What Do Standardized Test Scores Really Measure? David Berliner Explains


David Berliner has been teaching about education policy and writing books on education and school psychology for decades. The best known for readers outside colleges of education are The Manufactured Crisis and 50 Myths and Lies that Threaten America’s Public Schools. Yesterday in a pithy column published by Valerie Strauss in the Washington Post, Berliner explains why none of our current strategies for school reform will work. Not corporate school reform. Not test and punish accountability. Not blaming school teachers. Not charter school and voucher strategies that allow some promising students to escape public schools—the plans favored by Donald Trump and Betsy DeVos. Berliner’s analysis is definitive. He demonstrates that our society has been on the wrong path for decades.
The test scores by which our society now judges schools don’t really measure the quality of schools: “As income increases per family from our poorest families (under the 25th percentile in wealth), to working class (26th-50th percentile in family wealth), to middle class (51st to 75th percentile in family wealth), to wealthy (the highest quartile in family wealth), mean scores go up quite substantially. In every standardized achievement test whose scores we use to judge the quality of the education received by our children, family income strongly and significantly influences the mean scores obtained.”  Berliner continues: “Similarly, as the families served by a school increase in wealth from the lowest quartile in family wealth to the highest quartile in family wealth, the mean score of all the students at those schools goes up quite substantially. Thus, characteristics of the cohort attending a school strongly influence the scores obtained by the students at that school.”
Berliner adds that, while critics of public education complain about overall U.S. scores on international tests, our wealthiest students do as well as the highest scoring students in the world: “We learn that in the United States, wealthy children attending public schools that serve the wealthy are competitive with any nation in the world. Since that is the case, why would anyone think our public schools are failing? When compared with other nations, someWhat Do Standardized Test Scores Really Measure?
