At this time of high unemployment, one group of professionals has no shortage of job security: bad teachers. Few public school principals in the country are able to dismiss an incompetent teacher without a protracted, expensive struggle, and therefore firings rarely happen. Yet researchers agree that hiring good teachers, and ditching bad ones, is the best way to improve education.
Nationwide, 2% or fewer teachers are ever fired or fail to have their contracts renewed because of poor performance. Among tenured teachers — those who get job security, typically after two or three years of satisfactory performance — there are often no dismissals at all, according to the U.S. Education Department.
In Arkansas, Delaware, Hawaii, Montana, North Dakota, Pennsylvania, Rhode Island, Utah and Vermont — states in which fewer than half of fourth-graders are proficient at reading or math — the average school district did not remove a single tenured teacher in 2007-08. It's no wonder: Dismissing one teacher can cost upwards of $100,000, and the legal struggle can drag on for years.
A prime example of the irrationality is in New York City, where teachers accused of misconduct or incompetence can spend years in "rubber rooms" — doing nothing, collecting their full salaries and accruing benefits while their cases crawl through the arbitration process.
