This article discusses merit pay for teachers and its impact on teacher motivation and student achievement. It provides an overview of the purpose of merit pay systems and definitions of key terms. It then discusses the Houston Independent School District's implementation of a merit pay system in 2005 and the positive results it produced, including improved student test scores, narrowed achievement gaps, fewer teacher absences, and a 19% drop in teacher turnover. The concluding remarks recommend further study of whether these outcomes could be achieved in other school districts with merit pay systems.
