I recently posted a letter from a teacher whose message was “this too shall pass.”

Some readers took this as an expression of complacency. Just wait it out, and the billionaires will get so frustrated by their repeated failures that they will move on to disrupt something else or go back to playing polo.

The bottom line is that you never win in a confrontation by digging your head into the sand. Complacency is self-defeating. While you close your eyes to what is happening, the high-stakes testing will get worse, your community public schools will be closed, experienced teachers will be fired, and schooling will become a consumer choice, like buying milk at the grocery store (the analogy that Jeb Bush suggested at the Republican convention in 2012, that picking a school should be as easy as choosing between 1% milk, 2% milk, whole milk, chocolate milk, whatever).

And meanwhile, if we do nothing, we will find that one of the institutions considered essential to our democracy will have been destroyed by free-market ideology and greed. Instead of community public schools, where children learn to work and play together, we will have “choice” schools that increase segregation and that are free to kick out the students they don’t want. Of course, some “public” schools will be retained, as the school of last resort for the children unwanted by the choice schools.

Do any of the billionaires pushing this market-based ideology ever stop to wonder why none of the top-performing school systems in the world have the kind of school choice that they are promoting for the U.S.? Has it occurred to them that the nations they admire–those with the highest test scores–have strong public school systems with well-prepared teachers, but no vouchers and no charters?

The current corporate assault on public education will not pass unless those who oppose it take action. On one level, this means that we must organize for the next elections to support only candidates who support public education. The last election–at the gubernatorial level–was frankly a disaster, with the re-election of Scott Walker in Wisconsin, John Kasich in Ohio, Rick Scott in Florida, Rick Snyder in Michigan, Paul LePage in Michigan, and others who support privatization. The low turnout across the nation showed that not enough people were informed of what was at stake. We must do better next time and elect candidates who will strengthen families, communities, and public schools.

But there is more we can do now. As parents and teachers, we can encourage students not to take the tests. That’s called “opting out.” The tests are created by two or three major corporations that get to decide what our children should know. The results are used to rank and rate children and identify those who are failures and those who are successes. This is ridiculous. Why should the testing corporations be the arbiters of success and failure? Why should they be given the power to label our children? The standardized tests have no diagnostic value; the results come in too late to inform instruction or to provide insight into what children need more or less of in the classroom. In fact, they are utterly worthless. Tests should be written by classroom teachers, who know what they have taught. There is no particular value in knowing how your child compares to children his age in Maine and Arizona. What you really want from a test is an indication, useful to the teacher, of his strengths and weaknesses, a guide to helping him improve where improvement is needed. That is not what you get from standardized testing. What you as a parent or teacher really want is to know that children are engaged in learning, that they learn how to ask good questions and to pursue the answers, that they learn to love the pursuit of knowledge. A standardized test won’t help you reach those goals, indeed it will undermine them by teaching the importance of finding the right answer to someone else’s question.

So here is my advice: Opt out. Stop the machine that produces the data that are used to label your children, to fire his teachers, to close his school. Take away the data and insist that teachers deal with the needs of every child. Do not feed the machine built in D.C. or at Pearson. Be strategic. Do the one thing that only you have the power to do: deny them the data. Use the power you have.

Save the children. Save your schools. Save your community.
