This article in the NY Times describes a study of reactions (or lack thereof) to high-quality teachers.

Excerpt:

As things stand now, according to a study by the New Teacher Project, a Brooklyn-based policy group, many school managers make no distinction between high-performing and low-performing teachers. The result is that poor teachers stick around while good teachers go elsewhere or leave the profession, frustrated because they are not promoted, rewarded with better pay, or even simply acknowledged.

The study covered four large urban school districts consisting of more than 2,100 schools and nearly a million and half students. It measured about 20,000 teachers by how much academic growth students showed in a given year. On average, the highest-performing teachers — about one-fifth of those studied — helped students learn two to three additional months’ worth of math and reading, compared with the average teacher, and five to six months more compared with low-performing teachers.

The students clearly noticed the difference. In surveys, they were more likely to report that the better teachers cared about them, made learning enjoyable, and did not let them give up on difficult problems. Even so, high-performing teachers said that administrators were often indifferent to their performance, neither rewarding nor praising them. Only about a quarter of the high performers were offered leadership roles in the schools. Many said they were not even encouraged to stay another year. And schools were nearly as likely to offer leadership opportunities to low performers.

In short, most school cultures do not seem to value excellence in teaching or appreciate how difficult it is to achieve. The costs are great: an estimated 10,000 high-performing teachers leave the nation’s 50 largest districts in a year, either for other districts or to exit the profession. That is a heavy loss, but it is especially costly to low-performing school systems that should be strengthening the teacher corps year upon year.
