“Under Common Core, Federally Funded Study Shows Students’ Test Scores Have Sunk”

By Joy Pullman






In several cases student achievement reversed under Common Core, and in every subject studied students would have been better off if states had not adopted Common Core.

Excerpts from this article:


…“Contrary to our expectation, we found that [Common Core] had significant negative effects on 4th graders’ reading achievement during the 7 years after the adoption of the new standards, and had a significant negative effect on 8th graders’ math achievement 7 years after adoption based on analyses of NAEP composite scores,” the Center on Standards, Alignment, Instruction and Learning (C-SAIL) preliminary study said. “The size of these negative effects, however, was generally small.”


The researchers found not only lower student achievement since Common Core but also found by performing data analysis that students would have done better if Common Core had never existed. The achievement declines also grew worse over time, study coauthor Mengli Song told Chalkbeat, an education news website: “That’s a little troubling.”


Common Core is 640 pages of K-12 curriculum and testing mandates that nearly every state switched to between 2010 and 2013 under heavy federal pressure. President Obama, his education secretary Arne Duncan, and private financier Bill Gates promised the nation that overhauling what students learn and how it is measured would lead to student achievement gains.


It’s not that teachers didn’t work really hard to make Common Core succeed, either. C-SAIL’s report says “More than three quarters (76%) of teachers surveyed, for example, reported having changed at least half of their classroom instruction as a result of the CCSS, and about four out of five mathematics teachers (82%) and three out of four English teachers (72%) reported having changed more than half of their instructional materials in response to the CCSS.”


…Teachers and schools made massive, good-faith efforts to comply with Common Core. The problem is that those changes didn’t help kids.


If CC Never Happened, Kids Would Be Better Off

Last month, C-SAIL researchers presented their preliminary findings in this longitudinal study of student results from 2010 to 2017 (the latest data available). The presentation included the graphs below. [Please go to The Federalist Link to see the charts.]


The red dotted lines indicate how the researchers estimate students would have performed if the Obama administration had not imposed Common Core on the nation in 2010. Notice that in several cases achievement reversed under Common Core, and in every subject studied students would have been better off if states had not adopted Common Core. The effects are small, but in several cases statistically significant, and so far we only have about four years of results for after Common Core fully moved into schools…


Every state except four adopted Common Core between 2009 and 2013, and even those four shifted their curriculum and tests closer to Common Core. So to compare results, the researchers grouped those whose curriculum mandates were more similar to Common Core before it existed and then compared their results post-Common Core to those of states that used curriculum mandates less like Common Core beforehand. (Since there is no real control group available of non-Common Core states, then, this is about the best information we’re likely able to get.)


These preliminary results are from one of four studies that the C-SAIL received $10 million from taxpayers to conduct. The federal grant ends next year, which means researchers are nearing their final results.  C-SAIL’s staff and advisory board includes several well-known Common Core advocates.


We Could Have Predicted This (and Some Did)

C-SAIL’s is not the only study to find that Common Core has likely caused American students to learn less. The Pioneer Institute published dozens of studies by highly qualified authors arguing that was likely, all before Common Core had fully moved into place. They were ignored and even derided because they were providing independent research contradicting the Washington DC and long-standing American bipartisan groupthink that has driven U.S. education into the ground in the past half-century.


…There were earlier warning signs, too, of U.S. student achievement drops after Common Core and on a variety of tests. Former U.S. Department of Education official Ze’ev Wurman, for example, wrote in 2015:


The recent 2015 NAEP [Nation’s Report Card national] results showed a first ever significant decline of 2-3 points – about a quarter of a grade-level worth – in mathematics at both grades 4 and 8, and in grade 4 reading. The decline was broad and deep in most states with just a handful of exceptions, and even formerly excellent states like Massachusetts were not immune. But NAEP scores are only the most recent sign of decline.


The ACT scores have been stagnant in the last couple of years, but they show a slight decline since 2009.


The SAT scores stayed level since 2007, until they dropped this year on both verbal and math.


AP course taking in AB and BC calculus has been rising steadily over the years, yet the number of students who scored a passing grade this year – 3 and above – has plateaued in BC calculus and actually declined in AB calculus for many demographic groups.


Further, Common Core eliminated teaching of Algebra in many middle schools in states where they were adopted. Supporters argued that they will offer acceleration to Common Core’s slowed-down progression, where needed. Yet recent NAEP data shows that nationally, teaching Algebra in grade 8 dropped from 33 percent to 29 percent, the first drop in ten years.


In 2017, I wrote about U.S. students’ performance sliding post-Common Core on a well-known international test:


International test results released this week show U.S. students losing ground on yet another measure in the Common Core era, reading test results for fourth graders. On the Progress in International Reading Literacy Study, a comparison given every five years in 58 countries, U.S. fourth graders dropped from 556 in 2011 to 549 in 2016, out of 1,000 possible points.


This caused the United States to drop from fifth on the international comparison to 13th, even though the decline was within the margin of error (i.e., not statistically significant). The decline was even more pronounced among the lowest-performing American students. On this test, U.S. students have made no statistically significant improvement since 2001.



…Research shows that student achievement is directly linked with state and national economic health. Students’ performance on math tests “is a strong predictor of the state’s growth rate in GDP” per person, finds a 2016 Harvard University study. It found that improving U.S. students’ math achievement to just the “basic” level on the Nation’s Report Card could boost the U.S. economy by trillions of dollars long term. So Common Core may have cost the U.S. economy by depressing American kids’ math skills below what they would have been if states had refused to adopt Common Core.


U.S. Education: Elevating Incompetence Since 1965


…Bill Gates also admitted the same thing years after he used his mega billions and elevated social position to convince and fund the Obama administration to muscle Common Core into schools. Quote: “It would be great if our education stuff worked, but that we won’t know for probably a decade.” Obama is still considered a “scandal-less” president despite his administration’s linchpin efforts in forcing this scam on American families, teachers, and kids.


…Common Core cost taxpayers billions of dollars, teachers and students millions of hours, and possibly the U.S. economy and plenty of student achievement. People who say, “We have no idea whether something that cost billions of dollars and hours of teacher and student time will work” should lose all credibility and never be allowed near any position of power over other people’s children.


Instead, they fail upward. Dozens of people who created and pushed Common Core are laughing all the way to the bank, having cashed in their positions on the project for massive resumes and salaries. Dozens, if not hundreds, of vocal Common Core aiders and abetters hold positions of power throughout state education agencies, the U.S. Department of Education, education media and foundations, and teachers’ colleges nationwide. Is anyone ever going to drain this swamp?
