Karin Klein wrote education editorials for the Los Angeles Times for years. She now writes freelance, and she wrote this sensible article for the LA Times.

So-called reformers have advocated their view that the way to improve schools is to fire “bad” teachers. The way they would identify “bad” teachers is by whether the test scores of students went up or down or stayed flat. Reformers seldom acknowledged that test scores reflect family income far more than teacher quality.

This hunt for bad teachers has proved fruitless, as scores have misidentified good and bad teachers, good teachers are demoralized by an idiotic way of evaluating their work, and there are teacher shortages now in many districts, as good teachers leave and the pipeline of new teachers has diminishing numbers.

Linda Darling-Hammond once memorably said, “You can’t fire your way to Finland.”

Karin Klein agrees.

One day, when the current era of test-based evaluation is evaluated, reformers will be held accountable for the damage they have done to teachers, students, and public education. That day will come.

Teachers need help and support to become better teachers.

There is no waiting line of great teachers searching for a job.

School districts must work with the teachers they have, making sure they are encouraged and mentored. And paid well.
