Toward Successful Development Policies: Insights from Research in Development Economics
(World Bank, Washington, DC, 2020-01)What major insights have emerged from development economics in the past decade, and how do they matter for the World Bank? This challenging question was recently posed by World Bank Group President David Malpass to the staff of the Development Research Group. This paper assembles a set of 13 short, nontechnical briefing notes prepared in response to this request, summarizing a selection of major insights in development economics in the past decade. The notes synthesize evidence from recent research on how policies should be designed, implemented, and evaluated, and provide illustrations of what works and what does not in selected policy areas. -

Teacher Performance-Based Incentives and Learning Inequality
(World Bank, Washington, DC, 2020-09)This study evaluates the impacts of low-cost, performance-based incentives in Tanzanian secondary schools. Results from a two-phase randomized trial show that incentives for teachers led to modest average improvements in student achievement across different subjects. Further, withdrawing incentives did not lead to a "discouragement effect" (once incentives were withdrawn, student performance did not fall below pre-baseline levels). Rather, impacts on learning were sustained beyond the intervention period. However, these incentives may have exacerbated learning inequality within and across schools. Increases in learning were concentrated among initially better-performing schools and students. At the same time, learning outcomes may have decreased for schools and students that were lower performing at baseline. Finally, the study finds that incentivizing students without simultaneously incentivizing teachers did not produce observable learning gains. -

Heterogenous Teacher Effects of Two Incentive Schemes: Evidence from a Low-Income Country
(World Bank, Washington, DC, 2021-05)This paper reports on a randomized evaluation of two teacher incentive programs, which were conducted in a nationally representative sample of 420 public primary schools in Guinea. In 140 schools, high-performing teachers were rewarded in-kind, with the value of goods increasing with level of performance. In another 140 schools, high-performing teachers received a certificate and public recognition from the government. After one year, the in-kind program improved learning by 0.24 standard deviations, while the recognition treatment had a smaller and statistically insignificant impact. After two years, the effect from the in-kind program was smaller (0.16 standard deviations) and not significant; the paper provides suggestive evidence that the reduction may be due to the onset of an Ebola outbreak. The effects of the recognition program remained small and insignificant. The effects differed by teacher gender: for female teachers, both programs were equally effective, while for male teachers, only the in-kind program led to statistically significant effects. -

Learning-adjusted years of schooling: Defining a new macro measure of education
(Elsevier, 2020-08-01)The standard summary metric of education-based human capital used in macro analyses is a quantity-based one: The average number of years of schooling in a population. But as recent research shows, students in different countries who have completed the same number of years of school often have vastly different learning outcomes. We therefore propose a new summary measure, the Learning-Adjusted Years of Schooling (LAYS). This measure combines quantity and quality of schooling into a single easy-to-understand metric of progress, revealing considerably larger cross-country education gaps than the standard metric. We show that the comparisons produced by this measure are robust to different ways of adjusting for learning and that LAYS is consistent with other evidence, including other approaches to quality adjustment. Like other learning measures, LAYS reflects learning, and barriers to learning, both inside and outside of school; also, cross-country comparability of LAYS rests on assumptions related to learning trajectories and the validity, reliability, and comparability of test data. Acknowledging these limitations, we argue that LAYS nonetheless improves on the standard metric in key ways. -

Information, Knowledge, and Behavior: Evaluating Alternative Methods of Delivering School Information to Parents
(University of Chicago Press, 2022-01-01)This paper evaluates alternative approaches to disseminating information about a school-based management program in Indonesia. Low-intensity approaches, sending a letter from the principal or a colorful pamphlet home with the child, had no impact. Holding a facilitated meeting with school stakeholders or sending targeted text messages (SMSs) to parents increased knowledge and participation. Facilitated meetings increased overall knowledge, fostered a feeling of transparency, and increased participation in formal channels for providing feedback to the school. SMSs increased knowledge about specific aspects of the program, such as the grant amount, and increased participation through informal channels. -

How to Improve Education Outcomes Most Efficiently? A Comparison of 150 Interventions Using the New Learning-Adjusted Years of Schooling Metric
(World Bank, Washington, DC, 2020-10)Many low- and middle-income countries lag far behind high-income countries in educational access and student learning. Limited resources mean that policymakers must make tough choices about which investments to make to improve education. Although hundreds of education interventions have been rigorously evaluated, making comparisons between the results is challenging. Some studies report changes in years of schooling; others report changes in learning. Standard deviations, the metric typically used to report learning gains, measure gains relative to a local distribution of test scores. This metric makes it hard to judge if the gain is worth the cost in absolute terms. This paper proposes using learning-adjusted years of schooling (LAYS) -- which combines access and quality and compares gains to an absolute, cross-country standard -- as a new metric for reporting gains from education interventions. The paper applies LAYS to compare the effectiveness (and cost-effectiveness, where cost is available) of interventions from 150 impact evaluations across 46 countries. The results show that some of the most cost-effective programs deliver the equivalent of three additional years of high-quality schooling (that is, schooling at quality comparable to the highest-performing education systems) for just $100 per child -- compared with zero years for other classes of interventions. -

Cambodia: Can New and Improved Preschools Improve Child Development in Rural Communities?
(World Bank, Washington, DC, 2020-05)Early childhood is a critical period for growth and development. Research shows that giving young children enough nurturing and stimulating experiences during these early years not only improves their chances of success in school but can also help them succeed and be more productive later in life. Although access to preschool has increased substantially in recent years, in many low-income communities’ children don’t receive any educational services before they start primary school. In some cases, parents aren’t aware of the value of early education and might not take advantage of opportunities to enroll their children in preschool, even when services are available. -

Identifying Effective Teachers: Lessons from Four Classroom Observation Tools
(World Bank, Washington, DC, 2020-08)Four different classroom observation instruments -- from the Service Delivery Indicators, the Stallings Observation System, the Classroom Assessment Scoring System, and the Teach classroom observation instrument -- were implemented in about 100 schools across four regions of Tanzania. The research design is such that various combinations of tools were administered to various combinations of teachers, so these data can be used to explore the commonalities and differences in the behaviors and practices captured by each tool, the internal properties of the tools (for example, how stable they are across enumerators, or how various indicators relate to one another), and how variables collected by the various tools compare to each other. Analysis shows that inter-rater reliability can be low, especially for some of the subjective ratings; principal components analysis suggests that lower-level constructs do not map neatly to predetermined higher-level ones and suggest that the data have only few dimensions. Measures collected during teacher observations are associated with student test scores, but patterns differ for teachers with lower versus higher subject content knowledge. -

Are Teachers in Africa Poorly Paid? Evidence from 15 Countries
(World Bank, Washington, DC, 2020-08)Pay levels for public sector workers—and especially teachers—are a constant source of controversy. In many countries in Sub-Saharan Africa, protests and strikes suggest that pay is low, while simple comparisons to average national income per capita suggest that it is high. This study presents data on teacher pay from 15 African countries, along with five comparator countries from other regions. The results suggest that in several (seven) countries, teachers' monthly salaries are lower than other formal sector workers with comparable levels of education and experience. However, in all of those countries, teachers report working significantly fewer hours than other workers, so that their hourly wage is higher. Teachers who report fewer hours are no more likely to report holding a second job, although teachers overall are nearly two times more likely to hold a second job than other workers. With higher national incomes, the absolute value of teacher salaries rises, but they fall as a percentage of income per capita. The study explores variation across types of teacher contracts, the association between teacher pay and student performance, and the association between teacher pay premia and other aspects of economies. -

Preparation, Practice, and Beliefs: A Machine Learning Approach to Understanding Teacher Effectiveness
(World Bank, Washington, DC, 2021-11)This paper uses machine learning methods to identify key predictors of teacher effectiveness, proxied by student learning gains linked to a teacher over an academic year. Conditional inference forests and the least absolute shrinkage and selection operator are applied to matched student-teacher data for math and Kiswahili from grades 2 and 3 in 392 schools across Tanzania. These two machine learning methods produce consistent results and outperform standard ordinary least squares in out-of-sample prediction by 14–24 percent. As in previous research, commonly used teacher covariates like teacher gender, education, experience, and so forth are not good predictors of teacher effectiveness. Instead, teacher practice (what teachers do, measured through classroom observations and student surveys) and teacher beliefs (measured through teacher surveys) emerge as much more important. Overall, teacher covariates are stronger predictors of teacher effectiveness in math than in Kiswahili. Teacher beliefs that they can help disadvantaged and struggling students learn (for math) and they have good relationships within schools (for Kiswahili), teacher practice of providing written feedback and reviewing key concepts at the end of class (for math), and spending extra time with struggling students (for Kiswahili) are highly predictive of teacher effectiveness. As is teacher preparation on how to teach foundational topics (for both Math and Kiswahili). These results demonstrate the need to pay more systematic attention to teacher preparation, practice, and beliefs in teacher research and policy.
