Testing is not a substitute for curriculum and instruction. Good education cannot be achieved by a strategy of testing children, shaming educators, and closing schools.

If charter schools are not more successful on average than the public schools they replace, what is accomplished by demolishing public education? What is the rationale for authorizing for-profit charters or charter management organizations with high-paid executives, since their profits and high salaries are paid by taxpayers' dollars?

I support charters, but the right kind of charters. I support charters that support kids who have the highest needs. A charter should be targeting students who are in serious trouble. It should serve students who didn't succeed in public schools when it can help them. Or, at least, charters should agree to accept similar proportions of the kids with the highest needs.

When you succeed at keeping almost everyone in school, you must figure out ways to educate everyone you keep in school.
