Class-Size Effects in School Systems around the World: Evidence from Between-Grade Variation in TIMSS.
Woessmann, Ludger; West, Martin R.
Using the international database of the Third International Mathematics and Science Study (TIMSS), this study estimated the effect of class size on student performance in 18 countries, combining school fixed effects and instrumental variables to identify random class-size variation between 2 adjacent grades within individual schools. Conventional estimates of class-size effects are shown to be severely biased by the nonrandom placement of students between and within schools. Smaller classes exhibit beneficial effects only in countries with relatively low teacher salaries. While sizeable beneficial effects of smaller classes were found in Greece and Iceland, the possibility of even small effects is rejected for Japan and Singapore. In 121 countries, the findings rule out large class-size effects. An appendix discusses the sample of countries. (Contains 4 figures, 19 tables, and 23 references.) (SLD)
