Tough questions urgently arise: Is it legal to opt your child out of state tests? Should it be legal? And if it’s not—and ought not be—legal, is it a legitimate act of civil disobedience to refuse to obey such a law?

The recent surge of activity has more than one source. Partly it’s a response to broad concerns about too much testing and disquiet over curricular narrowing and test-prep overkill. Partly it’s a reaction against the Common Core standards, which have lately become controversial. And partly it’s just old-fashioned Rousseauian romanticism about the ends of education and the proper metrics by which to determine whether the right ends are being attained.

Yes, it’s understandable. But is it acceptable?
