Some costs of teacher tenure
Citing a study by Stanford University researcher Eric Hanushek, Howard notes that bad teachers have a much greater negative effect on student performance than good teachers have a positive effect. Based on student-performance data, Hanushek’s study concluded that dismissing the worst 8 percent of American public school teachers would put American students on par with those of Finland, which has the highest-scoring students in the world. Yet it’s nearly impossible to fire tenured teachers. In Los Angeles, an effort to fire just seven notoriously bad instructors cost the city $3.5 million, and only got rid of four of the teachers.
