As we have seen again and again, the corporate education industry is eager to break into U.S. public education and turn it into a free marketplace, where they can monetize the schools and be assured of government subsidization. On the whole, these privatized institutions do not produce higher test scores than regular public schools, except for those that cherry-pick their students and exclude the neediest and lowest performing students. The promotion of privatization by philanthropies, by the U.S. Department of Education, by right-wing governors (and a few Democratic governors like Cuomo of New York and Malloy of Connecticut), by the hedge fund industry, and by a burgeoning education equities industry poses a danger to our democracy. In some communities, public schools verge on bankruptcy as charters drain their resources and their best students. Nationwide, charter schools have paved the way for vouchers by making “school choice” non-controversial.

Yes, education is in crisis. The profession of teaching is threatened by the financial powerhouse Teach for America, which sells the bizarre idea that amateurs are more successful than experienced teachers. TFA — and the belief in amateurism — has also facilitated the passage of legislation to strip teachers of basic rights to due process and of salaries tied to experience and credentials.

Education is in crisis because of the explosion of testing and the embrace by government of test scores as both the means and the end of education. The scores are treated as a measure of teacher effectiveness and school effectiveness, when they are in fact a measure of the family income of the students enrolled in the school. The worst consequence of the romance with standardized testing is that children are ranked, sorted, and assigned a value based on scores that are not necessarily scientific or objective. Children thus become instruments, tools, objects, rather than unique human beings, each with his or her own potential.

Education is in crisis because of the calculated effort to turn it into a business with a bottom line. Schools are closed and opened as though they were chain stores, not community institutions. Teachers are fired based on flawed measures. Disruption is considered a strategy rather than misguided and inhumane policy. Children and educators alike are simply data points, to be manipulated by economists, statisticians, entrepreneurs, and dabblers in policy.

Education has lost its way, lost its purpose, lost its definition. Where once it was about enlightening and empowering young minds with knowledge, exploring new worlds, learning about science and history, and unleashing the imagination of each child, it has become a scripted process of producing test scores that can supply data.

Education is in crisis. And we must organize to resist, to push back, to fight the mechanization of learning, and the standardization of children.
