Evidence to Policy, a monthly note series on learning what works, highlights studies that evaluate the impact of programs in the critical areas of human development --health, education, social protection, water and sanitation and labor. From how to best supply rural health clinics with drugs to what helps students do better in school, World Bank-supported impact evaluations provide governments and development experts with the information they need to use resources most effectively. As impact evaluations increasingly become more important to policymakers, this series offers a non-technical review of the many innovations the World Bank is supporting, and the growing number of rigorous studies analyzing the impacts of those innovations. The note series is managed by SIEF, which receives generous funding from the British government's Department for International Development and the Children’s Investment Fund Foundation (CIFF).
In Brazil, policymakers from the Ceará state government worked with the World Bank and the Brazilian nongovernmental Lemann Foundation to design a program to improve secondary school teacher effectiveness. The program provided feedback to teachers on their classroom practices and gave them access to expert educational coaching through one-on-one sessions delivered via Skype. With support from the World Bank’s Strategic Impact Evaluation Fund, the World Bank team incorporated an impact evaluation into the program to test the effectiveness of the approach.
The evaluation of an educational pilot program found that giving parents information led to improved test scores, lower fees in the private schools in the village and higher primary school enrollment.
In Tunisia, an evaluation of a program to provide university students with entrepreneurship education and assistance in developing a business plan, found that the program increased self-employment in the short term. However, four years after finishing the program, these same students weren't any more likely than students who didn't take the program to be self- employed. Limited access to capital was a key challenge that many of the program's graduates said they faced.
In India, the Legatum Institute, the World Bank, the British government’s Department for International Development, the educational non-profit Azim Premji Foundation, and the government of the Indian state of Andhra Pradesh worked together to evaluate alternatives for improving education and giving children more choices.
In Indonesia, researchers evaluated a project to expand access to early childhood services in the country’s poorest areas by giving communities grants for preschools and providing teacher training and facilitators to encourage use of services.
In Haiti, World Bank researchers worked with the Ministry of Education to evaluate a pilot program to use digital technology to help keep track of teachers in school and enable more effective monitoring of schools.
Giving parents information led to improved test scores, lower fees in the private schools in the village and higher primary school enrollment. The results indicate that when parents know how well their children are doing in school—and know how well other children are doing in different schools—it can spur better learning.
In Indonesia, the World Bank worked with the government to set up and evaluate alternative ways to improve parents' knowledge of and involvement in the management of money that the government gives to schools for operational costs.
A study found that when primary school children get deworming treatment, their younger siblings showed cognitive gains, perhaps because of fewer worms in the community.

In Haiti, most primary schools aren’t government run and they charge fees. A program that gives schools vouchers to cover fees allows children to go to school for free, relieving the financial burden on families, and reduces grade repetition, an impact evaluation found.

The Philippines is successfully using conditional cash transfers to improve health and education for the poorest families, but the program hasn't been effective at raising school enrollment for older children. Based on the evaluation, the government has increased the transfer amount for older children.
In Tanzania, an innovative conditional cash transfer program that relies on local communities to administer the payments has succeeded in helping the country’s poorest citizens. As the results of a recent impact evaluation indicate, cash transfer systems can be adapted to work well in low-income countries that don’t have a strong central government to administer them.
Power Point Summary
In Cambodia, a scale-up of early childhood development programs ran into problems, which affected the evaluation and raised important lessons for policymakers and groups working on bringing such programs to scale.

In Colombia, researchers used administrative data to analyze the long-term impact of conditional cash transfers on schooling.
This bulletin showcases a World Bank supported study in Cambodia, where researchers set out to study the effects of scholarships on encouraging primary school students to continue their studies in lower secondary school – and whether bigger grants worked better than smaller ones. The results of the study underscore the importance impact evaluation can have for policymakers, even as researchers plan a second round of data collection to answer some important questions raised by the results.

In Indonesia, the World Bank worked with the Government of Indonesia on a community grant program to boost the use of health and education services. The impact evaluation built into the program found that cash transfers to rural communities led to positive impacts on average across health and education indicators, with a strong decline in malnutrition.
To understand whether low-cost private schools can improve access to education and promote student learning, the World Bank evaluated a new public-private education partnership in Pakistan at the request of the government. Private schools receive a per-student monthly subsidy in exchange for waiving tuition and meeting testing standards. By linking the subsidy to student learning, the program aims to push schools to perform better. The evaluation found that the threat of losing the subsidy worked.
Researchers measured the relative effectiveness of a pilot program implemented by the Indonesian government to test measures to strengthen school committees and improve accountability, thereby leading to better student learning. The pilot found that the most effective way to improve student test scores was to support democratic elections for committee members and strengthen ties between the committees and local groups.

A World Bank-supported study reviewed the impact of a public-private partnership in Colombia that places computers in public schools. The study found that students in participating schools did not show improved test scores, raising questions about the effectiveness of the program, which included teacher training in how to use the computers as teaching aids. Bad news is sometimes good news, blogged HDN Chief Economist Ariel Fiszbein, because it reminds us that “achieving results is not as simple as we sometimes seem to believe.”
This bulletin takes a look at a World Bank supported study in Andhra Pradesh, India, where our team and their counterparts set out to explore whether paying teachers bonuses based on student test scores is more effective at boosting scores than giving schools extra money for supplies or teachers. The results of the project will not end the debate over how to encourage more effective teaching. But it does offer some powerful ideas that can help inform policy in this critical area across the developing world.
