One of the claims of charter advocates is that could supply better education for less money.

These claims have not panned out. When charters enroll the same kids, they usually get the same results. Charters range in quality across a wide span, and some achieve “success” by high rates of attrition or excluding difficult kids.

Now we know that charters don’t save money either. Nor do they direct more resources to the classroom.

The latest report from Innovation Ohio shows that charters in that state have higher administrative costs by far than public schools. The weaker the charter, the more it lends on administration.
