Eric.ed.gov – The Impact of Incentives on Effort: Teacher Bonuses in North Carolina. Program on Education Policy and Governance Working Papers Series. PEPG 10-06

Teacher effort, a critical component of education production, has been largely ignored in the literature due to measurement difficulties. Using a principal-agent model, North Carolina public school data, and the state’s unique accountability system that rewards teachers for school-level academic growth, we show that we can distill effort from teacher absence data and capture its effect on student achievement in a structural framework. We find that: (1) Incentives lead teachers to try harder. The bonus program reduced the number of sick days taken by about 0.6 days for an average teacher; (2) When teachers try harder, students do better. Increased effort of teachers translates into improved student performance. Estimates show that standardized reading scores increased by about 1.3% of a standard deviation and standardized math scores by about 0.9% of a standard deviation; and (3) Group-level incentives can actually be more powerful than individual-level incentives. Policy simulations from the model estimates show that an individual bonus program would actually produce weaker incentive effects. While free-rider effects are eliminated, individual incentives push a majority of teachers into one of two categories: those who would qualify for the bonus even without trying and others would not qualify no matter how hard they worked. A bibliography is included. (Contains 3 figures and 10 footnotes.)

Jeg er ejer af og driver bl.a. hjemmesiderne www.lærklokken.dk og www.iundervisning.dk, ggbkursus.dk og er tidligere fagredaktør på matematik på emu.dk. Jeg går ind for, at læring skal være let tilgængelig og i størst mulig omfang gratis at benytte.
