For most children, turning 10 is an exciting moment. They're learning more about the world and expanding their horizons. But too many children－more than half of all 10-year-olds in low-and middle-income countries－cannot read and understand a simple story. We are in the middle of a global learning crisis that stifles opportunities and aspirations of hundreds of millions of children. That is unacceptable.

In October, we released data to support a new learning target: by 2030, we want to cut, by at least half, the global level of learning poverty.

Learning to read is an especially critical skill: it opens a world of possibilities, and it's the foundation on which other essential learning is built－including numeracy and science. Wiping out learning poverty－defined as the percentage of children who can't read and understand a simple story by age 10－is an urgent matter. It's key to eliminating poverty in general and boosting shared prosperity. It's key to helping children achieve their potential.

Little progress made in past several years

But over the last several years, progress in reducing learning poverty has been stagnant. Globally, between 2000 and 2017, there has only been a 10 percent improvement in learning outcomes for primary school-aged children. If this pace continues, 43 percent of 10-year-olds won't be able to read in 2030.

While some countries have made improvements over the years, there are significant discrepancies between low-income and high-income countries, and regions within countries. Learning poverty is a global crisis, but it is particularly stark in Africa where close to 86 percent of children cannot read or understand a simple story at age 10.

The good news is, the children who will turn 10 in 2030 will be born only next year. So, if we work urgently, there is an opportunity to reverse this trend. The target we've set is ambitious but achievable－and should galvanize action toward achieving the fourth of the 17 Sustainable Development Goals－ensuring quality education for all. It will require nearly tripling the rate of progress worldwide, which can be done if every country can match the performance of the countries that made the most progress between 2000 and 2015.

Several countries are showing that it's possible. In Kenya, the government's national reading program has more than tripled the percentage of grade two students reading at an appropriate level. This was accomplished through technology-enabled teacher coaching, teacher guides, and delivering one book per child.

Effective curriculum produces better results

In Vietnam, a lean, effective curriculum ensures that the basics are covered, there is deep learning of fundamental skills, and all children have reading materials. Learning outcomes of Vietnamese students in the bottom 40 percent of the income ladder are as high, or higher, than the average student in high-income countries.

The challenges of reducing learning poverty will differ between countries and regions. In some countries, access to school remains an enormous problem-258 million young people were out of school globally in 2018. In other countries, children are in classrooms but not learning. By setting a global target, the World Bank can work with countries to define their own national learning targets. Cutting learning poverty in half by 2030 is only an intermediate goal. Our ambition is to work with governments and development partners to bring that number to zero.

As the largest financier of education in low-and middle-income countries, the World Bank will work with countries to promote reading proficiency in primary schools. Policies include providing detailed guidance and practical training for teachers, ensuring access to more and better age-appropriate texts, and teaching children in the language they use at home.

The World Bank is also working with governments and development partners to improve entire education systems, so advancements in literacy can be sustained and scaled up. That means making sure children come to school prepared and motivated to learn; teachers are effective and valued and have access to technology; classrooms provide a well-equipped space for learning; schools are safe and inclusive; and education systems are well-managed.

Agenda support for learning

An ambitious measurement and research agenda supports these efforts and includes measurement of both learning outcomes and their drivers, continued research and innovation, and the smart use of new technologies on how to build foundation skills.

The learning crisis not only wastes the children's potential, it hurts entire economies. It will have a negative impact on future workforces and economic competitiveness－as the World Bank's Human Capital Index shows that, globally, the productivity of the average child born today is expected to be only 56 percent of what it would be if countries invested enough in health and education.

Eliminating learning poverty must be a priority, just like ending hunger and extreme poverty. It won't be easy, but we can't back down from the challenge. We owe it to the children all over the world to set our sights high, so they can too.
