Study shows reducing class size may be more cost-effective than most medical interventions

October 16, 2007 -- Reducing the number of students per classroom in U.S. primary schools may be more cost-effective than most public health and medical interventions, according to a study by researchers at Columbia University Mailman School of Public Health and the Virginia Commonwealth University. The study indicates that class-size reductions would generate more quality-adjusted life-year gains per dollar invested than the majority of medical interventions. The findings will be published in the November issue of the American Journal of Public Health.

The researchers estimated the health and economic effects of reducing class sizes from 22–25 students to 13–17 students in kindergarten through grade 3 nationwide, based on an intervention tested in Project STAR (Student Teacher Achievement Ratio), a large multi-school randomized trial that began in 1985. Project STAR is considered the highest quality long-term experiment to date in the field of education.
