Betsy DeVos keeps trying out different metaphors and analogies in her effort to persuade the public that school choice is way better than public schools.

She has referred to cell phones (you choose among many different providers but the government doesn’t underwrite your choice), Uber (you choose but the government doesn’t underwrite your choice), food trucks outside the U.S. Department of Education (because there are no nearby restaurants but the government also doesn’t pay for your lunch).

So she tried again: You choose your college, why not choose your school?

Peter Greene explains here why this analogy fails.

Here a few of his wise observations:

“In the higher education system, it is primarily the interests of students that are at stake. In K-12, all of society has a stake in the system. Public schools do not exist to serve only parents. The interests of the students, their future employers, their future neighbors and co-workers, their future fellow voters, the community as a whole– all of these interests are represented. That’s why all taxpayers chip in (unlike the higher ed system). That means that all stakeholders get a say, and all public schools should be subjected to a considerably higher level of oversight and accountability than a school ike Harvard.

“Why is choice wrong for K-12? Believe it or not, I don’t think it has to be wrong. But as currently proposed and practiced, it’s wrong because

* There must be accountability for where and how public tax dollars are spent (that includes both issues of quality and issues of violating separation of church and state)

* The system must be fully funded. You cannot run three schools for the money previously spent on one. Don’t make it a zero-sum game– fully fund it.

* Do not leave leftover students behind. Do not push students out because they don’t fit your model. If you want choice, make it parents’ choice, not the school’s choice.

* Students before profits. No for-profits choices. And stringent rules on not-for-profits, most of whom are currently just for-profits with good money-laundering systems.

* Total transparency and complete local control.

“None of these are features of the system that brought those students to Harvard. That’s why choice in higher education, while not always very successful, is less objectionable than choice for K-12.”
