NAEP scores: Pre-Common Core improvement replaced by declines after Common Core was implemented

U.S. reading and math scores on the National Assessment of Educational Progress (NAEP) and other assessments have seen historic declines since most states implemented national Common Core English and math curriculum standards six years ago, according to a new study published by Pioneer Institute.

While Common Core was promoted as improving the international competitiveness of U.S. students in math, our international standing has remained low while the skills of average and lower performing American students have dropped in both math and reading.

Nationally, fourth- and eighth-grade NAEP math scores were rising gradually in the years before Common Core was implemented (2003-2013).  Post-Common Core, scores at both grades have fallen, eighth grade at nearly the same rate as it was previously increasing.

The declines are most acute for the lowest-achieving students, increasing inequality.  Scores for students at the 90^th percentile have mostly continued their pre-Common Core trend of gradual improvement. But the farther behind students were, the more substantial the declines, with the biggest drops occurring for those at the 25^th and 10^thpercentiles.

U.S. students fare better in reading than they do in math when compared to international competitors, but U.S. reading trends are similar to those seen in math, with gradual pre-Common Core improvement replaced by declines after Common Core was implemented.

From 2003 to 2013, national fourth- and eighth-grade reading scores were increasing at an average of about half of a point each year.  Since 2013, fourth-grade reading scores have been falling by less than half of a point each year, while eighth-grade scores have dropped by nearly a full point a year.

Rebarber also finds that Common Core is a product of the misguided progressive pedagogies and biases of the education establishment that developed it. “Several of us allied with Pioneer Institute have been pointing out, ever since it was introduced, the deeply flawed educational assumptions that permeate the Common Core and the many ways in which it is at odds with curriculum standards in top-achieving countries.”  Unfortunately, the disappointing results of Common Core—particularly for lower performing students—were predicted in 2010.

“Nearly a decade after states adopted Common Core, the empirical evidence makes it clear that these national standards have yielded underwhelming results for students,” said Pioneer Executive Director Jim Stergios. “The proponents of this expensive, legally questionable policy initiative have much to answer for.”

“It’s time for federal law to change to allow states as well as local school districts to try a broader range of approaches to reform,” added Rebarber.  “With a more bottom-up approach, more school systems will have the opportunity to choose curricula consistent with our international competitors and many decades of research on effective classroom teaching.”

State Analyses (See Appendix)

The study also includes summary analyses of pre- and post-Common Core performance in seven states: Massachusetts, California, Florida, Georgia, Illinois, Kentucky, and New York. These states, chosen mainly based on their size and geographic distribution, generally reveal a pattern similar to the national results.
