People often ask me, “Why don’t the public schools learn from the charter schools?”

Good question.

The top-rated charter school in Minneapolis has lessons to teach the public schools. But I doubt that the public schools should copy those lessons or even if the lessons are legal.

First, the charter school takes half as many students with disabilities. Then, it has double the suspension rate of the public schools. That raises the charter’s test scores. Then the media and legislators say we need more schools like that.

That is the lesson.

Very clever but not very original.
