This paper derives efficiency scores for around 8,500 schools in 30 countries, using Programme for International Student Assessment 2012 data and a nonparametric approach called data envelopment analysis as method. On average, achievement scores of schools can be increased by 27%, holding inputs constant. Efficiency scores vary considerably both…

This process is time-consuming, expensive, and prone to error as often (a) humans code inconsistently, and (b) coding reliability in…
