A meta-analysis published in the American Educational Research Journal looks at the association between teacher pay incentives and pupils’ test scores, and suggests that teacher pay incentives have the potential to improve pupil test scores in some contexts.
Lam D Pham and colleagues analysed effect sizes across 37 studies, 26 of which were conducted in the US. To be included in the meta-analysis, studies had to include a sample comprising teachers and pupils in K-12 education (Year 1 to Year 13) located in a school district or area that had a teacher pay incentive programme. Studies also had to use a randomised controlled trial with a business-as-usual comparison group, and report on pupil outcomes on standardised tests.
Overall, among the US-based studies, the effect of teacher pay incentives on pupil test scores was positive (effect size +0.04), however, this varied across subjects and settings. The average effect size of pay incentives on pupils’ maths test scores (+0.05) was larger than the effect on English test scores (+0.03). Pay incentives for elementary (primary) school teachers were associated with larger effects (+0.10) than middle school teachers (+0.01). In addition, larger pay incentives, and pay incentives that are based on multiple measures of teacher effectiveness, were associated with larger effect sizes.
