma students complete their education with the English and math skills they’ll need for college, Career-Tech or to go directly into the workforce,” Oklahoma Senate Pro Temp Brian Bingman said in a statement, according to the City-Sentinel.

“House Bill 3399 ensures Oklahomans will be the ones to create the rigorous academic standards necessary so our children can compete in the 21st century without federal interference. This puts control squarely in the hands of Oklahoma and our local districts, helping make sure our students will receive the education necessary to succeed,” he said.

Oklahoma is among 24 states “where serious challenges to Common Core are under way,” the City-Sentinel reports.

Indiana recently became the first state to dump the national Common Core standards most states adopted in 2010 with financial encouragement from the Obama administration. States with intense opposition to the standards – from educators, parents, and politicians on both sides of the aisle – include New York, Wisconsin, Louisiana, Illinois and others, according to the news site.
