Common Core Will Take 24 Years to Show Improvement That Will Fall Way Short of NAEP Results from 1992 to Now

In a research report issued last week by Brookings, researchers found that states with CCSS-like standards have not scored as well as other states on the National Assessment for Educational Progress (NAEP).  

Brookings found “states with standards most different from the CCSS . . . gained the most on NAEP (p. 29).  Offering this dismal assessment of prospects for states adopting Common Core, the Brookings research estimates

it will take 24 years for a noticeable improvement to unfold. And that improvement would add up to 7.62 NAEP scale score points, a gain in 24 years that falls far short of the 22 point gain that NAEP registered in its first 23 years [without Common Core] (p. 32).
