From Elizabeth Green at Gotham Schools (ht to Monty Neill):
New York City’s heralded $75 million experiment in teacher incentive pay — deemed “transcendent” when it was announced in 2007 — did not increase student achievement at all, a new study by the Harvard economist Roland Fryer concludes.
“If anything,” Fryer writes of schools that participated in the program, “student achievement declined.” Fryer and his team used state math and English test scores as the main indicator of academic achievement.
The program, which was first funded by private foundations and then by taxpayer dollars, also had no impact on teacher behaviors that researchers measured. These included whether teachers stayed at their schools or in the city school district and how teachers described their job satisfaction and school quality in a survey.
The program had only a “negligible” effect on a list of other measures that includes student attendance, behavioral problems, Regents exam scores, and high school graduation rates, the study found.
The experiment targeted 200 high-need schools and 20,000 teachers between the 2007-2008 and 2009-2010 school years. The Bloomberg administration quietly discontinued it last year, turning back on the mayor’s early vow to expand the program quickly.
The program handed out bonuses based on the schools’ results on the city’s progress report cards. The report cards grade schools based primarily on how much progress they make in improving students’ state test scores. A so-called “compensation team” at each school decided how to distribute the money — a maximum of $3,000 per teachers union member, if the school completely met its target, and $1,500 per union member if the school improved its report card score by 75%.
The deal was seen as a landmark in 2007 when Mayor Bloomberg announced it with then-United Federation of Teachers President Randi Weingarten by his side. “I am a capitalist, and I am in favor of incentives for individual people,” Bloomberg said then, while Weingarten emphasized that schools could decide to distribute bonuses evenly among educators. She called the program “transcendent.”
In his study, published as a National Bureau of Economic Research working paper, Fryer writes that researchers were surprised to see that schools that won bonuses overwhelmingly decided to distribute the cash fairly evenly among teachers. More than 80 percent of schools that won bonuses gave the same dollar amount to almost all of the eligible educators.
Researchers were also surprised to find that middle school students actually seemed to be worse off. After three years attending schools involved in the project, middle school students’ math and English test scores declined by a statistically significant amount compared to students attending similar schools that were not part of the project. . . .
