DENVER – The wave of opposition to the new Common Core learning standards has reached Colorado.

Opponents there are rallying behind new legislation that would “delay by one year the rollout of the new statewide assessments” that are aligned to both Common Core (which covers math and English standards)  and the state’s other revamped learning standards for science and social studies, reports’ ChalkBeat.org.

The bill – which is being sponsored by Republican state Sen. Vicki Marble – would create a state task force “to study implementation of the Colorado academic standards, including the Common Core,” ChalkBeat.org  notes. The task force would report its findings and make recommendations to state lawmakers and the Colorado State Board of Education by December 2015.

Marble’s bill would also authorize an outside group “to conduct a cost-benefit analysis of implementing the new standards and new tests,” ChalkBeat.org reports.

As Marble explained to Gazette.com, “The bill is intended to give Colorado the time it needs to explore Common Core in all aspects instead of handing over our children to an experimental education program with no proven track record of success.”

Marble is also considering legislation to ramp up privacy protections of student data that is generated, in part, by Common Core-aligned tests.

Republican state Rep. Frank McNulty has hinted he will soon offer legislation that would allow parents to opt their children out of state standardized tests, provided that their home school district offers standardized tests that are based on their own, unique learning standards, Gazette.com reports.

DenverPost.com credits this growing “backlash” to the efforts of a group “of concerned moms in Fort Collins (that) has networked with others around the state to express misgivings about the standards.”

One parent activist told the news site, “This was a top-down initiative. Now you have the bottom starting to push back up. That takes some time.”

While Common Core opponents can rejoice in the fact that their concerns are finally being heard in the state legislature after years of trying, ChalkBeat.org points out that so far, not a single Democratic lawmaker is on board with any of their delay efforts. That’s noteworthy because the Democrats control both chambers of the General Assembly, and Democratic Gov. John Hickenlooper is a staunch supporter of the Common Core experiment.

There may be one bright spot, however: The Colorado Education Association, the state’s teachers union, supports Common Core but is uneasy at the prospect that teachers’ job reviews will be, in part, connected to how well their students perform on the new, Common Core-aligned standardized tests, according to DenverPost.com.

CEA leaders are certainly aware that their peers in the New York teachers union recently came out against Common Core, at least in the manner in which it’s been implemented.

If the CEA follows suit and instructs its political handmaidens in the Democratic Party to support Marble’s delay proposal,  Common Core opponents may see lawmakers in both parties begin to take their concerns seriously.
