The Network for Public Educatuon just released a careful analysis of the latest CREDO study, which claimed that charter schools get better results than public schools.

Not so fast, writes Carol Burris, executive director of NPE. Burris reviewed the data and methodology and found multiple problems with both. The statistical differences between the two sectors, she saw, were the same in 2023 as in CREDO’s first charter study in 2013, which were then described as insignificant.

Even more troubling, CREDO’s work is funded by pro-charter billionaires. How is this different from a study of nicotine safety funded by the tobacco industry? And yet mainstream media accepted the CREDO report without questioning its data, its methodology, or its funders.

Billionaires behind the bias: Unmasking CREDO’s agenda

The Network for Public Education released a response to CREDO’s third national report, revealing the true agenda of a research arm of the conservative Hoover Institution. In its report, CREDO uses cherry-picked charter management chains and flawed methodology that embellishes results and discredits public schools and “mom and pop” charter schools.

NEW YORK, NY — Today, the Network for Public Education released ‘In Fact or Fallacy? An In-Depth Critique of the CREDO 2023 National Report a well-researched response that traces the funders and the bias in CREDO’s data, reporting methods, and conclusions.

CREDO’s report is meant to compare test score growth in math and reading for students in charter versus public schools. But once the curtain is pulled back, the conclusions are dangerously misleading to the public as well as policymakers who depend on accurate research to make informed education-related decisions and policies.

Carol Burris, Executive Director of NPE and the report’s author, says: “CREDO is not a neutral academic institution. They are an education research arm of the pro-charter Hoover Institution, and it’s time they are treated as such. We call on policymakers, the general public, and parents to disregard the results of CREDO studies that take tiny results and blow them up using CREDO-invented “Days of Learning.” Their studies are becoming nothing more than propaganda for the charter industry.”

CREDO’s latest report identifies two nonprofits as underwriters of the latest study – The City Fund and The Walton Family – which gave CREDO nearly $3 million during the years of the study. The City Fund is bankrolled by pro-charter billionaires, including John Arnold, Reed Hastings, and Bill Gates. They have a well-established history of supporting the expansion of charter schools and funding agendas to break up school districts and turn them into a patchwork of “portfolio districts.” The goal of the City Fund is to transform 30-50% of city public schools into charter schools.

CREDO also masks its connections to the conservative think tank the Hoover Institution, but the CREDO report authors’ current biographies and resumes link the organizations. CREDO’s Director and the report’s first author is the Education Program Director for Hoover.

NPE says it is time for state agencies to end their research relationship with CREDO and offer detailed student data to credible and independent research organizations instead.

The NPE report takes an honest look at CREDO’s report with the following key sections:

  • A history of CREDO and its connection to the Hoover Institution.
  • Scholarly critiques of CREDO methodology.
  • Trivial differences exaggerated by the CREDO-created construct, ‘Days of Learning’
  • Bias in the “Virtual Twin” methodology.
  • Serious errors in the identification of schools run by Charter Management Organizations.

According to Diane Ravitch, the President of the Network for Public Education, “CREDO and the billionaires who fund them are trying to discredit public schools to persuade the public that public schools are inferior to privately-managed schools. How is this different from the tobacco industry funding research on cigarette safety?”

“It is clear the CREDO reports are now part of a long-game strategy to undermine, weaken, and defund public education. Why does CREDO consider differences that favor public schools in their first report as “meaningless” and “small” but characterize nearly identical differences favoring charters in its third report to be “remarkable”? Same outcomes. Different characterizations,” Ravitch said.

In light of our findings, The Network for Public Education asks CREDO the following question:

Does CREDO represent the interest of its funders and the pro-school choice Hoover Institution or the interests of the public, who deserve an unbiased look at real outcomes for our nation’s charter and public school students?

“Unless CREDO is held accountable, its reports will continue to move from “in fact” to misleading fallacies. And that does a disservice to the charter and public school sectors alike,” concludes the NPE report. 

The Network for Public Education is a national advocacy group whose mission is to preserve, promote, improve, and strengthen public schools for current and future generations of students.
