In addition to basic infrastructure, what school resources are important to improve learning? This question is hard to answer due to lack of availability of appropriate data. Collaboration between researchers at US universities and a large, well-established educational foundation in India enabled this study to overcome the challenge of data availability. The study used a unique 60-item instrument--with data from 88 government schools--that generated 8 different indices of school resources. The article finds that in schools with more learning-specific facilities and more co-curricular activities children perform well in math, all else being equal. This article discusses the study's limitations and implications for research, policy and practice.
