Biography
Jishnu Das is a Lead Economist in the Development Research Group (Human Development Team) at the World Bank and a Visiting Fellow at the Center for Policy Research, New Delhi. Jishnu’s work focuses on the delivery of basic services, particularly health and education. He has worked on the quality of health care, mental health, information in health and education markets, child learning and test-scores and the determinants of trust. His work has been published in leading economics, health and education journals and widely covered in the media and policy forums. In 2011 he was part of the core team on the World Development Report on Gender and Development. He received the George Bereday Award from the Comparative and International Education Society and the Stockholm Challenge Award for the best ICT project in the public administration category in 2006, and the Research Academy award from the World Bank in 2013. He is currently working on long-term projects on health and education markets in India and Pakistan.

India Shining and Bharat Drowning : Comparing Two Indian States to the Worldwide Distribution in Mathematics Achievement
(World Bank, Washington, DC, 2008-06)This paper uses student answers to publicly released questions from an international testing agency together with statistical methods from Item Response Theory to place secondary students from two Indian states -Orissa and Rajasthan -on a worldwide distribution of mathematics achievement. These two states fall below 43 of the 51 countries for which data exist. The bottom 5 percent of children rank higher than the bottom 5 percent in only three countries-South Africa, Ghana and Saudi Arabia. But not all students test poorly. Inequality in the test-score distribution for both states is next only to South Africa in the worldwide ranking exercise. Consequently, and to the extent that these two states can represent India, the two statements "for every ten top performers in the United States there are four in India" and "for every ten low performers in the United States there are two hundred in India" are both consistent with the data. The combination of India's size and large variance in achievement give both the perceptions that India is shining even as Bharat, the vernacular for India, is drowning. Comparable estimates of inequalities in learning are the building blocks for substantive research on the correlates of earnings inequality in India and other low-income countries; the methods proposed here allow for independent testing exercises to build up such data by linking scores to internationally comparable tests. -

Learning Levels and Gaps in Pakistan
(World Bank, Washington, DC, 2006-11)The authors report on a survey of primary public and private schools in rural Pakistan with a focus on student achievement as measured through test scores. Absolute learning is low compared with curricular standards and international norms. Tested at the end of the third grade, a bare majority had mastered the K-I mathematics curriculum and 31 percent could correctly form a sentence with the word "school" in the vernacular (Urdu). As in high-income countries, bivariate comparisons show that higher learning is associated with household wealth and parental literacy. In sharp contrast to high-income countries, these gaps decrease dramatically in a multivariate regression once differences between children in the same school are looked at. Consequently, the largest gaps are between schools. The gap in English test scores between government and private schools, for instance, is 12 times the gap between children from rich and poor families. To contextualize these results within a broader South Asian context, the authors use data from public schools in the state of Uttar Pradesh in India. Levels of learning and the structure of the educational gaps are similar in the two samples. As in Pakistan, absolute learning is low and the largest gaps are between schools: the gap between good and bad government schools, for instance, is 5 times the gap between children with literate and illiterate mothers. -

Religious School Enrollment in Pakistan : A Look at the Data
(World Bank, Washington, DC, 2005-02)Bold assertions have been made in policy reports and popular articles on the high and increasing enrollment in Pakistani religious schools, commonly known as madrassas. Given the importance placed on the subject by policymakers in Pakistan and those internationally, it is troubling that none of the reports and articles reviewed based their analysis on publicly available data or established statistical methodologies. The authors of this paper use published data sources and a census of schooling choice to show that existing estimates are inflated by an order of magnitude. Madrassas account for less than 1 percent of all enrollment in the country and there is no evidence of a dramatic increase in recent years. The educational landscape in Pakistan has changed substantially in the past decade, but this is due to an explosion of private schools, an important fact that has been left out of the debate on Pakistani education. Moreover, when the authors look at school choice, they find that no one explanation fits the data. While most existing theories of madrassa enrollment are based on household attributes (for instance, a preference for religious schooling or the household s access to other schooling options), the data show that among households with at least one child enrolled in a madrassa, 75 percent send their second (and/or third) child to a public or private school or both. Widely promoted theories simply do not explain this substantial variation within households. -

India Shining and Bharat Drowning : Comparing Two Indian States to the Worldwide Distribution in Mathematics Achievement
( 2010)Increasing evidence suggests that the level and distribution of cognitive skills is more important to economic development than absolute measures of schooling attainment, and that income and skill inequality are inextricably linked. Yet for most of the developing world no internationally comparable estimates of cognitive skills exist. This paper uses student answers to publicly released questions from an international testing agency together with statistical methods from Item Response Theory to place secondary students from two Indian states--Orissa and Rajasthan--on a worldwide distribution of mathematics achievement. These two states fall below 43 of the 51 countries for which data exist. The bottom 5% of children rank higher than the bottom 5% in only three countries--South Africa, Ghana, and Saudi Arabia. But not all students test poorly. Inequality in the test-score distribution for both states is next only to South Africa. The combination of India's size and large variance in achievement give both the perceptions that India is shining even as Bharat, the vernacular for India, is drowning. How India's development unfolds will depend critically on how the skill distribution evolves and how low- and high-skilled workers interact in the labor market. -

Do Value-Added Estimates Add Value? Accounting for Learning Dynamics
( 2009-09-01)Evaluations of educational programs commonly assume that what children learn persists over time. The authors compare learning in Pakistani public and private schools using dynamic panel methods that account for three key empirical challenges to widely used value-added models: imperfect persistence, unobserved student heterogeneity, and measurement error. Their estimates suggest that only a fifth to a half of learning persists between grades and that private schools increase average achievement by 0.25 standard deviations each year. In contrast, estimates from commonly used value-added models significantly understate the impact of private schools on student achievement and/or overstate persistence. These results have implications for program evaluation and value-added accountability system design. -

Do Value-Added Estimates Add Value? Accounting for Learning Dynamics
( 2011)This paper illustrates the central role of persistence in estimating and interpreting value-added models of learning. Using data from Pakistani public and private schools, we apply dynamic panel methods that address three key empirical challenges: imperfect persistence, unobserved heterogeneity, and measurement error. Our estimates suggest that only one-fifth to one-half of learning persists between grades and that private schools increase average achievement by 0.25 standard deviations each year. In contrast, value-added models that assume perfect persistence yield severely downward estimates of the private school effect. Models that ignore unobserved heterogeneity or measurement error produce biased estimates of persistence.
