Sub-Saharan Africa has by far the lowest rates of primary school students who achieve minimum proficiency in math and reading, less than 7% and 14% respectively.
This compares with 30% - 40% achievement rates in the lower middle income countries.
Across Africa, 30 million children of primary school age are not even in school, and many children who are in school suffer from widespread teacher absenteeism.
Overall, the standard of learning outcomes is very poor. This has huge implications for adult skills attainment and contributes to Africa's estimated average 50% youth unemployment, a problem which will worsen as knowledge and skills become ever more important to employability.
Parents are usually willing to pay a significant portion of income towards their children's education, and private schools are growing in popularity.
