Colorado's board of education passed a resolution Wednesday asking the legislature to pull out of a multi-state testing consortium and allow it to develop its own tests for public school students.
Republican members led by board chair Paul Lundeen passed the resolution by a 4-3 vote. Democrats all voted against the measure.
The resolution, which asks lawmakers to let the state's education department implement its own tests by spring 2015, has a slim chance of persuading the Democratically-controlled legislature to repeal tests developed by the Partnership for Assessment of Readiness for College and Careers, PARCC.
Lawmakers have already killed legislation that would have delayed the new statewide tests for a year pending a review of new Common Core standards.
