District officials said they are concerned about the adequacy of funding to implement the common standards.

More than half of school district officials in states that have adopted the Common Core State Standards said they agree that the new math and English/language arts standards are more rigorous than the ones they are replacing, according to a new study by the Center on Education Policy (CEP).

The report, Common Core Standards: Progress and Challenges in School Districts’ Implementation, reveals district leaders’ views about the impact of the Common Core standards and their progress and challenges in implementing the standards. It also found that the standards are moving closer to implementation in the districts that have adopted them.

School district officials said that parents, community members, and local educators appear to show relatively little resistance to the standards, and only 10 percent of districts in the adopting states consider resistance from teachers and principals to be a challenge in implementing the standards.

“Advocates have been concerned  about the extent to which the common standards would be embraced locally, so it’s good news that most district officials have positive views about the standards’ rigor and learning potential, and that they anticipate little community and educator resistance,” said Diane Stark Rentner, CEP’s director of national programs and a co-author of the study.

To date, 45 states and the District of Columbia have adopted the Common Core State Standards, which were released in June 2010 by the National Governors Association and the Council of Chief State School Officers.

Here’s how districts are taking actions to implement the Common Core standards, according to the report:
