The problem with teacher tenure in the US

Fran Bruni writes in the NY Times:

Mike Johnston’s mother was a public-school teacher. So were her mother and father. And his godfather taught in both public and private schools.

So when he expresses the concern that we’re not getting the best teachers into classrooms or weeding out the worst performers, it’s not as someone who sees the profession from a cold, cynical distance.

What I hear in his voice when he talks about teaching is reverence, along with something else that public education could use more of: optimism.

He rightly calls teachers “the single most transformative force in education.”

But the current system doesn’t enable as many of them as possible to rise to that role, he says. And a prime culprit is tenure, at least as it still exists in most states.

“It provides no incentive for someone to improve their practice,” he told me last week. “It provides no accountability to actual student outcomes. It’s the classic driver of, ‘I taught it, they didn’t learn it, not my problem.’ It has a decimating impact on morale among staff, because some people can work hard, some can do nothing, and it doesn’t matter.”

I sat down with Johnston, a Democrat who represents a racially diverse chunk of this city in the State Senate, because he was the leading proponent of a 2010 law that essentially abolished tenure in Colorado. To earn what is now called “non-probationary status,” a new teacher must demonstrate student progress three years in a row, and any teacher whose students show no progress for two consecutive years loses his or her job protection.

Sounds wonderful. What will be interesting to assess over the years is how states that passed laws like this compare to states that do not, in terms of student achievement?
