Johann Neem is the author of an important book about public education titled Democracy’s Schools: The Rise of Public Education in America.

He recently wrote a post for the Brookings Blog in which he warned that anyone who races to embrace school choice should think hard about why public schools were created and what we lose if we abandon them. He reminds us that public schools are about much more than test scores.

He writes:

“Why do we have public schools? For Americans between the Revolution and the Civil War, the reasons were primarily civic. They wanted, first, to ensure that all Americans had the skills, knowledge, and values to be effective citizens. As North Carolina state Senator Archibald Murphey put in an 1816 report, “a republic is bottomed on the virtue of her citizens.”They wanted, second, to foster solidarity during a time of increasing immigration when, like today, Americans’ divisions often led to violence. As the Fond du Lac, Wis., superintendent of schools put it in 1854: In a society divided by religion, race, party, and wealth, public schools would “harmonize the discordant elements” as students “sympathize with and for the other.”

“Earlier Americans also argued that a democracy should develop every child’s potential. This required a rich curriculum in the arts and sciences. As the Rev. William Ellery Channing put it in the 1830s, every person is entitled to liberal education “because he is a man, not because he is to make shoes, nails, or pins.” Indeed, as one Alabama public school advocate argued, schools would not “weaken the self-reliance of the citizen” nor “destroy his individuality,” but “teach him to feel it.”

“Finally, earlier Americans wanted to equalize access. At the time of American independence, education had remained a family responsibility. How did it become a public good? Here, the past speaks directly to the present. Convincing Americans to pay taxes to support other people’s children was not simple. Pennsylvania Superintendent Francis Shunk noted in 1838 that it was no easy task to persuade someone that “in opposition to the custom of the country and his fixed opinions founded on that custom, he has a deep and abiding concern in the education of all the children around him, and should cheerfully submit to taxation for the purpose of accomplishing this great object…

“Historically, the most successful public programs have benefited a broad constituency. When policies are seen as “welfare,” taxpayers resent their money being spent on others. Public education—like Social Security—succeeded because most Americans benefited.

“The principles above guided public education’s advocates. And public schools were—and remain—among America’s most successful institutions. Our public schools struggle largely in places where poverty makes it difficult for students to learn. Our efforts to reform, then, must build on public schools’ immense historical success.”
