Study: Teacher bonuses failed to boost test scores

Some states tried to enact merit bonuses for teachers, but most, like Georgia, were unable to get the necessary laws passed. Colorado passed a controversial law that ties teacher pay to student performance and allows the state to strip tenure from low-performing instructors, but the state did not win the Race to the Top grant money it was counting on to help carry out the law.

Only about half of the 300 teachers originally in the Nashville study were left at the end of the three years because some retired, moved to other schools, or stopped teaching math. About 40 teachers got bonuses each year. Overall, the researchers said, test scores rose modestly for both groups of students during the three-year study, suggesting that the financial incentives made no difference.

“It’s not enough to say, ‘I’ll pay you more if you do better.’ You’ve got to help people know how to do better,” said Amy Wilkins, vice president of the Education Trust, a Washington, D.C., think tank. “Absolutely we should reward them once they do better, but to think merit pay alone will get them there is insane.”
