Tom Loveless of the Brookings Institution has studied student achievement for many years. He has written several reports on the National Assessment of Educational Progress (NAEP). Before earning his doctorate, he taught sixth grade in California.

In this post, he explains why “reformers” who confuse NAEP’s “proficient level” with “grade level” are wrong.

This claim has been asserted by pundits like Campbell Brown of The 74, Michelle Rhee, and organizations such as Achieve. They want the public to believe that our public schools are failing miserably, and our kids are woefully dumb. But Loveless shows why they are wrong.

He writes:

Equating NAEP proficiency with grade level is bogus. Indeed, the validity of the achievement levels themselves is questionable. They immediately came under fire in reviews by the U.S. Government Accountability Office, the National Academy of Sciences, and the National Academy of Education.[1] The National Academy of Sciences report was particularly scathing, labeling NAEP’s achievement levels as “fundamentally flawed.”

Despite warnings of NAEP authorities and critical reviews from scholars, some commentators, typically from advocacy groups, continue to confound NAEP proficient with grade level. Organizations that support school reform, such as Achieve Inc. and Students First, prominently misuse the term on their websites. Achieve presses states to adopt cut points aligned with NAEP proficient as part of new Common Core-based accountability systems. Achieve argues that this will inform parents whether children “can do grade level work.” No, it will not. That claim is misleading.

The expectation that all students might one day reach 100% proficiency on the NAEP is completely unrealistic. It has not happened in any other country, including the highest performing. Not even our very top students taught by our very best teachers haven’t reached 100% proficiency. This is a myth that should be discarded.

Loveless goes even farther and insists that NAEP achievement levels should not be the benchmark for student progress.

He warns:

Confounding NAEP proficient with grade-level is uninformed. Designating NAEP proficient as the achievement benchmark for accountability systems is certainly not cautious use. If high school students are required to meet NAEP proficient to graduate from high school, large numbers will fail. If middle and elementary school students are forced to repeat grades because they fall short of a standard anchored to NAEP proficient, vast numbers will repeat grades.

Anyone who claims that NAEP proficient is the same as grade level should not be taken seriously. Loveless doesn’t point out that the designers of the Common Core tests decided to align their “passing mark” with NAEP proficient, which explains why 70% of students typically fails the PARCC and the SBAC tests. Bear in mind that the passing mark (the cut score) can be arbitrarily set anywhere–so that all the students “pass,” no students pass, or some set percentage will pass. That’s because the questions have been pre-tested, and test developers know their level of difficulty. And that is why U.S. Secretary of Education John King, when he was New York Commissioner of Education, predicted that only 30% of the students who took the state tests would “pass.” He was uncannily accurate because he already knew that the test was designed to “fail” 70%.

He concludes:

NAEP proficient is not synonymous with grade level. NAEP officials urge that proficient not be interpreted as reflecting grade level work. It is a standard set much higher than that. Scholarly panels have reviewed the NAEP achievement standards and found them flawed. The highest scoring nations of the world would appear to be mediocre or poor performers if judged by the NAEP proficient standard. Even large numbers of U.S. calculus students fall short.

As states consider building benchmarks for student performance into accountability systems, they should not use NAEP proficient—or any standard aligned with NAEP proficient—as a benchmark. It is an unreasonable expectation, one that ill serves America’s students, parents, and teachers–and the effort to improve America’s schools.
